Why and Where Do We Want to Put Telescopes on the Moon?
Speaker
Nivedita Mahesh, CU Boulder
Abstract
The Moon is emerging as a uniquely valuable platform for astrophysics, enabling observations that neither Earth nor free-flying spacecraft can support. This talk surveys the scientific motivation across four complementary regimes. At low radio frequencies, the radio-quiet lunar farside opens a window onto the cosmological Dark Ages and the magnetospheres of exoplanets. In the mid-band gravitational-wave regime, the Moon’s low seismic activity bridges the sensitivity gap between terrestrial and space-based detectors. At ultraviolet wavelengths, its natural vacuum and long coherence times allow high-resolution stellar imaging beyond what is possible on Earth. And in the far-infrared, the cold, stable conditions of permanently shadowed regions offer a naturally cryogenic, absorption-free site for probing star and planet formation and the obscured Universe.
For each regime, I will share updates from the mission concept leads on the efforts now developing within the Astrophysics from the Moon, Mars & Beyond (AMMB) Science Interest Group. Together, these cases point to a paradigm shift: astrophysics from the Moon is becoming not just desirable but necessary.

Abstract
Cosmic Origins Science covers a broad range of topics that are fundamental to our understanding of the evolution of structure in the Universe and the physical processes that can explain the formation of galaxies, stars, and planets that we observe today. The various space telescopes that operate across the electromagnetic spectrum have been crucial to address some of the most fundamental questions related to our cosmic origins. The landscape of Space Astronomy is evolving fast with innovative technology, industry partnerships, and new commercial launch capabilities. In this talk, I will review the Cosmic Origins Program and discuss the new opportunities that offer strategic pathways for focused-science missions.
Ad ASTRA Workshop Abstract and Mission Concept Deadline Extended to 1 July 2026
23 June 2026
Dear Astrophysics Strategic Technology & Research Accelerator (ASTRA) community members-

Ad ASTRA Workshop
The deadline for abstract submission for the Workshop has been extended to 1 July 2026.
Submit workshop abstracts via the workshop webpage. If you have already submitted an abstract and would like to modify it based on the guidelines above, please delete your previous contribution and send another submission. Note while talks will be focused on science and technological capability themes, we encourage participants to present their mission concepts as posters, and will offer the opportunity to present as posters any abstracts for which there is insufficient room in the parallel sessions.
ASTRA Mission Concepts
The deadline for submitting ASTRA Mission Concept Documents has also been extended to 1 July 2026.
The most recent decadal survey in Astronomy and Astrophysics (released in late 2021) identified the most compelling science goals, presented a program of ground- and space-based activities for future investment, and recommended critical actions to support the foundations of the profession as well as the technologies and tools needed to carry out the science. At the request of NASA, NSF, and DOE, this midterm assessment reviews progress towards the priorities from the decadal survey.
The National Academies of Sciences, Engineering, and Medicine (the National Academies) shall convene an ad hoc committee to review the responses of NASA’s Astrophysics program, NSF’s Astronomy program, and DOE’s Cosmic Frontiers program (hereafter the Agencies’ programs) to previous National Academies advice, primarily the 2020 National Academies decadal survey, “Pathways to Discovery in Astronomy and Astrophysics for the 2020s” (Astro2020).
The committee’s review will include the following tasks:
Scientific and Technical Landscape: Identify and evaluate the most significant scientific discoveries, technological advancements that could impact implementation, changes to the facilities landscape, and relevant programmatic changes in astronomy and astrophysics since the publication of Astro2020.
Alignment with Decadal Priorities: Assess the extent to which the programs of the relevant agencies align with the strategies, goals, and priorities outlined in Astro2020 and other pertinent National Academies reports in the context of the Agencies’ current strategic priorities and budgets thus far allotted to them.
Recommendations for Maximizing Scientific Return: Considering 1 – the advice provided since the publication of Astro2020 by any Federal Advisory Committees active at the time, 2 – the Agencies’ strategic plans, and 3 – the mid-decade contingencies described in the decadal survey, recommend actions that maximize the scientific return of the Agencies’ programs.
Foundational and Enabling Activities: Evaluate progress and alignment with recommendations on foundational activities, including workforce development, technology maturation, and data infrastructure.
Consideration of International Partnerships and Cross-Agency Opportunities: Assess opportunities to advance the implementation of priorities outlined in Astro2020 that are presented by changes in international partnerships and cross-agency cooperative capabilities.
The review should not revisit or alter the scientific priorities or mission recommendations provided in the decadal survey and related National Academies reports but may assess progress in implementation of the recommended science and activities portfolio and on other potential activities in preparation for the next decadal survey.
Rohit Goeptar, an electromagnetic/radio frequency analyst with NASA’s Launch Services Program at the agency’s Kennedy Space Center in Florida, reviews a radio frequency link budget analysis for NASA’s Nancy Grace Roman Space Telescope from his office. Goeptar is among the engineers and technicians sworn in as new NASA civil servants as part of NASA Administrator Jared Isaacman’s workforce directive to restore technical core competencies within the civil servants ranks.

