For over 500 days, the Hyper-Angular Rainbow Polarimeter 2 (HARP2), a high-tech instrument built by UMBC researchers and students, has been orbiting Earth on NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite, capturing stunning data about our planet’s atmosphere, surface, and oceans. UMBC celebrated this milestone with lab tours, a poster session showcasing student research, and talks from the PACE instrument and science teams and university leadership, highlighting the instrument’s success and the hands-on role students play in this NASA mission.

“There is palpable pride on our campus in UMBC’s contributions to the PACE mission,” shares Karl V. Steiner, vice president for research and creative achievement. “Because much of the HARP2 instrument was created with strong involvement from both undergraduate and graduate students, this mission truly combines the best of our research and education missions. HARP2 is clearly a milestone in our 30-plus year partnership with NASA Goddard.’’   

HARP2’s story builds on UMBC’s earlier work with the original HARP, a pint-sized CubeSat launched in 2019 that earned the American Institute of Aeronautics and Astronautics’ SmallSat Mission of the Year award in 2021. That tiny satellite showed the world how capturing data from many angles could reveal a more complete picture of the atmospheric composition, including the roles of clouds, dust, and smoke. 

HARP2, launched in February 2024, takes HARP’s work further, collecting detailed data from a survey of the entire globe every two days. HARP2 collects in half a day the same amount of data collected by HARP in its entire two-year flight. Researchers have also enhanced data analysis methods, allowing scientists to glean even more accurate and detailed information from the raw data transmitted from space. Alongside PACE’s Ocean Color Instrument (OCI), HARP2 is helping scientists study everything from air quality to climate patterns, and painting a fuller picture of Earth’s systems.

What sets HARP2 apart is its ability to see the atmosphere in 3D-like detail, thanks to its unique “hyper-angular” views. “The instrument is working, it’s producing great data, and the community is starting to use it,” shares Vanderlei Martins, director of the Earth and Space Institute (ESI) at UMBC and the HARP team lead. Scientists across the U.S. and beyond are tapping into HARP2’s data to track pollution, measure cloud droplet properties, and more. Unlike other satellites, HARP2 can distinguish whether particles in the air are smoke, dust, or pollution, offering clues that help us understand air quality and climate impacts.

To ground-truth the data coming from HARP2, some members of the team traveled to Bolivia. They flew drones over high-altitude Lake Titicaca and the Salar de Uyuni salt flat to collect data that complements HARP2’s space-based views. With less atmosphere above them, these sites offer a clearer match to satellite observations, helping refine the science.

An “explosion” of science

Students at UMBC are deeply involved, from building and calibrating HARP2 to digging into its data. Graduate students in the atmospheric physics program work closely with faculty and NASA engineers, even on the most sensitive elements of the project. 

During testing for HARP2, “I was given the opportunity not only to see the initial calibration process, but then to see the team respond to a catastrophic failure, and then come back from it,” recalls Rachel Smith, an atmospheric physics Ph.D. student. “To watch them come together in support of the project and not miss a beat putting it back together was really incredible to see.” Early in her time with the group, Smith got to hold the instrument. “It’s a cool feeling, that I picked up and worked on this thing that’s now in space,” she says.  

Nirandi Jayasinghe, another atmospheric physics Ph.D. student, recalls the earliest data coming in. “We were all here—graduate students, scientists, and engineers—in this very room, doing stuff piece by piece to visualize ‘first light’ from HARP2,” she says. “I don’t think I’ve seen this much synergy between people anywhere else.”

Over time, the team has grown to meet the rising demands of the project. “I’ve seen how the group has gone from just me, Dominik [Cieslak], Roberto [Borda], and a couple of other engineers to now three, four, five grad students at once tackling different and interesting science questions,” shares Brent McBride ’14, physics, Ph.D. ’22, atmospheric physics, who today is an instrument scientist with the ESI. “It’s been an explosion of not only the capacity of the group, but the science that we’re capable of doing.” 

“There’s huge power there”

“Because of its hyper-angular capability, there are things we can see with HARP2 that we have never seen before,” Martins explains. This includes new insights into cloud properties and aerosol types, which are critical for understanding climate and pollution. HARP2 also helps OCI see past atmospheric haze, boosting studies over land and water. 

HARP2 has been rock-steady since launch, with no major issues. It even uses the moon for monthly calibration checks to keep its data sharp. Designed for at least three years but with fuel for potentially a decade, it’s poised to keep delivering. The data is freely available, sparking discoveries worldwide. 

“HARP2 is helping us monitor and understand Earth’s systems and come up with ways to improve life,” Martins says.“We can study everything from fires to red tides and even floods, all the way from natural disasters to the effect of pollution on nature in general. There’s huge power there.” 

As the team celebrates HARP2’s more than 500 days in orbit, its steady stream of data continues to fuel discoveries that deepen our understanding of Earth’s atmosphere and oceans. From its roots as a small CubeSat to its role in NASA’s PACE mission, UMBC’s HARP2 showcases the power of collaboration among students, scientists, and NASA, driving science that informs everything from air quality forecasts to climate solutions. With years of potential ahead, HARP2’s impact is only beginning to unfold, inspiring new questions and innovations from UMBC’s campus to the global scientific community.

In 2020, as the COVID-19 pandemic disrupted lives worldwide,Greema Regmibegan her Ph.D. in UMBC’s atmospheric physics program. Studying remotely from her home in Nepal, she navigated a grueling schedule due to the time difference.

“One class started at 1 a.m. Nepal time, and one final went until 4:30 a.m.,” she recalls. Yet, she embraced the challenge. “I didn’t mind. I like working at night, so it worked for me. And because of COVID, I had nothing else to do. At least this way, I was making progress towards my studies.” 

Now in her fifth year, Regmi’s perseverance has earned her NASA’s prestigious Future Investigators in NASA Earth and Space Science and Technology (FINESST) fellowship, which will provide up to $50,000 annually for up to three years to fuel her research on atmospheric dust.

Regmi’s passion for atmospheric physics took root in Nepal. For an undergraduate project, she analyzed meteorological factors surrounding a tragic local plane crash. “Nepal has a lot of hills and mountains, so it channels wind in certain directions,” she explains. “Based on my analysis, unexpected turbulence could have been a factor in the crash.”

As a senior at Tribhuvan University in Kathmandu, Nepal, Regmi traveled to the U.S. for the first time, to present at the American Geophysical Union Annual Meeting. The event was a turning point in her scientific trajectory. 

