Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA Energy Program Manager for Facility Projects Wayne Thalasinos, left, stands with NASA Stennis Sustainability Team Lead Alvin Askew at the U.S. Department of Energy in Washington, D.C., on Oct. 30. The previous day, the Department of Energy announced NASA Stennis will receive a $1.95 million grant for an energy conservation project at the south Mississippi center. The Stennis Sustainability Team consists of NASA personnel and contract support. NASA members include Askew, Missy Ferguson and Teenia Perry. Contract members include Jordan McQueen (Synergy-Achieving Consolidated Operations and Maintenance); Michelle Bain (SACOM); Matt Medick (SACOM); Thomas Mitchell (SACOM); Lincoln Gros (SACOM), and Erik Tucker (Leidos). NASA Stennis NASA’s Stennis Space Center has been awarded a highly competitive U.S. Department of Energy grant to transform its main administration building into a facility that produces as much renewable energy as it uses.
Following an Oct. 29 announcement, NASA Stennis, located near Bay St. Louis, Mississippi, will receive $1.95 million through the Assisting Federal Facilities with Energy Conservation Technologies (AFFECT) Program. The grant will fund installation of a four-acre solar panel array onsite that can generate up to 1 megawatt of electricity.
“This is a flagship project for our NASA center,” said NASA Stennis Director John Bailey. “It will provide renewable energy to help reduce our carbon footprint, contributing to NASA’s agencywide goal of zero greenhouse gas emissions by 2030.”
The AFFECT Program awards grants to help the federal government achieve its goal of net-zero greenhouse gas emissions by all federal buildings by 2045. More than $1 billion in funding proposals was requested by federal agencies for the second, and final, phase of the initiative. A total of $149.87 million subsequently was awarded for 67 energy conservation and clean energy projects at federal facilities across 28 U.S. states and territories and in six international locations. NASA Stennis is the only agency in Mississippi to receive funding.
The site’s solar panel array will build on an $1.65 million energy conservation project already underway at the south Mississippi site to improve energy efficiency. The solar-generated electricity can be used in a number of ways, from powering facility lighting to running computers. The array also will connect to the electrical grid to allow any excess energy to be utilized elsewhere onsite.
“This solar panel addition will further enhance our energy efficiency,” said NASA Stennis Sustainability Team Lead Alvin Askew. “By locating the solar photovoltaic array by the Emergency Operations Center, it also has potential future benefits in providing backup power to that facility during outages.”
The NASA Stennis proposal was one of several submitted by NASA centers for agency consideration. Following an agency review process, NASA submitted multiple projects to the Department of Energy for grant consideration.
“This was a very competitive process, and I am proud of the NASA Stennis Sustainability Team,” NASA Stennis Center Operations Director Michael Tubbs said. “The team’s hard work in recent years and its commitment to continuous improvement in onsite energy conversation laid the groundwork to qualify for this grant. Mr. Askew, in particular, continues to be a leader in creative thinking, helping us meet agency sustainability goals.”
The NASA Stennis administration building was constructed in 2008 as a Leadership in Energy and Environmental Design-certified, all-electric facility and currently has net-zero emissions.