Rohit Goeptar was born into a poor family in Suriname, South America, the kind where both parents work three jobs and they still can only provide food and shelter for their family. At around age six, his family moved to California to start a new life. Only two years later, he moved back to South America with his father while his mother stayed in the United States and remarried. When he was 13, he became a U.S. citizen and he and his brothers returned to live with their mother in California.
At 19, Goeptar joined the U.S. Marine Corps where he spent six years as a technical operator. During one deployment to the Philippines, Goeptar helped set up communication systems for individuals who needed to contact their loved ones after a typhoon ripped through entire towns.
“I was lost, the Marine Corps gave me an opportunity,” Goeptar recalled.
While the Marines taught him useful skills, his life had not been the easiest. He lost not one, but two, fathers to suicide, and a short first marriage ended with him being unhoused on the streets of Kissimmee, Florida, for six months. But Goeptar eventually found his way.
As with most underdog stories, there was another person in the shadows behind his rise to success.
“Your brain works in mysterious ways,” his now wife told him a short while after they met. She then filled out college applications for him, and he eventually applied to NASA’s Kennedy Space Center in Florida.
While raising three kids, going to school full-time pursuing a computer engineering and electrical engineering degree simultaneously, Goeptar got the call that changed his life.
“In spring 2025, I was driving to pick my son up from school when a gentleman from Kennedy calls, telling me he’s seen my resume and do I have time for a quick interview,” Goeptar recounted.
He pulled on the side of the road and took part in an impromptu job interview.
Two weeks later, he had an in-person interview with others from Kennedy and two weeks after that, he had a contractor badge at America’s premier spaceport.
After starting as an intern under the Expendable Launch Vehicle Integrated Support, or ELVIS, contract, then moving to part-time until he graduated from the University of Central Florida (UCF) in Orlando, then full-time at the beginning of 2026, Goeptar was one of the ELVIS contractors who applied and were picked up to become civil servants recently.

NASA/Amanda Griffin
Now an employee of NASA’s Launch Services Program, Goeptar works with electromagnetic interference, electromagnetic compatibility, and radio frequency. It is his job throughout the entirety of the mission to analyze and ensure avionic boxes or anything electrically powered doesn’t interfere with any other systems. He also ensures independent systems are compatible when brought together. And finally, he conducts model radio frequency link analysis for different rockets and science demonstrations payloads. These may belong to NASA or commercial partners, and he is responsible for ensuring uninterrupted communication with the ground. In his short time at Kennedy, Goeptar has worked on Sentinel-6B, JPSS-4 (Joint Polar Satellite System), and IMAP (Interstellar Mapping and Acceleration Probe) missions.
And as far as his wife’s assessment that his brain works differently, he proved that within a year at Kennedy when he noticed an analytical issue his team wasn’t tracking. Once a rocket launches, it does a pitch, yaw, and roll. The analysis the team had been conducting didn’t account for this movement, which meant it wasn’t as accurate as it could be. He presented his solution to the team lead, and it now enables NASA data and partner data to be much more in sync.
“There is no greater feeling, being able to serve. It’s more than serving the public, it’s serving our country. It’s serving the future of our country,” Goeptar said with tears brimming in his eyes. “Being able to give back to that same government that gave me an opportunity to be where I’m at today. There’s no greater feeling than that.”
Meanwhile, Goeptar’s 11-year-old takes most of the credit for his landing at the space center, a NASA enthusiast, his son believes he spoke it into existence.

