NASA Tech Contributes to Soft Moon Landing
For the first time in more than 50 years, new NASA science instruments and technology demonstrations are operating on the Moon following the first successful delivery of the agency's CLPS (Commercial Lunar Payload Services) initiative.
Intuitive Machines' Nova-C lander, called Odysseus, completed a seven-day journey to lunar orbit and executed procedures to softly land near Malapert A in the South Pole region of the Moon at 5:24 p.m. on Feb. 22. The mission marks the first commercial uncrewed landing on the Moon.
NASA and Intuitive Machines co-hosted an afternoon news conference Feb. 28 from the agency's Johnson Space Center. NASA+, NASA Television, and the agency's website will provide updates.
Carrying six NASA science research and technology demonstrations, among other customer payloads, all NASA science instruments completed transit checkouts en route to the Moon. A NASA precision landing technology demonstration also provided critical last-minute assistance to ensure a soft landing. As part of NASA's Artemis campaign, the lunar delivery is in the region where NASA will send astronauts to search for water and other lunar resources later this decade.
"For the first time in more than half a century, America returned to the Moon. Congratulations to Intuitive Machines for placing the lunar lander Odysseus carrying NASA scientific instruments to a place no person or machine has gone before, the lunar South Pole," said NASA Administrator Bill Nelson. "This feat from Intuitive Machines, SpaceX, and NASA demonstrates the promise of American leadership in space and the power of commercial partnerships under NASA's CLPS initiative. Further, this success opens the door for new voyages under Artemis to send astronauts to the Moon, then onward to Mars."
During the journey to the Moon, NASA instruments measured the quantity of cryogenic engine fuel as it has been used, and while descending toward the lunar surface, teams collected data on plume-surface interactions and tested precision landing technologies.
New lunar science, technology
NASA's Navigation Doppler Lidar for Precise Velocity and Range Sensing (NDL) guidance system for descent and landing ultimately played a key role in aiding the successful landing. A few hours ahead of landing, Intuitive Machines encountered a sensor issue with their navigation system and leaned on NASA's guidance system for an assist to precisely land. NASA's instrument operates on the same principles of radar and uses pulses from a laser emitted through three optical telescopes. It measures speed, direction, and altitude with high precision during descent and touchdown.
NASA instruments focused on investigating lunar surface interactions and radio astronomy. The Odysseus lander also carries a retroreflector array that will contribute to a network of location markers on the Moon for communication and navigation for future autonomous navigation technologies.
Additional NASA hardware aboard the lander includes:
- Lunar Node 1 Navigation Demonstrator: A small, CubeSat-sized experiment that will demonstrate autonomous navigation that could be used by future landers, surface infrastructure, and astronauts, digitally confirming their positions on the Moon relative to other spacecraft, ground stations, or rovers on the move. LN-1 was developed, built, and tested at NASA's Marshall Space Flight Center.
- Laser Retroreflector Array: A collection of eight retroreflectors that enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The array is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come.
- Radio Frequency Mass Gauge: A technology demonstration that measures the amount of propellant in spacecraft tanks in a low-gravity space environment. Using sensor technology, the gauge will measure the amount of cryogenic propellant in Nova-C's fuel and oxidizer tanks, providing data that could help predict fuel usage on future missions.
- Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath: The instrument will observe the Moon's surface environment in radio frequencies, to determine how natural and human-generated activity near the surface interacts with and could interfere with science conducted there.
- Stereo Cameras for Lunar Plume-Surface Studies: A suite of four tiny cameras to capture imagery showing how the Moon's surface changes from interactions with the spacecraft's engine plume during and after descent.
NASA is committed to supporting its U.S. commercial vendors as they navigate the challenges of sending science and technology to the surface of the Moon.
"In daring to confront one of humanity's greatest challenges, Intuitive Machines created an entire lunar program that has ventured farther than any American mission to land on the Moon in over 50 years," said Steve Altemus, CEO of Intuitive Machines. "This humbling moment reminds us that pursuing the extraordinary requires both boldness and resilience."

Black History Month Profile: Joseph Gaines on Endurance
By Celine Smith
Joseph Gaines joined the U.S. Army Reserve while he was a student at the University of Memphis in Tennessee. But there was one hitch - as a reservist he was stationed in Mobile, Alabama, more than 350 miles away from the school.