Dr. Annie Meier (second from left) and her team inside the Applied Chemistry Lab at NASA’s Kennedy Space Center in Florida began supplementing their normal workload in mid-2023 with efforts to improve the lab’s sustainable practices. In 2024, the laboratory became the first at NASA to receive certification from the non-profit My Green Lab for its efforts in sustainability.NASA/Kim Shiflett NASA’s Kennedy Space Center in Florida has a long record of achievements in sustainability and recently added another to the list when the spaceport’s Applied Chemistry Lab became the first in the agency to be certified for its environmentally conscious practices.
The My Green Lab Certification recognizes sustainability best practices in research facilities around the world. The certification program run by My Green Lab, a non-profit dedicated to creating a culture of sustainability through science, is considered a key measure of progress towards a zero-carbon future by the United Nations Race to Zero campaign.
“When I heard our lab achieved certification, I was so happy,” said Dr. Annie Meier, one of the laboratory’s chemical engineers. “It meant we could now make a conscious effort to share these green practices with all who work in our lab. We even added them to our training materials for new and incoming members in the lab.”
The lab performs research and technology development for a wide range of chemistry and engineering-related applications to solve the unique operational needs of NASA and outside partners. The lab primarily focuses on in-situ resource utilization and addressing technology gaps related to lunar and Martian sustainability. The lab’s scientists also provide expertise in the fields of logistics reduction, plasma science, hypergolic fuels, analytical instrumentation, and gas analysis.
While sustainability has long been a focus of the lab, the journey to the certification began when Riley Yager, a doctoral student from University of Alabama at Birmingham – where Meier was a technical monitor – shared her knowledge of the program after pursuing green lab practices at her university.
“I work as a sustainability ambassador at my university, so I knew of this program,” Yager said. “Sustainable practices are something woven into my everyday life, so naturally I wanted to bring those practices into my lab environments.”
After learning about the program from Yager and discovering the many other academic institutions and companies certified globally, Meier submitted a proposal to NASA and obtained funding to pursue certification for the Applied Chemistry Lab.
After a kickoff event hosted by My Green Lab in April 2023, the lab’s path to certification began with a self-assessment survey, in which members of the lab answered a series of questions about their practices in areas such as cold storage, green chemistry, infrastructure energy, resource management, waste reduction, and water. My Green Lab collected and analyzed the answers, providing a baseline assessment and recommendations to improve the lab’s sustainable practices.
“We took their initial survey and learned we had lots of room for improvements as a lab,” Meier said. “Then I worked with a few interns over the summer to spearhead the ‘green team’ to implement changes and get momentum from the entire lab.”
The lab began with minimizing purchases by improving efficiencies during the inventory process. The team also performed a waste audit of all seven of its laboratories. They adopted nitrile glove and pipette tip box recycling, reviewed the “12 principles of green chemistry” with the lab members, and installed stickers and signage about what can and cannot be unplugged to save energy. Additionally, they installed low-flow aerators on the lab tap sinks to reduce flow, and the lab now uses a recycling sink to save on water or solvents for cleaning parts.
As luck would have it, Yager ended up working at the Applied Chemistry Lab on a NASA fellowship and became a member of the green team.
“It was really fun to see that come full circle,” Meier said. “Almost all members of the lab, from our fellows to most senior members, used their self-motivation to get on the sustainability train.”
The green team continued to grow as the lab implemented changes to become more sustainable. Just over six months after the kickoff event, they completed another assessment survey. With possible certification levels of bronze, silver, gold, platinum, and green – the level that adheres closest to My Green Lab’s highest standards – the ACL was certified green, marking the first time any NASA center obtained a My Green Lab Certification.
“Our lab is looking to sustain these green practices and achieve the same status when we are reassessed in the future,” Meier said. “This effort could be a wonderful catalyst to inspire other work groups to lean towards more ‘green’ practices at the frontline in our laboratories.”
The NASA Kennedy lab joined over 2,500 labs in a range of sectors that received the My Green Lab certification. Maintaining the distinction will require recertification every two years.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 quiet supersonic research aircraft sits in its run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California, firing up its engine for the first time. These engine-run tests start at low power and allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter.NASA/Carla Thomas NASA’s Quesst mission marked a major milestone with the start of tests on the engine that will power the quiet supersonic X-59 experimental aircraft.
These engine-run tests, which began Oct. 30, allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. In previous tests, the X-59 used external sources for power. The engine-run tests set the stage for the next phase of the experimental aircraft’s progress toward flight.
The X-59 team is conducting the engine-run tests in phases. In this first phase, the engine rotated at a relatively low speed without ignition to check for leaks and ensure all systems are communicating properly. The team then fueled the aircraft and began testing the engine at low power, with the goal of verifying that it and other aircraft systems operate without anomalies or leaks while on engine power.
Lockheed Martin test pilot Dan Canin sits in the cockpit of NASA’s X-59 quiet supersonic research aircraft in a run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California prior to its first engine run. These engine-run tests featured the X-59 powered by its own engine, whereas in previous tests, the aircraft depended on external sources for power. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter.NASA/Carla Thomas “The first phase of the engine tests was really a warmup to make sure that everything looked good prior to running the engine,” said Jay Brandon, NASA’s X-59 chief engineer. “Then we moved to the actual first engine start. That took the engine out of the preservation mode that it had been in since installation on the aircraft. It was the first check to see that it was operating properly and that all the systems it impacted – hydraulics, electrical system, environmental control systems, etc. – seemed to be working.”
The X-59 will generate a quieter thump rather than a loud boom while flying faster than the speed of sound. The aircraft is the centerpiece of NASA’s Quesst mission, which will gather data on how people perceive these thumps, providing regulators with information that could help lift current bans on commercial supersonic flight over land.
The engine, a modified F414-GE-100, packs 22,000 pounds of thrust, which will enable the X-59 to achieve the desired cruising speed of Mach 1.4 (925 miles per hour) at an altitude of approximately 55,000 feet. It sits in a nontraditional spot – atop the aircraft — to aid in making the X-59 quieter.
Engine runs are part of a series of integrated ground tests needed to ensure safe flight and successful achievement of mission goals. Because of the challenges involved with reaching this critical phase of testing, the X-59’s first flight is now expected in early 2025. The team will continue progressing through critical ground tests and address any technical issues discovered with this one-of-a-kind, experimental aircraft. The X-59 team will have a more specific first flight date as these tests are successfully completed.
The testing is taking place at Lockheed Martin’s Skunk Works facility in Palmdale, California. During later phases, the team will test the aircraft at high power with rapid throttle changes, followed by simulating the conditions of an actual flight.