“I really liked sharing my work in front of a huge crowd. Everybody was listening, and that boosted my confidence,” she says. In Nepal, it sometimes felt like research was a lower priority, but the U.S. offered a fresh stage for her work, Regmi says: “The AGU meeting was great—people appreciated my work. That was a huge motivation to continue and do grad school.”

Decoding dust for climate science

Regmi’s FINESST-funded research aims to improve the accuracy of climate forecasting by refining how atmospheric dust is accounted for in climate models. How dust scatters light affects how much heat is reflected back to space versus absorbed. She combines data from LiDAR and multi-angle polarimeters, such as NASA’s Research Scanning Polarimeter, to analyze dust’s role. 

“A polarimeter measures how much radiation you see from the top of the atmosphere,” integrating information from every atmospheric layer, “versus LiDAR, which gives you information on each layer of the atmosphere separately. So when you combine both of those, you have a very rich dataset,” she explains.

Regmi’s work challenges outdated assumptions. “Our existing models assume that dust has a simple shape, such as spherical, but for a long time we’ve known that it isn’t that simple,” she says. In her work, she models dust as hexahedral instead—a 3D shape with six faces. The most familiar hexahedron is a cube, but the angles can shift to make it more or less pointy. 

Regmi was surprised by how much using a spheroid versus hexahedral model for dust affects the overall climate models she is investigating. “I did not expect the shape of dust particles that tiny to have such a huge impact. And that was very exciting for me,” she says. 

Her research focuses on dust traveling across the Atlantic Ocean from the Sahara Desert. The solid, dark ocean background makes it much easier to pull out clean information about dust, avoiding uncertainty introduced by variegated background landscapes, like the shadows that form in mountain ranges or a wide range of vegetation colors. Improved climate models based on her work could inform decision-making related to climate resilience and mitigation.

A community that lifts you up

Regmi has been able to accomplish so much in part because of the supportive community she found at UMBC, after finally arriving on campus in fall 2021. Her Ph.D. advisor, Vanderlei Martins, professor of physics and director of UMBC’s Earth and Space Institute, fosters a collaborative lab. 

“Vanderlei is a great professor, but what I really appreciate about him is the group that he has built over years. Everybody in the group is as supportive as he is,” Regmi says. “He has done so much in the field, yet he’s still so humble.”

The positive feelings are mutual. “From the very first classes it was obvious that Greema had great potential and tremendous enthusiasm to learn, to grow scientifically, and to work with others,” Martins says.

Regmi is co-advised by Reed Espinosa, Ph.D. ’17, atmospheric physics, a research physical scientist at NASA Goddard Space Flight Center. “He is an outstanding mentor—patient, thorough, and always encouraging,” Regmi says. “Most of what I know about conducting research I have learned from him.” And Espinosa learned much of that from Martins, who was his own Ph.D. advisor. 

Pengwang Zhai, professor of physics, has been another mentor. “Regmi is a hardworking and intelligent student,” Zhai says. Despite starting her Ph.D. during the pandemic, “she embraced the difficulties, overcame steep learning curves, and has grown into a valuable member of the atmospheric physics program.”

Martins highlights her cohort’s strength. “Regmi has joined an enthusiastic group of Ph.D. students in the atmospheric physics program at UMBC, who have clearly shown that together we are better, and can go farther,” he says. 

Regmi values the camaraderie. “In Vanderlei’s group, people help you in every way they can,” she says. Her office near the elevator sparks connections. “Every time someone comes up, they will stop to say ‘hi.’ I’ve made a lot of friends and learned so much from them,” she shares. “I like my department a lot.”

Bridging two worlds

Regmi’s journey bridges her unique perspectives as a student in Nepal and the U.S. “You learn different things when you work back home in a developing country. And when you come here to a developed country, it’s a very different perspective,” she reflects. “In Nepal, it’s more about, ‘These are the resources we have, so how can we make the most out of them?’” she says. At UMBC, she’s embraced broader opportunities. “I think here you can push the limit. I don’t even know what the limit is in the U.S. Here you can dream more and be more experimental,” she observes.

Regmi is inspired by her father, also an atmospheric physicist, but she has forged her own path. This spring, she returned to Nepal for only the second time since starting her Ph.D. to conduct research with him. “I finally got to work with him professionally, which was great,” she says. 

Grounded in the UMBC physics department’s community of support, Regmi’s confidence has only grown since her arrival in Maryland. “There’s always a place for my opinion, which is very nice. Because of that, and all of the experiences I’ve had, now I have the confidence to start my own project,” she explains. “And that’s why I think now I’m confident to go back home, lead something there, and be helpful in some small way.”

UMBC is approaching 30 years of collaboration with the National Aeronautics and Space Administration (NASA), a partnership that largely culminates under the university’s three major cooperative agreements with the agency. According to the NSF’s latest Higher Education Research and Development (HERD) survey, UMBC is among the nation’s top 10 universities receiving federal funding from NASA. In 2024, UMBC scientists, researchers, interns, and engineers have reached new levels of achievement in connection to this partnership—some even going as far as to the surface of the Moon…in a few years. 

Take a look back at five ways UMBC collaborated with NASA in 2024:

UMBC goes to the Moon

Planetary scientist Mehdi Benna of UMBC’s Center for Space Sciences Technology is leading the team designing one of the lunar instruments chosen for implementation and deployment in NASA’s forthcoming Artemis III mission, humanity’s first return to the lunar surface in more than 50 years. The Lunar Environment Monitoring Station (LEMS) was selected as one of the first three candidate payloads to be a part of Artemis III, NASA’s mission that will send astronauts to explore the region near the lunar South Pole. Artemis III, currently planned to launch in 2026, will be the first time humans will return to the Moon’s surface since the historic Apollo program in 1969 – 1972. 

HARP2 launches into space

The UMBC-designed Hyper-Angular Rainbow Polarimeter (HARP2) wide-angle imaging polarimeter instrument is part of NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) spacecraft mission, which launched into space in February. The PACE satellite provides insight into ocean health, air quality, and the effects of a changing climate. PACE’s mission data, which includes data captured by the HARP2 instrument, is now available for public access. The HARP2 team, which includes a host of students and alumni, is led by Vanderlei Martins, professor of physics, who is also the director of the NASA-affiliated Earth and Space Institute, based out of UMBC’s Physics Building.