So, each Sunday after Gaines finished his drills at 4 p.m., he made the six-plus hour commute from Mobile to Memphis to attend his 8 a.m. class the following Monday.
"It was rough," Gaines said, briefly laughing at the memory. "Of course, that was a lot of sacrifice."
Gaines joined the Army Reserve to financially support his education. Gaines' dedication to his education reflects the effort and work ethic still present with him after 34 years with NASA's Marshall Space Flight Center. It's also a reflection of the values his mother instilled in him.
"She's my biggest influence," Gaines said. "She was a single parent taking care of two boys, while attending night school and working a full-time job."
Along with his mother, Gaines said his high school math teacher, Melton McMullan, had an immense influence on him. McMullan constantly told Gaines he had what it took to become an engineer after noticing his strength in the subject.
While Gaines majored in electrical engineering at the University of Memphis, he could not have imagined a career with NASA. "I was so enamored with NASA, but I didn't even think I had the opportunity to work there," Gaines said.
His stance changed in one day.
"I was a junior sitting in my power systems class," Gaines said. "A senior walked in wearing a suit, so I asked him where he came from. He told me an interview and I asked with who. He said NASA and then told me where the interviewer was."
Gaines left during the middle of class and headed for his dorm room. He changed clothes, grabbed his resume, found the interviewer, and got an interview. Two weeks later, he was juggling a NASA co-op role while also in the Army Reserve, all while completing his degree.
Thirty-four years later, Gaines is the manager of Marshall's Safety and Quality Assurance Department. He ensures the continuous improvement of safety by overseeing industrial safety and pressure systems, along with quality assurance for the center and its contracted industrial activities.
"I really enjoy making sure that Marshall has quality flight hardware and a safe work environment while doing so," Gaines said.
His journey at Marshall began with Frank Nola, an esteemed engineer who taught him everything about circuits while he was in control systems during his co-op. "It was fascinating," Gaines said. "I developed a lot of skills and confidence working with senior level engineers in my early career."
After graduating in 1989, Gaines began as a technical engineer at Marshall. He developed control software for the Dynamic Solar Simulator, the RATT (Remote Automated Target Transporter), and a graphical user interface for an Advanced Video Guidance Sensor. He also designed control electronics for the RATT and Dynamic Solar Simulator.
"Early in my career, I worked in the Flight Robotics Lab," Gaines said. "I absolutely loved that job! So much so, I saw myself retiring doing that type of work. Later on, I decided to develop my career in other skillsets. I found leadership roles just as rewarding and challenging as well."
In 2008, Gaines became the deputy avionics and software lead for the Ares V heavy lift rocket. In 2011, he served as the avionics and software lead engineer for the SLS (Space Launch System) in support of the Spacecraft and Payload Integration Office. Gaines was the department lead engineer for the ECLSS (Environmental Control Life Support System) in 2012. He later became the senior integration lead for SLS secondary payloads safety in 2015.
Gaines served as the Quality Assurance (QA) branch chief in 2017. He was in communication with QA civil and contract engineers, ensuring all spaceflight hardware met quality requirements. In 2018, before becoming manager of the Safety and Quality Assurance department, he was the technical assistant there. He managed Marshall's workmanship standards and electrostatic programs while being a representative for NASA's Safety Culture Working Group.
Gaines lives in Harvest, Alabama, and has three adult children. His brother, Darryl Gaines, is the acting deputy for the Commercial Low Earth Orbit Development Program at NASA's Johnson Space Flight Center.
Joseph Gaines was selected as the 121st U.S. Army Reserve Soldier of the Year in 1992.
"I think having a good work ethic, developing more than one skill, along with being a good communicator and detail oriented is needed to be successful," he said. "Also learning from others as you branch out is very helpful."

Combatting Organizational Silence Focus of Mission Success Forum; Tag Taglilatelo Receives Golden Eagle Award
By Wayne Smith
Bob Conway, deputy director of the NASA Safety Center, discussed organizational silence and how it relates to safety and mission success during a Shared Experiences Forum at the agency's Marshall Space Flight Center on Feb. 22.