It’s like the first note of a symphony, where years of teamwork behind the scenes are now being put to the test to prove our efforts have been effective, and the notes will continue to play a harmonious song to flight.”
After the engine runs, the X-59 team will move to aluminum bird testing, where data will be fed to the aircraft under both normal and failure conditions. The team will then proceed with a series of taxi tests, where the aircraft will be put in motion on the ground. These tests will be followed by final preparations for first flight.

President John F. Kennedy’s national commitment to land a man on the Moon and return him safely to the Earth before the end of the decade posed multiple challenges, among them how to train astronauts to land on the Moon, a place with no atmosphere and one-sixth the gravity on Earth. The Lunar Landing Research Vehicle (LLRV) and its successor the Lunar Landing Training Vehicle (LLTV) provided the training tool to simulate the final 200 feet of the descent to the lunar surface. The ungainly aircraft made its first flight on Oct. 30, 1964, at NASA’s Flight Research Center (FRC), now NASA’s Armstrong Flight Research Center (AFRC) in California. The Apollo astronauts who completed landings on the Moon attributed their successes largely to training in these vehicles.
The first Lunar Landing Research Vehicle silhouetted against the rising sun on the dry lakebed at Edwards Air Force Base in California’s Mojave Desert.
In December 1961, NASA Headquarters in Washington, D.C., received an unsolicited proposal from Bell Aerosystems in Buffalo, New York, for a design of a flying simulator to train astronauts on landing a spacecraft on the Moon. Bell’s approach, using their design merged with concepts developed at NASA’s FRC, won approval and the space agency funded the design and construction of two Lunar Landing Research Vehicles (LLRV). At the time of the proposal, NASA had not yet chosen the method for getting to and landing on the Moon, but once NASA decided on Lunar Orbit Rendezvous in July 1962, the Lunar Module’s (LM) flying characteristics matched Bell’s proposed design closely enough that the LLRV served as an excellent trainer.
Two views of the first Lunar Landing Research Vehicle shortly after its arrival and prior to assembly at the Flight Research Center, now NASA’s Armstrong Flight Research Center, in California.
Bell Aerosystems delivered the LLRV-1 to FRC on April 8, 1964, where it made history as the first pure fly-by-wire aircraft to fly in Earth’s atmosphere. Its design relied exclusively on an interface with three analog computers to convert the pilot’s movements to signals transmitted by wire and to execute his commands. The open-framed LLRV used a downward pointing turbofan engine to counteract five-sixths of the vehicle’s weight to simulate lunar gravity, two rockets provided thrust for the descent and horizontal translation, and 16 LM-like thrusters provided three-axis attitude control. The astronauts could thus simulate maneuvering and landing on the lunar surface while still on Earth. The LLRV pilot could use an aircraft-style ejection seat to escape from the vehicle in case of loss of control.

Right: NASA chief test pilot Joseph “Joe” A. Walker, left, demonstrates the features of LLRV-1 to President Lyndon B. Johnson during his visit to FRC.
Engineers conducted numerous tests to prepare the LLRV for its first flight. During one of the engine tests, the thrust generated was higher than anticipated, lifting crew chief Raymond White and the LLRV about a foot off the ground before White could shut off the engines. On June 19, during an official visit to FRC, President Lyndon B. Johnson inspected the LLRV featured on a static display. The Secret Service would not allow the President to sit in the LLRV’s cockpit out of an overabundance of caution since the pyrotechnics were installed, but not yet armed, in the ejection seat. Following a Preflight Readiness Review held Aug. 13 and 14, managers cleared the LLRV for its first flight.