AXIS X-ray telescope selected for final round  

Nearly a year ago, a group of engineers and scientists including UMBC physicists became one of 10 teams to successfully submit a proposal to NASA to develop the Advanced X-ray Imaging Satellite (AXIS). In October 2024, the AXIS team was selected as one of the final two instrument designs selected for further development. The team will receive $5 million to flesh out their plans as part of what NASA calls a “Phase A study.” Adi Foord, assistant professor of physics, and Eileen Meyer, associate professor of physics, serve on the AXIS leadership team, and during the proposal development phase, Foord co-led the sub-team focused on supermassive black hole evolution.

NASA comes to campus

The university collaborated with the Goddard Space Flight Center to host the “NASA-UMBC Interaction Days,” an interactive, three-day series that took a closer look into the agency’s current research activity across a range of fields, with insight into how UMBC faculty, staff, and students can continue to work with Goddard scientists and engineers. The event series attracted more than 250 registrants. 

UMBC-NASA earth science center awarded $47 million extension

The UMBC-led Goddard Earth Science Technology and Research (GESTAR) II center was awarded a two-year, $47 million extension this year to continue its cooperative agreement with the NASA Goddard Space Flight Center (GSFC). Since launching in 2021, GESTAR II has employed more than 150 scientists who are distributed across nearly all of GSFC’s earth science division laboratories.  Over the years, GESTAR II researchers have been a part of teams that have developed an instrument that monitors water quality in the Chesapeake Bay, studied the environmental impacts of megafire smoke plumes, generated the first global map of cargo ship pollution, and much more. 

More on UMBC’s partnership with NASA

UMBC is collaborating with the NASA Goddard Space Flight Center (GSFC) to host an interactive, three-day event series that takes a closer look into the center’s current research activity, with insight into how faculty and students can engage with Goddard scientists and engineers. 

NASA-UMBC Interaction Days launched on September 9 and continues on September 16 and September 30, highlighting a range of topics on the diverse research and technological advancements in space exploration from leading scientists and engineers at GSFC. The series also provides an overview of the extensive research activity happening in collaboration between UMBC and NASA, a partnership that began nearly 30 years ago. 

Astrophysicist Sibasish Laha, an associate research scientist with UMBC’s Center for Space Sciences and Technology who works out of GSFC, organized the series in response to an influx of students inquiring about the work that happens at NASA and ways to get involved. 

“I started this interaction day series to help UMBC students better understand what NASA scientists and engineers do on a day-to-day basis,” says Laha. Students get a behind-the-scenes look into the research happening at GSFC, across an array of disciplinary fields such as earth science, data science and AI, astrobiology, and more.

Student opportunities at NASA

Day one of the event series included lectures focused on earth science, exoplanets, and laboratory astrophysics with featured speakers Maurice Leutenegger of GSFC’s x-ray astrophysics laboratory; Wayne Yu, an senior engineer in astrobiology; and planetary scientist Ravi Kopparap. A packed room of more than 90 attendees learned about the inquiring minds behind the GSFC’s research activity. 

Day two of the event series (happening on September 16) will feature discussions on data science and AI, x-ray astrophysics, and astrobiology. The event will conclude on September 30 with lectures on the habitable worlds observatory, payload systems and engineering, and NASA’s long term goals with featured speaker Robert Petre, director of GSFC’s astrophysics science division. 

Some Retrievers at the event were there out of general curiosity and some were looking for jobs and internship experiences. Brad Cenko, research scientist at GSFC, shared about the wide array of experiential learning opportunities happening at NASA’s research centers across the country.

“NASA has one of the largest internship programs in the state of Maryland, and students can apply to internships year-round,” said Cenko. This summer, UMBC students secured internship placements with NASA, which included senior Leah Narat, business technology administration, who worked at GSFC as a business intelligence intern. 

Narat created and updated databases to track awards given to NASA employees. The agency will use the information to maximize employees’ recognition and success and guide them toward career paths that best take advantage of their strengths. 

“Honestly, being at NASA was something that I never thought I would achieve, but I put my application out there, and here I am,” says Narat, who worked as a business intelligence intern at the NASA Goddard Space Flight Center in Greenbelt, Maryland, this past summer. “It’s been wonderful.”

A 30-year partnership

While a large majority of students made up the attendee list for day one, the event also brought in many faculty and staff interested in collaborating with the agency. “Faculty are an integral part in these collaborative efforts and our goal is to connect them directly with NASA’s scientists and engineers,” said event organizer Laha.

Currently, more than 250 UMBC scientists and research faculty members are partnering with NASA civil servants and are employed under three major cooperative agreements, of which includes the Goddard Earth Sciences Technology and Research II center (GESTAR II); the Center for Space Sciences and Technology (CSST); and the Goddard Planetary Heliophysics Institute (GPHI). The university also is home to the NASA-affiliated Earth and Space Institute based out of UMBC’s Physics Building. 

Additionally, nearly 30 of the university’s scientists and research faculty are working on active NASA space missions. That includes the UMBC-developed Lunar Environment Monitoring Station, which was selected as one of the first three instruments to be a part of Artemis III, NASA’s mission that will send astronauts back to the lunar surface after more than 50 years, and UMBC’s Hyper-Angular Rainbow Polarimeter wide-angle imaging polarimeter instrument on board NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem spacecraft mission. 

“NASA is providing half of UMBC’s federal contract funding—on a national scale, this is really unusual,” says Don Engel, director of the CSST and assistant professor of computer science and electrical engineering. “Our NASA partnerships are so cross-disciplinary. All three of UMBC’s colleges are represented with these centers, and that’s extremely significant.”

Register for the remaining NASA-UMBC Interaction Days events here.

Data from NASA’s newest Earth-observing satellite, which will provide insight into ocean health, air quality, and the effects of a changing climate, are now available. The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite launched on February 8, and after several subsequent weeks of testing of the spacecraft and instruments, the mission is gathering data that the public can access.

PACE includes three instruments: The Ocean Color Instrument (OCI), built at NASA Goddard Space Flight Center, observes the ocean, land, and atmosphere across more than 200 unique wavelengths spanning ultraviolet, visible, and near infrared light. It is particularly suited to identifying phytoplankton communities in the ocean. 

HARP2, designed and built by UMBC scientists and engineers, and SPEXOne, built at the Netherlands Institute for Space Research (SRON) and Airbus Netherlands B.V., are both polarimeters, which measure light that has reflected off clouds and particles in the atmosphere. These particles, known as aerosols, can range from dust to smoke to sea spray and more.

“First light,” as the first data received from satellites in orbit is known, is a key milestone in the progression of any scientific instrument destined for space.

