Developed by NASA’s Glenn Research Center in Cleveland together with Voyager Technologies, the Lunar-g Combustion Investigation (LUCI) will help researchers determine if conditions on the Moon – with reduced gravity – might be a more hazardous environment for fire safety.
The video shows a plastic rod and cotton-fiberglass fabric being burned during a ground test of the Lunar-g Combustion Investigation (LUCI) experiment. Scientists will compare the ground test video to the video recorded on the Blue Origin flight.

NASA Blue mach diamonds from the main engine nozzles and bright exhaust from the solid rocket boosters mark the successful launch of space shuttle Endeavour 25 years ago on Feb. 11, 2000. The STS-99 mission crew – including astronauts from NASA, the National Space Development Agency of Japan (NASDA), and the European Space Agency (ESA) – were aboard the shuttle.
This mission saw the deployment of the Shuttle Radar Topography Mission mast and the antenna turned to its operation position. After a successful checkout of the radar systems, mapping began less than 12 hours after launch. Crewmembers split into two shifts so they could work around the clock.
Also aboard Endeavour was a student experiment called EarthKAM, which took 2,715 digital photos during the mission through an overhead flight-deck window. The NASA-sponsored program lets middle school students select photo targets and receive the images via the Internet.

Jesse Walsh helps to bring people together in his work with project formulation management. “I try to build trust between team members by understanding everyone’s incentives and making sure all team members understand the different incentives,” he said. “We may have different angles of approach, but we all have the same goal.”Credits: NASA’s Goddard Space Flight Center/William Hrybyk Name: Jesse Walsh
Formal Job Classification: Project Formulation Manager
Organization: Project Formulation and Development Office, Flight Projects Directorate (Code 401.0)
What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
As a formulation manager, I am the project manager in the room as we are designing science space flight missions. We develop proposals to be competed on the agency level against other NASA centers, and outside institutions.
I am also our office’s representative on the Earth science line of business.
“I help everyone negotiate a balance that fits within the cost and schedule,” said Walsh. “The diversity between and among scientists, engineers, and financial experts is what creates NASA’s innovative solutions.”Credits: NASA’s Goddard Space Flight Center/William Hrybyk What is your background?
In 2000, I graduated from the U.S. Naval Academy with a B.S. in mechanical engineering. In the Navy I went to flight school in Pensacola, Florida, and became a naval flight officer. I was the “Goose,” not “Maverick,” in the P-3 Orion, a four-engine prop plane that primarily hunts for submarines. I was then stationed in Hawaii as part of Patrol Squadron 9, that deployed to the Far East and Middle East. Next, I worked at the Naval Research Lab in Washington, D.C., as a project officer for science experiments on P-3s from Patuxent River Naval Air Station in Patuxent River, Maryland.
I developed migraines that disqualified me from flying. In 2007, I got a master’s in civil engineering project management from the University of Maryland. I then worked in Bethesda, Maryland, constructing buildings around the beltway, as a physics teacher at our local high school, and as a project manager of secure facilities with the Army Corps of Engineers.
In 2016, I became the assistant branch head for facilities planning at Goddard. I later entered the Flight Projects Development Program, a two-year project manager training program, during which time I worked at the Flight Projects Development Office and as the payload manager for Space Infrastructure Dexterous Robot (SPIDER), a payload on OSAM-1. I had a proposal selected for a second step, and I came back to PFDO to work proposals.
Why is this your dream job?
We are on the cutting edge of what will fly. We are designing the missions and figuring out what the world of possible will be in space in five to seven years. Scientists come to the table with ideas and engineers make those ideas reality. I make sure the whole team is working together and that all these ideas and solutions fit within our budget and schedule. We make ideas realities.
How do you translate between scientists and engineers?
It is primarily about understanding incentives. Everyone is thinking differently with different solutions, but we have the same goal. Some scientists have had an idea for years, but the idea still has to be workable. If the resulting instrument or spacecraft fails, technical issues are often the first to be examined. I help the engineers push what they are comfortable making and help the scientists understand the limits of technology.
Please talk about the competing pressures of your job.
We are responsible for taxpayer’s money. If one thing goes wrong, even on a smaller mission, the monetary loss can run into many millions. The missions we build have cost limits. We fit cutting edge science into a cost-limited opportunity.
NASA is extremely thorough. We safeguard taxpayer funds, but also push cutting-edge science.
We are on a seesaw. The engineers are more focused on technical solutions while the scientists are more focused on scientific results. I help everyone negotiate a balance that fits within the cost and schedule. The diversity between and among scientists, engineers, and financial experts is what creates NASA’s innovative solutions.