“One day he wants to become an astronaut,” Goeptar said with joy on his face. “And I told him I will guide him until the day that I die. Maybe my last mission could be the one my son flies on. I’m not going to stop until that day happens.”
Rohit’s positive streak continues as he recently was accepted into electrical engineering master’s programs at both Johns Hopkins University, and UCF.

Developed at NASA’s Jet Propulsion Laboratory, ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain) is used in a desert field test to help refine mobility hardware and autonomy software that could be used for a potential future long-range lunar rover mission.
During the field test, which took place in March 2026 in the Colorado Desert of Southern California, the JPL team deployed ERNEST at all times of the day — including dusk, dawn, and nighttime, when lighting conditions create long shadows like those seen on the Moon’s polar regions.
On a bleak stretch of the Colorado Desert in Southern California, a compact four-wheeled rover recently trundled about 16 miles (26 kilometers) with minimal intervention from the team of engineers trailing it. Called ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain), this prototype is being used by NASA to advance both robotic autonomy and the ability to traverse challenging landscapes.
Developed at NASA’s Jet Propulsion Laboratory in Southern California, ERNEST is 4 feet (1.2 meters) long. Not only can it lift each of its mesh wheels to get past obstacles that would stymie Curiosity and Perseverance, NASA’s six-wheeled Mars rovers, but the prototype also has enhanced independent decision-making capabilities. These mobility and autonomy advances could be infused into future missions that will venture to previously inaccessible areas of the Red Planet or the Moon.
ERNEST serves as a testbed for a potential future lunar rover mission requiring high speeds and extreme distances. In a recent field test, the prototype traveled 16 miles over the course of 37 hours, going an order of magnitude above the top speed at which NASA’s current Mars rovers can navigate.

In the field, ERNEST served as a testbed for a potential future lunar mission requiring higher speeds and much greater mileage than can be accomplished by current rovers. This technology could be used to inform future designs for exploration efforts on the Moon and beyond.
“This testing is helping us refine the mobility hardware and autonomy software to navigate extreme distances across a wide range of terrain and lighting conditions anticipated on the Moon,” said Issa Nesnas, a principal technologist at JPL who led the recent testing as head of autonomy for a NASA mission concept for a potential future long-range lunar rover.
Engineers from JPL set up illuminators after transporting ERNEST for a pre-sunrise test during a seven-day desert field campaign.
NASA/JPL-Caltech
Nesnas’ team is using ERNEST to demonstrate it is possible to build a rover that’s twice as big as the prototype and capable of a long-distance Moon mission. During the recent campaign, ERNEST traveled at speeds up to 0.6 mph (1 kph) over 37 hours of driving, across seven days of intermittent testing. That’s an order of magnitude above the top speed Perseverance and Curiosity can navigate.
“You could do a science road trip across the Moon — or Mars — with this vehicle,” said James Keane, a JPL planetary scientist working on lunar missions.
The initial goal of the team that developed ERNEST was mechanical: to design a relatively simple, low-cost rover that advances the trusted rocker-bogie suspension system featured on every Mars rover since NASA’s Sojourner. This passive system keeps relatively constant weight on all six wheels, thanks to pivot points and struts that enable each one to adapt to the changing surface.