“To me, first light means the conclusion of all the engineering work to develop HARP2 and the beginning of our science quest exploring and understanding the data from PACE,” shares Vanderlei Martins, professor of physics at UMBC and lead of the HARP2 team.  “First light means  ‘It is working!’ and the question right after first light is, ‘What does it mean?’”

Answering big questions about Earth’s interrelated systems

With data from PACE’s polarimeters, scientists will be able to measure cloud properties and monitor, analyze, and identify atmospheric aerosols to better inform the public about air quality. Scientists will also be able to learn how aerosols interact with clouds and impact cloud formation, which is essential to creating accurate climate models.

The HARP2 team will focus on air pollution, the effect of aerosols produced by humans on cloud formation, and the energy balance of the planet, Martins says. “We will learn about the type of aerosols in Earth’s atmosphere: What they look like in terms of size and shape matters in terms of their health effects,” he says. “The way they absorb and scatter light affects how they interact with solar radiation and influence the energy balance of the planet: Do they produce heating or cooling of the planet, and in which circumstances?”

“I have plans to use PACE aerosol and ocean products to better understand how nutrient-rich aerosols are deposited into the global ocean and how ocean plankton communities respond to this nutrient source,” adds Lorraine Remer, a UMBC climate researcher affiliated with the Goddard Earth Science Technology and Research Center II, one of UMBC’s NASA-partnered research centers.

First, though, “We will spend the next weeks and months tuning our parameters to coax out the most and best possible information on aerosols and clouds,” Remer says. “Then, the next step is to compare PACE’s output with established sensors on the ground.” A validation experiment in September 2024 called PACE-PAX will enable and encourage those comparisons.

PACE lets scientists put on “magical eye glasses”

Because of the power and unique capabilities of the instruments on PACE, “We see confident atmospheric parameters that have never been seen from any previous NASA mission,” Remer says. And because the data will be completely public, the benefits will go far beyond work that current PACE scientists will do.

“PACE data will be free for everyone around the globe and will be useful for decades to come,” Martins says. “Events on Earth will come and go, and they will be recorded forever by the PACE sensors. Beyond our own science studying aerosols, clouds, and the energy balance of the planet, this data will be explored by students and scientists for all sorts of applications that I can’t even imagine.” 

Martins expects UMBC scientists to write proposals to analyze PACE data for many years, and many of these projects will involve opportunities for students at all levels to gain experience with research. For now, PACE scientists are still relishing the successful launch and return of first light from the PACE instruments.

“When I look at the first light PACE images,” Remer says, “I feel like I have put on magical eye glasses and am seeing the true characteristics of aerosol plumes from a satellite for the first time.”

Jeremy Werdell, PACE project scientist, shepherded the project from start to finish, beginning when Martins pitched him the idea of including a HARP2-like instrument on board. “We’ve been dreaming of PACE-like imagery for over two decades. It’s surreal to finally see the real thing,” he says. “The data from all three instruments is of such high quality that we can start distributing it publicly less than two months from launch, and I’m proud of our team for making that happen.”

By Anne Wainscott-Sargent

The third time’s the charm. Against a calm and crisp dark night sky on Florida’s Cape Canaveral last Thursday, February 8, just after 1:30 a.m., the Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE) spacecraft rocketed to orbit carrying on board Hyper-Angular Rainbow Polarimeter (HARP2)―UMBC’s wide-angle imaging polarimeter.  The launch marked the first time NASA deployed a university payload on a large operational Earth science space mission.

Following two scrubbed night launches on Tuesday and Wednesday due to strong winds, Thursday’s successful takeoff was well worth the wait for the core team of UMBC Earth and Space Institute researchers, graduate students, and their family and friends who journeyed from Baltimore to watch the historic launch.

Arriving by bus a little before midnight to the Banana Creek Launch Viewing Area at Kennedy Space Center, just over six miles from Space Launch Complex-40, the close-knit UMBC entourage huddled together waiting for the final countdown.

When it came, they—along with hundreds of other space launch watchers—held their breath and then yelled and clapped as SpaceX’s Falcon 9 rocket blasted off and propelled PACE 400 miles above Earth into sun-synchronous orbit. Minutes later the Falcon 9’s first stage—SpaceX’s reusable rocket booster—successfully landed at Landing Zone 1. The crowd gasped audibly at the sonic boom, caused when the spacecraft broke the sound barrier.

“It still doesn’t quite feel real,” said Noah Christian Sienkiewicz, a calibration scientist who earned his master’s degree in atmospheric physics from UMBC in 2019 and expects to complete his physics doctorate this summer. “I grew up watching Carl Sagan and dreamed of going into astrophysics. I never thought I’d be the person making the instruments that will go up and do the measurements.”

“It’s so exciting—I’m going to cry,” uttered Margo Young from the upper bleacher. “I don’t always see the pieces and parts put together, so this is really historic.” 

Young serves as UMBC’s HARP program administrator, where she has overseen procurement and other back-end support for HARP since the program’s inception in 2013. “I get to see students come full circle—working in the lab and then graduating and becoming civil servants where they continue to be involved because it’s such an amazing project,” she explained.     

On the path to PACE

The UMBC HARP team’s remarkable journey from idea to mission reality spanned over 15 years, and involved countless hours of design, modeling, testing, and validation. Earlier iterations of HARP flew first on private aircraft over the Maryland countryside and then an award-winning “cubesat” version launched into orbit from the International Space Station (ISS), all stepping stones on the path to PACE.

For the three multidisciplinary HARP2 physics, optics, and research engineering leads, Vanderlei Martins, Roberto Borda, and Dominik Cieslak, HARP2’s launch represents a career-defining moment that at times seemed against all odds for a mid-size public university. UMBC’s strong partnerships with NASA, such as the Goddard Earth Science Technology and Research (GESTAR) Center II that supports Borda’s and Cieslak’s roles, help enable milestones like this.  

“I feel like I’m still dreaming,” said a visibly emotional Cieslak, research engineer, who captured the launch on his long-range camera. 

Transfixed by the sight of live satellite footage of the PACE spacecraft heading to orbit, he added, “This is the last time we will physically see it [HARP2],” before hugging his long-time colleague, Borda. 

“We’re very proud to have UMBC in space,” added Martins, professor of physics, who watched the big moment from a VIP viewing area three miles from the launch site. “We dreamed big from the beginning. The team persevered and just kept going.” 

“I never despaired of having HARP2 on the PACE satellite,” admitted UMBC’s HARP2 manager, Lorraine Remer, research professor in the Joint Center for Earth Systems Technology. Her bigger worry wasn’t HARP2’s viability, but whether PACE would ever launch. “PACE was canceled four times and reinstated four times,” she recalled, noting that the program “survived a lengthy government shutdown and a global pandemic that destroyed our supply chains.” 

