Bente Eegholm is an optical engineer working to ensure missions like the Nancy Grace Roman Space Telescope have stellar vision. When it launches by May 2027, the Roman mission will shed light on many astrophysics topics, like dark energy, which are currently shrouded in mystery. Bente’s past work has included Earth-observing missions and the James Webb Space Telescope.
Name: Bente Eegholm
Title: Goddard Optics Lead for Roman Space Telescope OTA (Optical Telescope Assembly)
Formal Job Classification: Optical Engineer
Organization: Optics Branch (Code 551)
Bente Eegholm stands by the NASA’s Nancy Grace Roman Space Telescope’s primary mirror at L3Harris in Rochester, New York, in 2022, before telescope integration. (The black lines are resistor wires. They will be obscured by the secondary mirror struts). NASA/Chris Gunn What do you do and what is most interesting about your role at Goddard?
I am an optical engineer, and I work on the Nancy Grace Roman Space Telescope as the Goddard optics lead on the observatory’s OTA (Optical Telescope Assembly). My work is a combination of optical systems work, technical meetings, and hands-on work in the labs and integration facilities. The most interesting part is that we are creating unique, one-of-a-kind instruments, which enable NASA, as well as anyone around the world, to become more knowledgeable about our universe, including our own planet.
How will your current work influence the Nancy Grace Roman Space Telescope’s future observations?
The quality of Roman’s future observations is directly tied to the telescope’s optical quality. As an optical engineer I am involved with providing the best imaging possible for the telescope and its science instruments. I work closely with the OTA management, and optical and system engineers at Goddard and at L3Harris in Rochester, New York, a mission partner that is building the OTA. The OTA consists of a series of total 10 mirrors. I am frequently on site in Rochester, most recently for the very important first light test and ensuing alignment process of the telescope. We are striving to get every photon possible delivered to Roman’s two instruments, the WFI (Wide Field Instrument) and coronagraph technology demonstration.
What motivates you as an engineer? And what was your path to your current role?
It motivates me to support a great purpose, pioneer technology for spaceflight, and to conquer the challenges that inevitably occur along the way. I also enjoy being a mentor for newer engineers, as well as giving Roman tours and presentations to Goddard visitors.
I received my M.Sc. and Ph.D. degrees in my native Denmark. The path to my current role really started in 2004 after I had obtained my green card and gotten a position with Swales Aerospace, supporting NASA Goddard’s Optics Branch, Code 551. I was a contractor for eight years, supporting the James Webb Space Telescope. This was a magnificent project to work on; it was very rewarding in terms of the optical technology to accomplish this mission, as well as the amazing and talented people with whom I was working. I supported the development and test of a speckle interferometer which we used to prove the stability of the backplane structure for Webb’s primary mirror.

I was appointed the ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope product development lead for the ICESat-2 mission, an Earth-observing mission to measure sea ice thickness from space. Both a flight and a spare telescope were built, and after successful testing and delivery of the ATLAS flight telescope, the ATLAS spare telescope was a perfect match for GEDI (the Global Ecosystem Dynamics Investigation), a mission to measure forest canopies from the International Space Station. That naturally led to me to continue to GEDI, where I was the alignment lead. GEDI launched in December 2018.
In 2019 I started working on the Roman Space Telescope and was thrilled to work on a large astronomy mission again, and in two capacities to boot. Concurrently with my role on the telescope I was optics lead on the prism assembly (a slitless spectrometer which helps enable the WFI’s study of dark energy) from 2019 until its completion and delivery to the WFI in September 2022.
I feel very fortunate to have experience from both astronomy and Earth-observing missions! It definitely widens your technical experience. Often, the telescopes and science instruments for astronomy missions typically take longer to develop and implement than the ones for Earth-observing missions. With the shorter time to launch, you have the opportunity to see the fruits of your labor fly into space within a few years, and it is beneficial to go through the steps of an entire development and launch cycle.
How do you stay updated on the latest technological advancements? How do you apply that knowledge to your work?
I enjoy learning something new every day, either by individual research or via professional organizations. I use it in my own work and in working with many optics vendors, and being a reviewer on projects and proposals. Bringing new technology to Goddard is important, and we must approve each technology for space flight before we can use it in our next missions.