On ERNEST, the active suspension lets the rover manage weight distribution among its wheels. Two powered joints in front articulate a gimbal that allows the rover to drive using different gaits like squirming, wheel-walking, and obstacle-climbing. With a clutch mechanism, it can switch between active and passive suspension, which is less terrain capable but more energy efficient. With four steerable wheels, it can drive in any direction, including sideways.
“We started by postulating that we could do better in designing a planetary surface robotic mobility system,” said Hari Nayar, a JPL principal technologist leading the ERNEST team. “While the rocker-bogie system has been very successful over the past 30 years, there’s been a lot of research in that time on mobility and understanding terrain interaction.”
Before arriving at today’s version of ERNEST, the team built two earlier prototypes, each about 2 feet (0.6 meters) long, to test 11 active suspension configurations. In a trailer filled with lunar regolith simulant, they ran experiments at different slope angles over several months before landing on a final design.
Then the team scaled up, including adding a rectangular head mounted on a 4.5-foot-tall (1.4-meter-tall) mast. The hardware was completed in September 2024, but the rover still needed a human operator to joystick it, sending commands to instruct the rover on how to move over obstacles.
In order to train the rover to think on its own, the ERNEST team turned to reinforcement learning, a type of artificial intelligence where the robot learns by interacting with its environment. The Dynamics and Real-Time Simulation Laboratory at JPL developed a high-fidelity virtual testing environment that replicates the rover’s behavior. The team fed the simulator data collected by engineers who documented the response of the actual rover hardware to a variety of terrain types. On a high-performance computing cluster, the team ran many simulations at once, sometimes completing thousands of hours of tests over a single weekend.
After months of virtual training, the ERNEST team was ready to see if the rover could use its new autonomous algorithms to figure out how to drive over terrain features that would halt a passive-suspension rover. They set up an obstacle course with sand ripples, rubble piles, steps, and steep slopes in JPL’s Mars Yard, an outdoor terrain proving ground. Then they watched as the rover maneuvered the terrain on its own. Since then, ERNEST has completed many such courses.
Nayar’s team is starting a new autonomy project which involves integrating the rover’s ability to determine when and how to use its active suspension with longer-range intelligent navigation. The goal is to enable ERNEST to plan an efficient path so that it can tackle surmountable obstacles and circumnavigate hazardous ones. These capabilities could contribute to potential future rover missions encountering formidable landscapes on Mars or more rugged areas of the Moon.
Work on ERNEST began in 2022 was initially supported by JPL internal research and development funds. It is currently funded by NASA’s Mars Exploration Program and the agency’s Exploration Science Strategy and Integration Office in its Science Mission Directorate at NASA Headquarters in Washington. Caltech in Pasadena, California, manages JPL for NASA.

The 248th Meeting of the AAS
The 248th AAS meeting (joint with the High Energy Astrophysics and the Laboratory Astrophysics Divisions) will be held 14-18 June 2026 in Pasadena, California.
NASA’s Center of Excellence for Collaborative Innovation (CoECI) assists in the use of crowdsourcing across the federal government. CoECI’s NASA Tournament Lab offers the contract capability to run external crowdsourced challenges on behalf of NASA and other agencies.
Sponsored by the Administration for Strategic Preparedness and Response (ASPR), a division of the U.S. Department of Health and Human Services (HHS), this prize competition seeks forward-thinking solutions to strengthen the nation’s ability to rapidly produce and distribute critical medical supplies during public health emergencies and supply chain disruptions. Through three challenge phases, participants will develop an innovative conceptual systems design using technologies and frameworks that advance the future of resilient medical manufacturing, logistics, and digital coordination capabilities.
Phase 1: Participants will submit:
8-page submission paper
3-minute Pitch video
Blueprint supporting the key capabilities and structure of the solution
Submissions will be evaluated per challenge Judging Criteria. Following the Judge evaluation period, up to 8 Finalists will receive a $5,000 prize each and be invited to the hybrid (in-person and virtual) Pitch Event at ASPR headquarters in Washington, DC. Up to 3 Winners from the Pitch Event will receive a $150,000 prize each and be invited to the innovation development phase.
Phase 2: Two developmental milestones will monitor solution development and will include $75,000 additional prizes for each milestone complete (up to $150,000 in total milestone prize payments).
Phase 3: At the end of the development milestone period, up to 3 teams may be invited to the final Live Validation Event to test their solution under applicable real-world simulations and compete for a total prize purse up to $1,100,000.