I try to build trust between team members by understanding everyone’s incentives and making sure all team members understand the different incentives. We may have different angles of approach, but we all have the same goal. People are more likely to compromise the means if they know we will end up at the same place.
What is your proudest accomplishment?
I am proudest of our Dorado proposal because it was cutting edge science. We were trying to discover where heavy metals like gold are created in the universe. We were trying to prove that we could do fundamental science on a very lean budget, $35 million.
We did not win the final proposal, but I was extremely proud of our team, a very small, high-functioning team, that made us feel like we could discover the world.
You recently transferred to support the Geospace Dynamics Constellation (GDC) mission. What do you most enjoy about your new role?
I am still learning what I don’t know about GDC. I am finding is fascinating to see how the plans that are made in early stages of formulation change and adapt as they run into unforeseen obstacles during implementation. I am really enjoying being part of a small, high performing team, that is mission focused.

I married a librarian, and books and stories are fundamental parts of our life. I love Hemingway because he portrays extremely complex, emotional scenarios in very simplistic terms.
Who is your science hero?
My high school physics teacher, Mr. Finkbeiner, who taught me that you understand science in your gut, not your head. Science is not memorizing equations; it is understanding how the world around you works.
What are your hobbies?
I love flyfishing on the Chesapeake’s tidal rivers and also on fresh water for trout. Flyfishing involves actively engaging with nature; reading the water and the tides, figuring out nature’s puzzle and trying to crack the code.
What is your “six-word memoir”? A six-word memoir describes something in just six words.
I can’t wait for what’s next!

Video: 00:01:20 Listen to the ESA/JAXA BepiColombo spacecraft as it flew past Mercury on 8 January 2025. This sixth and final flyby used the little planet's gravity to steer the spacecraft on course for entering orbit around Mercury in 2026.
What you can hear in the sonification soundtrack of this video are real spacecraft vibrations measured by the Italian Spring Accelerometer (ISA) instrument. The accelerometer data have been shifted in frequency to make them audible to human ears – one hour of measurements have been sped up to one minute of sound.
BepiColombo is always shaking ever so slightly: fuel is slightly sloshing, the solar panels are vibrating at their natural frequency, heat pipes are pushing vapour through small tubes, and so forth. This creates the eerie underlying hum throughout the video.
But as BepiColombo gets closer to Mercury, ISA detects other forces acting on the spacecraft. Most scientifically interesting are the audible shocks that sound like short, soft bongs. These are caused by the spacecraft responding to entering and exiting Mercury's shadow, where the Sun's intense radiation is suddenly blocked. One of ISA's scientific goals is to monitor the changes in the ‘solar radiation pressure’ – a force caused by sunlight striking BepiColombo as it orbits the Sun and, eventually, Mercury.
The loudest noises – an ominous ‘rumbling’ – are caused by the spacecraft's large solar panels rotating. The first rotation occurs in shadow at 00:17 in the video, while the second adjustment at 00:51 was also captured by one of the spacecraft’s monitoring cameras.
Faint sounds like wind being picked up in a phone call, which grow more audible around 30 seconds into the video, are caused by Mercury's gravitational field pulling the nearest and furthest parts of the spacecraft by different amounts. As the planet's gravity stretches the spacecraft ever so slightly, the spacecraft responds structurally. At the same time, the onboard reaction wheels change their speed to maintain the spacecraft's orientation, which you can hear as a frequency shift in the background.
This is the last time that many of these effects can be measured with BepiColombo's largest solar panels, which make the spacecraft more susceptible to vibrations. The spacecraft module carrying these panels will not enter orbit around Mercury with the mission's two orbiter spacecraft.
The video shows an accurate simulation of the spacecraft and its route past Mercury during the flyby, made with the SPICE-enhanced Cosmographia spacecraft visualisation tool. The inset that appears 38 seconds into the video shows real photographs taken by one of BepiColombo's monitoring cameras.