That is a really hard question. Just like you can’t choose between your children! All four of the missions I have worked on have been awesome experiences. A recent amazing event, though, was on Roman, watching the first fringes emerge on the OTA interferometer screen at the “first light” session in the integration facility. This was the result of several years of hard work for many people, and it indicated that all the 10 telescope mirrors were well-positioned, boding well for the successful final alignment, which we achieved.
What do you like best about working for NASA?
I enjoy working on unique projects, always reaching for the stars, and using new technology and methods. NASA is a unique organization, known by everyone around the globe. For example, it has been a great honor to hear from many people who follow our work how much they appreciate Webb. NASA’s work is very visible, and that commits us and holds us accountable. And we are up to the challenge!
What hobbies fill your time outside of work?
I love yoga, and hiking in nature. I also love singing in choir, especially classical music. The magnificent sound we can achieve with 75 singers, and how the different types of voices merge to convey the music, is an example of collaboration that is a bit like succeeding in a flight mission. All the different people, tasks and parts synchronized and coming together to make it work!
What advice do you have for others who are interested in working in engineering?
Maybe I am a bit biased, since both my husband and I are engineers, my son is in grad school for engineering, and my daughter is in grad school for ocean science. In my opinion, an engineering degree offers highly transferable skills, and is a great path for everyone who enjoys math and physics. People skills are also important in engineering, as most projects are performed in teams. Make sure to select math and science classes in high school, and aim for internships in college. An engineering degree requires effort and dedication, but it’s worth it!

NASA Stennis Autonomous Systems Laboratory Project Engineer Travis Martin monitors successful data delivery from the center’s ASTRA payload aboard the orbiting Sidus Space LizzieSat-1 satellite. The ASTRA autonomous systems hardware/software payload represents the first-ever in-space mission for NASA Stennis. NASA/Danny Nowlin NASA’s Stennis Space Center and partner Sidus Space Inc. announced primary mission success July 2 for the center’s historic in-space mission – an autonomous systems payload aboard an orbiting satellite.
“Our ASTRA (Autonomous Satellite Technology for Resilient Applications) payload is active and operational,” NASA Stennis Center Director John Bailey said. “This is an incredible achievement for Stennis, our first-ever in-space mission flying on a new state-of-the-art satellite. We are all celebrating the news.”
ASTRA is the on-orbit payload mission developed by NASA Stennis and is an autonomous systems hardware/software payload. The NASA Stennis ASTRA technology demonstrator is a payload rider aboard the Sidus Space premier satellite, LizzieSat-1 (LS-1) small satellite. Partner Sidus Space is responsible for all LS-1 mission operations, including launch and satellite activation, which allowed the NASA Stennis ASTRA team to complete its primary mission objectives.
LS-1 launched into space on the SpaceX Transporter 10 rideshare mission March 4 and deployed the same day. The LS-1 satellite commissioning began after deployment and was completed on May 12. Sidus Space’s next step was to begin activation of payloads, including ASTRA.
After the payload was activated, the NASA Stennis Autonomous Systems Laboratory (ASL) team confirmed they had established a telemetry link to send and receive data in the ASTRA Payload Operation Command Center. The ASL team continued to checkout and verify operation of ASTRA and has confirmed that ASTRA primary mission objectives have been successfully achieved.
“This is just a remarkable and inspiring accomplishment for the entire team,” said Chris Carmichael, NASA Stennis ASL branch chief. “So many people put in a tremendous effort to bring us to this point. It is a great demonstration of the team’s vision and capabilities, and I am excited to see what the future holds.”
The NASA Stennis ASL works to create safe-by-design autonomous systems. ASTRA demonstrates technology that is required by NASA and industry for upcoming space missions. The ASTRA computer on the satellite runs a digital twin of satellite systems, which detects and identifies the causes of anomalies, and autonomously generates plans to resolve those issues. Ultimately, ASTRA will demonstrate autonomous operations of LS-1.
“Achieving ASTRA’s primary mission objectives underscores our dedication and commitment to driving innovation while advancing space technology alongside NASA, our trusted partner,” said Carol Craig, Founder and CEO of Sidus Space. “We are proud to support such groundbreaking projects in our industry and eagerly anticipate the continued progress of our LizzieSat-1 mission.”
The success of the ASTRA mission comes as NASA Stennis moves forward with strategic plans to design autonomous systems that will help accelerate development of intelligent aerospace systems and services for government and industry.

