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. 

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.

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.

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.

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.

Nominate yourself or a colleague to join the leadership council of the NASA AI/ML Science and Technology Interest Group (STIG). We welcome early-career researchers (graduate students, postdocs, and early-career scientists) broadly interested in AI and astronomy. Duties are light: suggesting speakers and helping run remote seminars by sending reminders and introducing the speaker.

https://docs.google.com/forms/d/e/1FAIpQLSc5ccFmCWEw-fDmkjlldeUvSK81f6M_2DauycSif3GN3rw9tw/viewform

As we begin planning the next iteration of the NASA Artificial Intelligence and Machine Learning Science and Technology Interest Group (AI/ML STIG) seminar series, we are expanding our leadership council and would love your help. We are writing to invite you to nominate yourself or a colleague to join.

We are especially looking for early-career researchers, including graduate students, postdocs, and early-career scientists, who are broadly interested in the intersection of AI and astronomy. You do not need to be an expert across the whole field; curiosity and a willingness to help the community learn matter most.

The organizational duties are light. Council members help suggest speakers and run the remote seminars, which mainly means sending email reminders and introducing the speaker. It is a great way to meet people across the field and to help shape a series that reaches the NASA community and beyond.

Two themes will anchor next year’s series:

1. Agentic AI for Astrophysics. How LLM agents and multi-agent systems can accelerate astronomical research, from literature and data analysis to simulation and discovery workflows.
2. AI and Astronomy in the US: Initiatives, Funding, and Broader Impacts. The wider landscape of AI in astronomy, including national initiatives, funding opportunities, AI pedagogy, the ethics and philosophy of AI in science, and ways AI can support NASA priorities such as ASTRA.

Please use this Google form to nominate yourself or someone else by the end of next week (extended to 27 June 2026).