Immediately after launch, Remer had to return to Maryland and the Goddard Space Flight Center to oversee HARP2 being turned on within 36 hours of launch. “It would be nice to bask in the successful launch, but I haven’t had much time to contemplate the success. There is just more work to do all the time,” she said.

An international effort

NASA’s PACE mission clears the path for revolutionary new measurements of Earth’s oceans and atmosphere. HARP2 measures aerosol particles and clouds, as well as properties of land and water surfaces. By analyzing particles like dust, wildfire smoke, or urban pollution, the science community gains deeper insights into air quality as well as global warming and its impacts. Scientists will be able see through things like sun glint to ascertain patterns never before possible.

A second polarimeter on PACE, the Spectro-polarimeter for Planetary Exploration (SPEXone), developed through a Dutch consortium consisting of SRON Netherlands Institute for Space Research and Airbus Defence and Space Netherlands, will measure sunlight reflected from Earth’s atmosphere, land surface and ocean.

These two companion polarimeter instruments are important because the interaction between aerosols and clouds is the biggest unknown factor in atmospheric temperature change, according to reports from the U.N.’s Intergovernmental Panel on Climate Change. 

“I have watched Dr. Martins and his team work toward this moment for about a decade, and have been aware of the trials and tribulations along the way. Seeing the smiles on their faces in the control station after the launch made it all worthwhile,” shared UMBC Vice President for Research Karl V. Steiner. “The HARP2 mission as an integral part of PACE is making all of us proud here on the UMBC campus. We cannot wait to see the science that will come from this engineering masterpiece conceptualized and created right here in Maryland.”

Waiting game

In the days leading up to the PACE launch, the HARP2 team knew there might be delays because of the weather so they rented a large Airbnb in neighboring Cocoa Beach for the full week. Earlier in the week, over grilled food at the shared house, the team reflected on their journey.

According to Martins, a key strategy was bringing together engineering and physics students, who typically don’t communicate well across disciplines.  

“We introduced engineering students to the physics students and made them work together very quickly so they spoke the same language,” he said, crediting this multidisciplinary collaboration to the team’s ability to rapidly iterate and problem solve.

Borda, senior research engineer overseeing HARP2’s optical design, said a key technical challenge was determining how to best compensate for the effects of polarized light waves inside the instrument.

“It’s continuous work and you cannot do it alone. We needed a fantastic team with not only the staff but also students working at different levels,” Borda said. “There are undergraduate students and Ph.D.s integrated into the team who put in a lot of effort to make this real. We’re really thankful for the environment at this university—we’re able to work with students who find a career in this industry and field of research.”

Nurturing future career scientists

Martins echoed Borda’s pride in the broad level of participation in the HARP program, from high school students to senior scientists.

“We’ve had people from our team who now work in all levels of industry—at NASA, at NOAA, or in private industry. We’ve even had some students start their own company.”

Young, the program administrator, estimates that the cooperative agreements between UMBC and NASA have resulted in 20 UMBC graduates finding roles with NASA.

UMBC alumna Elissa Ogburn is one such graduate. She began working on HARP2 as a computer science major, tasked with creating a database that supported ground communications so researchers could communicate with the instrument when it was in space.

After graduating from UMBC in 2021, Ogburn joined NASA on the PACE project as a test conductor (TC)―responsible for integrating and testing the instruments onto the PACE spacecraft. During launch, she was one of five TCs in the PACE Control Room in Titusville, Florida, who powered up the spacecraft for the last time and configured it for launch. 

“I never imagined having a job at NASA or working with people who were this smart, helpful, and kind. Every single person I’ve worked with was so fun. It’s also cool to have seen the whole process beginning as a student at UMBC. PACE is my first mission, so I’m learning everything as I go,” Ogburn said.

Close collaboration

The partnership between NASA and UMBC goes back over two decades. NASA Goddard Space Flight Center and UMBC are located just up the road from one another.

Jeremy Werdell, PACE project scientist at Goddard, recalled how initial calls to industry and academia for a polarimetry instrument for PACE were not promising due to cost and other factors.

However, Martins immediately suggested to Werdell that his lab develop a polarimeter, given his team’s experience with airborne instruments and the HARP cubesat, and the rest is history. In the end, NASA selected two polarimeters—HARP2 and SPEXone.

Each instrument measures polarization differently: HARP2 is multispectral (measuring only four wavelengths of light) and  hyperangular, so it looks at the same piece of real estate multiple times from dozens of different viewing directions. Its wide swath coverage means HARP2 will cover the globe every two days. SPEXone, on the other hand, is hyperspectral (measuring a continuous spectrum of light from the ultraviolet to near-infrared) but only views Earth at five angles. It has a narrower swath, meaning it will take almost a month to cover the globe. 

“They’re small and mighty and miraculously complement each other very, very well,” said Werdell. “Having multi-band, multi-angle polarimetry is going to open up a lot of really interesting opportunities for discovery, because we can see clouds and aerosols in very different ways.”

HARP2 provides daily views that will help scientists understand how aerosols and clouds interact and their role in warming and cooling in the atmosphere. 

“Understanding where aerosols are, how they’re transported, how they interact with clouds, and whether they absorb or reflect radiation is important to everybody because those characteristics are what drive warming of the atmosphere.” Werdell said.

Better air quality models 

Onsite at the Cape for the first launch attempts, Nirandi Jayasinghe and Rachel Smith, both physics graduate research assistants at UMBC, shared their excitement for the PACE mission and HARP2’s potential to help modelers predict air quality, rain, or if the atmosphere is warming or cooling. 

Jayasinghe is a data modeler who comes up with different methods to retrieve information from HARP2. Originally from Sri Lanka, Jayasinghe notes that her hometown used to be one of her country’s cleanest cities, and now due to development in Sri Lanka’s dominant neighbor, India, the air quality is extremely bad. She said HARP2 can help close the gap that exists in understanding the twilight zone—where a cloud starts and where it stops—by providing more accurate measurements. 

Smith adds that this will go a long way in understanding cloud formation processes, weather patterns, forecasting, and climate modeling—information important for agriculture, transportation, disaster preparedness, and infrastructure planning. 