On June 21, three days before crew egress, about 200 people gathered at Space Center Houston’s theater for a live Q&A session where students had the opportunity to share their questions with crew members Al Romaithi and Wijesekara. They discussed team dynamics, adapting to unexpected circumstances, and coping with isolation.
When asked about what prompted her to apply for the mission, Wijesekara emphasized the importance of helping NASA collect data that could help future long-duration space flights, saying, “This will be very useful when we get to the Moon with Artemis missions and even beyond that when we go to Mars.”

When a student asked about building stronger teams, Wijesekara advised, “Spend time with your crewmates, get to know them deeply, and be a good listener.”
Al Romaithi, who hails from the UAE, shared that his academic background in aerospace engineering and aviation helped him stand out in the application process. In addition, this HERA campaign is focused on cultural diversity, which opened the opportunity for him to apply through a partnership between HERA and MBRSC.
Discussing the mental effects of isolation, Al Romaithi highlighted the comfort provided by personal items, books, and board games. Wijesekara noted that the white noise of instruments running became their constant companion that her senses adjusted to over time.
Wijesekara told the audience her favorite experience was performing spacewalks and “flying drones on Mars,” via virtual reality, which allowed them to observe Martian landscapes and even lava caves. Through the habitat’s window screens, they could see simulated views of space and Martian landscapes.
The crew addressed the challenges they faced inside the analog environment, such as communication delays, which taught them teamwork, patience, and precise planning. They utilized a 3D printer aboard HERA to address equipment issues. A curious student asked what happens to the crew and the mission in case of an outside emergency, like a hurricane. Both crew members explained that HERA provided them with step-by-step emergency instructions.
Medical evaluations and nutrition-specific meal plans were crucial for the mission, Al Romaithi and Wijesekara noted, with daily monitoring of the crew’s physical and mental health. The crew also grew lettuce hydroponically and had four pet triops shrimp named Buzz, Alvin, Simon, and Theodore.
When a student asked what food he missed most, Al Romaithi replied, “Home-cooked meals.”
Wijesekara shared the first thing she plans to do post-mission is see her family and visit a list of restaurants with her crewmates. She also looks forward to running on the beach.
Reflecting on their experience, Al Romaithi noted, “We’ve become more disciplined and efficient in our daily activities.”
What was the most valuable lesson learned? “The importance of teamwork and communication,” he said.
Both crewmembers also gave students in the audience some advice. “Never hesitate or be shy to ask for help,” Al Romaithi said. “Always push for your biggest dreams, don’t let self-doubt slow you down, and believe in yourself.”
“And keep studying!” added Wijesekara.