The theme of the forum was "The Impact of Breaking the Silence." Conway discussed factors that can contribute to organizational silence, like failing to call attention to problems that can potentially result in mission failures. The hybrid event was part of the Mission Success is in Our Hands safety initiative and held in Activities Building 4316.
Conway described organizational silence as a collective phenomenon of saying or doing little in response to perceived problems. He said organizations may verbalize openness but send conflicting signals to employees to keep quiet. Conway pointed to the space shuttle Challenger accident as an example of organizational silence.
"Are we allowing our folks to talk," Conway said. "Are we hearing what they have to say, and are we putting it all in context?"
Conway said an organization's culture has an impact on safety. He referenced the NASA Safety Reporting System as an internal method for anonymously reporting safety concerns.
"An organizational excellence DNA is learning lessons from the past, applying it forward, and most importantly, speaking up when we have that," Conway said. "The constant pursuit of excellence is what we always need to be doing. When you achieve excellence, safety and a lot of other things become effortless byproducts of it."
Mission Success is in Our Hands is a safety initiative collaboration between Marshall and Jacobs Engineering. The goal is to help team members make meaningful connections between their jobs and the safety and success of NASA missions.
As part of the forum, Mission Success is in Our Hands presented its 39th Golden Eagle Award to Tag Taglilatelo of Jacobs Space Exploration Group. The award recognizes individuals who have contributed to flight safety and mission assurance above and beyond their normal work requirements.
Bill Hill, director of Safety and Mission Assurance at Marshall, said Taglilatelo noticed an incorrect valve configuration that could have caused a hydrazine leak during an SLS (Space Launch System) booster test. As a result of his observation, the configuration was modified, leading to a safe test.
Management or peers can nominate any team member for the Golden Eagle Award. Honorees are typically recognized at quarterly Shared Experiences forums.

Listen to the Universe: New NASA Sonifications and Documentary
Three new sonifications of images from NASA's Chandra X-ray Observatory and other telescopes have been released in conjunction with a new documentary about the project that makes its debut on the NASA+ streaming platform.
Sonification is the process of translating data into sounds. In the case of Chandra and other telescopes, scientific data are collected from space as digital signals that are commonly turned into visual imagery. The sonification project takes these data through another step of mapping the information into sound.
The new sonifications feature different objects observed by NASA telescopes.
The first is MSH 11-52, a supernova remnant blowing a spectacular cloud of energized particles resembling the shape of a human hand, seen in data from Chandra, NASA's Imaging X-ray Polarimetry Explorer, or IXPE, and ground-based optical data.
M74 is a spiral galaxy like our Milky Way and this sonification combines data taken with NASA's James Webb and Hubble Space Telescopes as well as X-rays from Chandra.
The third object in this new sonification trio is nicknamed the Jellyfish Nebula, also known as IC 443. These data include X-rays from Chandra and the now-retired German ROSAT mission as well as radio data from NSF's Very Large Array and optical data from the Digitized Sky Survey.
The new documentary, "Listen to the Universe," now available on NASA+ explores how these sonifications are created and profiles the team that makes them possible.
Started in 2020, the NASA sonification project built off of other Chandra projects aimed at reaching blind and visually-impaired audiences. It has since shown to be meaningful to that community but also impacts much wider audiences, finding listeners through traditional and social media around the world.
"We are so excited to partner with NASA+, along with her collaborators at SYSTEMS Sounds, to help tell the story about NASA's sonification project," said Kimberly Arcand, Chandra's Visualization and Emerging Technology Scientist, who leads the sonification efforts. "It's wonderful to see how this project has grown and reached so many people."
NASA+ is the agency's new streaming platform, delivering video and other content about NASA to the public whenever and wherever they want to access it. The on-demand streaming service is available to download on most major platforms via the NASA App on iOS and Android mobile and tablet devices, as well as streaming media players Roku and Apple TV.
"Sonifications add a new dimension to stunning space imagery, and make those images accessible to the blind and low-vision community for the first time," said Liz Landau, who leads multimedia efforts for NASA's Astrophysics Division at NASA Headquarters and oversaw production of the "Listen to the Universe" documentary. "I was honored to help tell the story of how Dr. Arcand and the System Sounds team make these unique sonic experiences and the broad impact those sonifications have had."