“Even simple things like weather forecasting are impacted by how much dust is in the air,” said Smith, a 2026 doctoral candidate who earned her M.S. in atmospheric physics from UMBC in 2023. HARP2 will help address whether clouds have a net cooling effect or a net warming effect, which will allow for more accurate models of where Earth’s climate is headed. Smith notes that during events like the Canadian wildfires in 2023 no one could accurately predict rainfall, because the forecasting models were not accounting for the number of airborne aerosols.

“I’m really excited to see what new science questions come out of the instruments that we’re putting up in space,” she concluded.

Bouncing back from disaster 

The HARP2 team has come a long way from initial concept to PACE. What impresses Werdell the most is the UMBC team’s resilience in the face of setbacks.

The most devastating moment came in February 2022, one month before the team was set to deliver HARP2 to NASA for integration on the spacecraft. As the instrument was in the last few seconds of vibration tests, the bonding on one of the prisms loosened and shattered. 

“It tactically put us to point zero,” recalled Cieslak, who was shocked and humbled when so many NASA scientists volunteered their time and expertise to help the HARP2 team get back on track. 

“We got an extension, and within two months we had built a new engineering model and were able to prove the new solution worked. By September, we were back to where we were before the incident,” he added.

First-time NASA launch attendee Yomiyu Fekadu ’20, mechanical engineering, M.S. ’23, engineering management, recalled that time well, as he helped assemble HARP2 as an intern under Benjamin Cramer ’17, M.S. ’20, mechanical engineer on the program.  

“Especially after the failure, and the review board assessment, I helped put everything back together and do the test plans for construction and other documentation so NASA could give us the go-ahead to move on,” Fekadu said. 

The experience was pivotal to his career. “It was everything I could have asked for,” said Fekado, now a systems engineer at Northrop Grumman. “No other place would have let me be involved in the entire process, including making parts for HARP2 in the machine shop. Not only did I get to do hands-on stuff, but I also was part of the design and saw it all come together on a NASA mission.”

As the HARP2 group left the viewing platform to line up for bus rides back to the Space Center, the smiles and easy camaraderie conveyed a collective sense of pride, relief, and excitement. 

“I‘m now just anxious to see the first bytes of data,” said Cieslak, echoing the feeling of his colleagues.

In addition to the HARP team, several additional GESTAR II scientists and engineers were instrumental in their contributions  to the overall PACE mission, including Ivona Cetinić, Andrew Sayer, Violeta Sanjuan Calzado, Bridget Seegers, Susanne Craig, Dirk Aurin, Meng Gao, Inia Soto Ramos, and Ian Carroll.

Update: On February 10, HARP2 successfully connected with instrumentation on the ground and all of its systems appear to be working as intended. 

Follow along with what’s learned from the HARP2 project.

The first Hyper-Angular Rainbow Polarimeter (HARP) was a nano-satellite about as big as a loaf of bread. Developed by Vanderlei Martins, professor of physics, and his team of scientists and engineers at UMBC’s Earth and Space Institute, the HARP cubesat launched to the International Space Station in November 2019 and was released into orbit in February 2020. HARP spent over two years collecting first-of-its-kind data on Earth’s atmosphere, and finally deorbited in April 2022. 

But that was just the beginning. Soon, HARP2 will be part of NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission. And the HARP team is preparing now to compete for a spot on the future NASA Atmosphere Observing System (AOS) mission as MegaHARP.

From the HARP cubesat, “We have data now on clouds. We have data over the ocean. We have data over land surfaces in a way that we never had before,” Martins says. The instrument was so impressive that the American Institute of Aeronautics and Astronautics named it SmallSat Mission of the Year in August 2021. “Now,” Martins says, “we are using HARP data to develop algorithms and methodologies that we will use for these other missions.”

Proving it works

On its 27-month flight, HARP’s unique sensors collected new kinds of information about clouds and tiny particles in Earth’s atmosphere, such as wildfire smoke, desert dust, and human-generated pollutants. These particles, collectively known as aerosols, have many effects on the global climate and the health of organisms. The data may inform refined climate models or strategies to reduce the effects of air pollution.

HARP also broke ground in the way it collects data. HARP captures images, but “it’s not a camera that takes pictures. It’s something a lot more sophisticated,” Martins explains. “It’s taking thousands of these pictures and recombining them in a way that becomes a multi-dimensional scientific data set.”

A single composite image generated by HARP can contain the information from up to 1,000 original images. Each image and its information are extractable from the composite, which allows researchers to look at many different parameters depending on their goals. 

“The HARP cubesat allowed us to prove that the idea we had of how to create the composite images worked,” Martins says.

Opening the path

HARP’s physical design is also innovative. A single instrument with no moving parts houses the sensors and algorithms used to process all the different data types. That’s a big benefit for any instrument facing the harsh environment of space.

“For us, HARP was a pathfinder,” Martins says. “It was funded as a technology demonstration. So we launched HARP to demonstrate that this technology is possible, and to open the path for other missions that are coming after that.”

HARP2 is already taking advantage of lessons learned from HARP. It will fly on NASA’s PACE mission in 2024, but the team must deliver their instrument to the Goddard Space Flight Center this October.

“HARP2 is basically an advanced copy of the instrument payload in the HARP cubesat,” Martins says. Everything from calibration systems to the raw materials has undergone improvements. 

Plus, due to greater availability of technical resources on the larger PACE mission compared to the original cubesat, Martins explains, “HARP2 in five hours will collect as much data as HARP cubesat collected in two years.”

Launching satellites and careers

Since its inception, HARP has also lived up to UMBC’s mission to educate students and support the regional economy and workforce. Undergraduate and graduate students played key roles in the research, design, and construction phases for HARP and now HARP2.    

“Relationships with federal agencies like NASA, all the work that we do with private companies around us, plus the training of students, who then go on to lead the same field they were working in, all fit very well the goals of our public research university,” Martins says.

Through HARP, HARP2, and early preparation for MegaHARP, every iteration of the project has prepared students for successful careers, proven new technologies, and generated new knowledge about the world. But, as an educator, perhaps the most rewarding part for Martins is seeing his students grow, find success, and then reach back to help others.   

“We are seeing with HARP a full cycle. Students were involved in the inception of the idea for HARP from the beginning,” he says. “And today, students who were there working on HARP at the beginning are now in positions at NASA supporting the next generation.”

Noah Sienkiewicz is working alongside NASA and UMBC colleagues to design and build HARP2, an instrument that will launch on NASA’s PACE mission in 2024. Nathan Myers is partnering with top scientists across the country at Los Alamos National Laboratory in New Mexico on innovative quantum computing research. And both physics Ph.D. students have just received highly competitive grants that will help them take their work even further. 