Mapping the Red Planet with the Power of Open Science
This image of Perseverance’s backshell sitting upright on the surface of Jezero Crater was collected from an altitude of 26 feet (8 meters) by NASA’s Ingenuity Mars Helicopter during its 26th flight at Mars on April 19, 2022. NASA/JPL-Caltech Mars rovers can only make exciting new discoveries thanks to human scientists making careful decisions about their next stop. The Mars 2020 mission is aimed at exploring the geology of Jezero Crater and seeking signs of ancient microbial life on Mars using the Perseverance rover. Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Southern California used novel mapping techniques to direct both the rover and the flights of the Ingenuity helicopter, which rode to Mars on Perseverance — and they did it all with open-source tools.
JPL mapping specialists Dr. Fred Calef III and Dr. Nathan Williams used geospatial analysis to help the scientific community and NASA science leadership select Jezero Crater as the landing site for Perseverance and Ingenuity. Before the vehicles arrived on Mars, they helped create maps of the terrain using data from orbiting satellites.
“Maps and images are a common language between different people — scientists, engineers, and management,” Williams said. “They help make sure everyone’s on the same page moving forward, in a united front to achieve the best science that we can.”
Maps and images are a common language between different people.

NASA JPL Geologist and Systems Engineer
After the mission touched down on Mars in February 2021, the Ingenuity helicopter opportunistically scouted ahead to take photos. The team then generated more detailed maps from both rover and helicopter image data to help plan the Perseverance rover’s path and science investigations.
To enable this full-scale mapping of Mars, Calef created the Multi-Mission Geographic Information System (MMGIS), an open-source web-based mapping interface. Online demos of the software, pre-loaded with Mars imagery taken from orbit, allow visitors to explore the paths of Perseverance, Ingenuity, and the Curiosity rover, a sister Mars mission that landed in 2012.
This image of NASA’s Perseverance Mars rover at the rim of Belva Crater was taken by the agency’s Ingenuity Mars Helicopter during the rotorcraft’s 51st flight on April 22, 2023. The rover is in the upper left of the image, parked at a light-toned rocky outcrop. NASA/JPL-Caltech The open nature of the software was key to the mission’s success. “We have people literally all over the world who are working on the mission, and we need to be able to give them fast and quick access to software and data,” Calef said.
MMGIS aimed to help people understand the full scope of Martian geography. By combining images from orbit and augmenting with images from Perseverance and Ingenuity, the JPL team allows researchers to zoom in to see individual boulders and zoom out to see all of Mars. This variety of viewpoints gives the team a sense of scale and context to properly understand the landscape around the Perseverance rover, and how to optimally achieve their science goals within the available terrain.
This image of an area the Mars Perseverance rover team calls “Faillefeu” was captured by NASA’s Ingenuity Mars Helicopter during its 13th flight at Mars on Sept. 4, 2021. Images of the geologic feature were taken at the request of the Mars Perseverance rover science team, which was considering visiting the geologic feature during the first science campaign. NASA/JPL-Caltech The impact of the tools developed by the JPL team went beyond the Mars 2020 mission. The team wanted their software to help other researchers easily visualize their data without needing to be data visualization experts themselves. Thanks to this open-source approach, other teams have now used MMGIS to map Earth and other planetary bodies.
In keeping with this open philosophy, the images taken by Perseverance and Ingenuity over the course of the Mars 2020 mission are freely available to the public. By sharing these data with the rest of the world, the results from the mission can be used to educate, inspire, and enable further research.
It’s being able to share data between people … getting a higher order of science.
Fred Calef
NASA JPL Geologist and Data Scientist
As Mars scientists look to the future, with the Perseverance rover team deploying even more advanced tools powered by AI, open science will pave the way for further exploration. JPL is now working on designs for potential future Mars helicopters that are far more capable and complex than Ingenuity. Payload mass, flight range, and affordability are at the forefront of their minds.
Existing open-source tools will help address those concerns. Not only are open-source applications free to use, but the large amount of collaboration in creating and testing them means that they’re often highly reliable.
Ultimately, the JPL team views its work as part of the cycle of open science, using open tools to make its job easier while also developing new features in the tools for others to use in the future. “Every mission is contributing back to the other missions and future missions in terms of new tools and techniques to develop,” Calef said. “It’s not just you working on something. It’s being able to share data between people … getting a higher order of science.”