Myers received an Office of Science Graduate Student Research award from the U.S. Department of Energy (DOE), which will fund an 11-month experience at Los Alamos. Sienkiewicz received a Future Investigators in NASA Earth and Space Science and Technology (FINESST) Fellowship, which will fund his Ph.D. thesis work at UMBC for up to the next three years.

Fresh ideas

Myers is looking forward to infusing fresh ideas from Los Alamos scientists into his research on non-linear quantum systems. His work fits into the field of quantum thermodynamics, which is critical to the future of computing. The non-linear quantum systems he explores have the potential to be much faster than the already super-fast linear quantum systems that researchers have modeled and begun to fabricate.

Myers had already planned to pursue this area of research, but “now we’ll have the resources and the collaboration with all the researchers at Los Alamos, which is one of the foremost quantum computing research centers in the U.S.,” he says. “So it’s pretty exciting.”

Begin with the end in mind

Sebastian Deffner, assistant professor of physics and Myers’s mentor, has gone the extra mile to make sure he is in a strong position for the future. In addition to supporting his students’ research, Deffner also helps his mentees develop “related skills, in terms of how to write and apply for these funding opportunities, awards, and grants, and just how to build your network and get in contact with people,” Myers says.

In fact, “When I was first starting research,” Myers says, “one of the first conversations we had was, ‘So, when you graduate, what are some of the places where you might be interested in working? And who can we talk to, to start that process as early as possible?”

Los Alamos was on Myers’s list. Deffner connected Myers with Yigit Subasi, a Los Alamos scientist, and their conversation revealed significant overlap between their research interests. They were coming at the same questions from different angles. So, they collaborated on the proposal for the DOE funding to blend their ideas and work on a breakthrough together.

“Winning this award will give Nathan a unique opportunity to interact with and learn from world-leading experts at a top-tier research location,” Deffner says. “The potential impact on his scientific career can hardly be overestimated, and I hope that this will set a new benchmark for the excellence of our graduate education at UMBC.”

The full arc

Sienkiewicz started his UMBC career in a research rotation with Zhibo Zhang, associate professor of physics. He then rotated to work with Vanderlei Martins, professor of physics and director of UMBC’s Earth and Space Institute, who is now his Ph.D. advisor. Zhang gave Sienkiewicz an introduction to computational techniques. And with Martins, he learned how to apply those techniques to data that address the most fundamental physics describing an instrument or phenomenon.

Those two experiences informed Sienkiewicz’s path forward. Now he wants to be involved in “the full arc” of atmospheric research projects— “to make sure the whole process is interconnected and well-informed,” starting with design, and progressing through testing and data processing.

These days, Sienkiewicz is working on both HARP2 and the original HARP, which he helped develop before it launched successfully in fall 2019. In the morning, he analyzes incoming HARP data. Then, in the afternoon, he uses what he observed to inform decisions about HARP2. Both instruments have the potential to inform how climate models account for clouds and tiny particles in the air called aerosols, such as dust, smoke, and other airborne chemicals.

“My goals are to straddle that line between someone who runs code all day and someone who goes into the lab and does the testing,” Sienkiewicz says. It’s a rarer path among atmospheric physicists, but one that offers exciting opportunities. In particular, Sienkiewicz’s comprehensive perspective will be beneficial in the planning process for NASA’s next decade, he believes.

A childhood dream

Both HARP and HARP2 are examples of polarimeters, which will be a major focus of NASA experiments over the next 10 years. Sienkiewicz hopes to stay involved in their development after he graduates, in 2023 or 2024, by transitioning to a role at NASA proper just in time for the PACE mission launch that will carry HARP2 into space.

Through UMBC’s strong connections with the space agency, “I’ve gotten to be more exposed to actual NASA work, and sit in meetings with NASA officials,” Sienkiewicz says. “So, as far as the childhood dream of ‘I want to work for NASA,’ I feel like it’s been a great stepping stone to doing that and having direct interaction with those people and building a network.”

Support at every level

With Sienkiewicz focused on space and climate science and Myers on quantum computing, their physics research could hardly be farther apart. But they actually have a lot in common.

Sienkiewicz and Myers began their graduate studies at UMBC at the same time. “We sat shoulder to shoulder in the first-year grad student office in 2017,” Sienkiewicz says. “Especially in that first year, our whole cohort really stuck together and helped each other a lot.”

They became friends and housemates. Even as their research trajectories diverged, living in the same house during a pandemic exposed them to each other’s work in new ways. “I’ve probably learned more about quantum thermodynamics in the last year than I ever have, because I hear him in the other room going on and on about anyons,” Sienkiewicz says with a smile.

Their personal camaraderie speaks to a larger graduate student support network in physics at UMBC. For both Myers and Sienkiewicz, the application process for their awards was a group effort, with multiple rounds of feedback from faculty, peers, and staff at UMBC’s Joint Center for Earth Systems Technology (JCET).

In addition to the DOE award, Myers is also funded by the private sector arm of NASA, Paraton, and benefits from a National Science Foundation grant awarded to Deffner. Sienkiewicz received a Graduate Assistant in Areas of National Need award from the U.S. Department of Education in his first year, and, later, a JCET fellowship. 

“Getting the funding opportunities through UMBC and making those connections has been instrumental to my progress,” Sienkiewicz says. “Our department really supports students by keeping them funded and showing them opportunities. They help set us up for success.”

UMBC’s Hyper-Angular Rainbow Polarimeter (HARP) Satellite, which began in Vanderlei Martins’s imagination more than a decade ago, has been flying in low-Earth orbit since February 19. It contains new technology that can collect detailed information about tiny particles in the atmosphere—previously unmeasurable data that will inform climate studies for years to come. The HARP team, including a large number of students, overcame obstacles at every step of the satellite’s journey to space, and its success is already being recognized.

On August 6, the American Institute of Aeronautics and Astronautics (AIAA) named HARP the Small Satellite Mission of the Year. To qualify as a “smallsat,” satellites must weigh less than 150 kg (330 lbs.). To win, a smallsat must demonstrate significant improvement in the capability of small satellites. That could mean advances in their structural design, scientific instrumentation, communications ability, or other factors.  

A popular vote informed the AAIA SmallSat Technical Committee’s final decision. After voters selected HARP as a finalist, the smallsat went up against nine other finalists, including teams from the U.S., Guatemala, Singapore, and France. Votes for HARP poured in from all over the world, including ballots from 40 states and countries on six continents. In the end, HARP emerged as the winner.

A moment of joy

“I would like to thank the HARP team as a whole, because HARP is really the result of the perseverance of the team over many years,” said Martins, director of UMBC’s Earth and Space Institute, as he accepted the award. “There has been no shortage of problems, but we have always worked together to overcome them.”

HARP’s innovative design and ability to collect new kinds of data that will be crucial for future research sealed the win. The HARP instrument, designed and built by a UMBC team and funded by the NASA Earth Science Technology Office, is smaller than a loaf of bread. Yet, its pioneering polarimeter (the first ever in orbit) can measure certain properties of particles in the atmosphere for the first time, offering a new look at the properties of clouds and tiny particles in the atmosphere called aerosols. The first observation from HARP arrived back on Earth on April 16, and it’s been collecting data continuously since. 

The small spacecraft developed by UMBC’s partners at Space Dynamics Lab (SDL) carried HARP to space, and the SDL team manages the satellite while it is in orbit. The whole satellite (instrument plus spacecraft) is the size of a large loaf of bread and only weighs about 6 kg (13 lbs.). UMBC shares the award with Space Dynamics Lab, which is affiliated with Utah State University.

“All of us at UMBC are so very proud of the efforts and the impact of Vanderlei Martins and the Earth & Space Institute,” says Karl Steiner, UMBC’s vice president for research. “Looking back at the launch of the HARP satellite at Wallops Island this past November, I know that today’s recognition as SmallSat Mission of the Year brings a much-needed moment of joy and encouragement to our campus community during a very different time.”

Student-driven success

The AIAA also gave out a People’s Choice Award (PCA) at the ceremony. The awards committee selects a PCA when a project has made substantial, unique contributions, but doesn’t necessarily meet the requirements for Mission of the Year. This year, Quetzal 1, Guatemala’s first-ever satellite, received the People’s Choice Award. Quetzal 1 has “opened the whole field of space science and technology in Guatemala,” shared Emily Clemens, awards committee chair.

Guatemala currently has no engineering graduate school programs and no space agency, noted Luis Zea, one of Quetzal 1’s co-directors, “but the students here accomplished something that I think is a good example of what young people can do when they set their minds to solving problems.”

Students are at the root of HARP, as well. The team has included scientists and engineers at every level. High school students, undergraduates, and graduate students all made important contributions in collaboration with faculty researchers.

“HARP is a small satellite, but we always had very big ambitions,” Martins says. At long last, those ambitions are bearing fruit. Some of the students who worked on HARP, and some new ones, are now at work on HARP2, which will build on technology developed for HARP. HARP2 will travel on the major NASA PACE mission, scheduled to launch in 2023. HARP2 will collect data that will inform studies of air quality, clouds, precipitation, and climate.  

With only a tinge of disbelief, and a big smile, Martins says, “And that’s all due to this small satellite.”

On the third floor of the UMBC Physics Building, a glass sign with crisp white lettering announces UMBC’s newest research center: the Earth and Space Institute (ESI).

The institute includes a prototyping lab, operations center, and offices, but it is also much more than a collection of rooms, explains Karl Steiner, UMBC’s vice president for research. The ESI is a physical home for the interdisciplinary earth and space science UMBC researchers do with support from NASA, NOAA, and other federal agencies as well as collaborators around the world. It’s a hub where scientists, engineers, and students will take UMBC’s earth and space research to the next level.

The ESI, administered by UMBC’s College of Natural and Mathematical Sciences (CNMS), joins a set of other distinguished UMBC research centers, including the Center for Space Science and Technology (CSST), Goddard Planetary and Heliophysics Institute (GPHI), and Joint Center for Earth Systems Technology (JCET), all of which are collaborations with the NASA Goddard Spaceflight Center in Greenbelt, Maryland.

CNMS Dean Bill LaCourse believes NASA has served as “a role model and inspirational force,” that has led people to reach for the stars for generations, and he is excited to expand UMBC’s collaborative work with NASA. “The Earth and Space Institute is our opportunity to reach for new heights,” he shares. “To take that chance in the name of science, commitment, passion, and basic human curiosity.”

At a ribbon cutting for the new space, leaders from the three other centers, as well as the director of NASA Goddard, gathered to discuss current projects and ideas for future collaborations. They emphasized the strong and ongoing relationship between UMBC and NASA, which is only expected to deepen with the dedication of the new institute.

“It’s great to be here. The partnership with UMBC is just fantastic,” said NASA Goddard director Christopher Scolese. “All this happens because of the strength of your work, and we should say thank you to all of you,” added UMBC President Freeman Hrabowski, speaking to the scientists in the room. “It takes researchers to produce researchers.”

Vanderlei Martins, professor of physics and director of the new institute, describes the ESI as a place “to develop new technologies and new science in earth and space fields.” Martins is currently working on HARP, a CubeSat mission intended to launch within the next year. But he and other UMBC scientists have their eyes on an ever bigger goal: a full-blown NASA mission with their equipment on it. The ESI will make planning and successfully proposing such a mission a real possibility.

Another important aspect of the institute is its role as a platform to boost collaboration across disciplines. “We want to collaborate even more with Goddard on the engineering side, on the science side, on the education side,” says Martins, noting that this could mean pulling in faculty and students at all levels and from a broad range of focus areas.

Jane Turner, director of CSST, shares that “one of our important roles is to connect our graduate and undergraduate students to mentors and project opportunities at Goddard”—a goal the new ESI shares. Lorraine Remer, a JCET research professor, adds that recruiting UMBC students to careers at NASA or other federal agencies via experiences with UMBC collaborative centers could also play a role in diversifying the federal workforce, because of UMBC’s strong track record for supporting the success of students from all backgrounds in STEM fields.

Alan Yeakley, chair of geography and environmental systems, also envisions opportunities for the ESI to utilize the social sciences in its work. “I see geography and environmental science as the connective tissue between the natural sciences and the social sciences,” he shares. Data collected by NOAA satellites, for example, can contribute to public health research on air quality, urbanization, and the effects of climate change.

The ESI is intended to bring the UMBC community together in new ways, just as it came together to support the institute’s creation. “It takes a community—a wide spectrum of people giving support from all kinds of directions—to bring something like this together,” LaCourse says. From the crews that renovated the space to university administrators at the highest level, “There has been cross-campus support… This is a university facility that was a feat to get off the ground, and now it’s here.”

“The Earth and Space Institute leverages our resources and expands our potential,” LaCourse says. Inspired by NASA, “it allows UMBC to dream bigger and reach higher.”