In the early morning of Oct. 30, 1964, FRC chief pilot Joseph “Joe” A. Walker arrived at Edwards Air Force Base’s (AFB) South Base to attempt the first flight of the LLRV. Walker, a winner of both the Collier Trophy and the Harmon International Trophy, had flown nearly all experimental aircraft at Edwards including 25 flights in the X-15 rocket plane. On two of his X-15 flights, Walker earned astronaut wings by flying higher than 62 miles, the unofficial boundary between the Earth’s atmosphere and space. After strapping into the LLRV’s ejection seat, Walker ran through the preflight checklist before advancing the throttle to begin the first flight. The vehicle rose 10 feet in the air, Walker performed a few small maneuvers and then made a soft landing after having flown for 56 seconds. He lifted off again, performed some more maneuvers, and landed again after another 56 seconds. On his third flight, the vehicle’s electronics shifted into backup mode and he landed the craft after only 29 seconds. Walker seemed satisfied with how the LLRV handled on its first flights.

Walker took LLRV-1 aloft again on Nov. 16 and eventually completed 35 test flights with the vehicle. Test pilots Donald “Don” L. Mallick, who completed the first simulated lunar landing profile flight during the LLRV’s 35th flight on Sept. 8, 1965, and Emil E. “Jack” Kluever, who made his first flight on Dec. 13, 1965, joined Walker to test the unique aircraft. Joseph S. “Joe” Algranti and Harold E. “Bud” Ream, pilots at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center (JSC) in Houston, travelled to FRC to begin training flights with the LLRV in August 1966. Workers at FRC assembled the second vehicle, LLRV-2, during the latter half of 1966. In December 1966, after 198 flights workers transferred LLRV-1 to Ellington AFB near MSC for the convenience of astronaut training, and LLRV-2 followed in January 1967 after completing six test flights at FRC. The second LLRV made no further flights, partly because the three Lunar Landing Training Vehicles (LLTVs), more advanced models that better simulated the LM’s flying characteristics, began to arrive at Ellington in October 1967. Neil A. Armstrong completed the first astronaut flights aboard LLRV-1 on Mar. 23, 1967, and flew 21 flights before ejecting from the vehicle on May 6, 1968, seconds before it crashed. He later completed his lunar landing certification flights using LLTV-2 in June 1969, one month before peforming the actual feat on the Moon.

Middle: Apollo 12 Commander Charles “Pete” Conrad prepares to fly LLTV-2 in July 1969. Right: Apollo 14 Commander Alan B. Shepard flies LLTV-3 in December 1970.
All Apollo Moon landing mission commanders and their backups completed their lunar landing certifications using the LLTV, and all the commanders attributed their successful landings to having trained in the LLTV. Apollo 8 astronaut William A. Anders, who along with Armstrong completed some of the early LLRV test flights, called the training vehicle “a much unsung hero of the Apollo program.” During the flight readiness review in January 1970 to clear LLTV-3 for astronaut flights, Apollo 11 Commander Armstrong and Apollo 12 Commander Charles “Pete” Conrad, who had by then each completed manual landings on the Moon, spoke positively of the LLTV’s role in their training. Armstrong’s overall impression of the LLTV: “All the pilots … thought it was an extremely important part of their preparation for the lunar landing attempt,” adding “It was a contrary machine, and a risky machine, but a very useful one.” Conrad emphasized that were he “to go back to the Moon again on another flight, I personally would want to fly the LLTV again as close to flight time as possible.” During the Apollo 12 technical debriefs, Conrad stated the “the LLTV is an excellent training vehicle for the final phases. I think it’s almost essential. I feel it really gave me the confidence that I needed.” During the postflight debriefs, Apollo 14 Commander Alan B. Shepard stated that he “did feel that the LLTV contributed to my overall ability to fly the LM during the landing.”

David R. Scott, Apollo 15 commander, stated in the final mission report that “the combination of visual simulations and LLTV flying provided excellent training for the actual lunar landing. Comfort and confidence existed throughout this phase.” In the Apollo 15 postflight debrief, Scott stated that he “felt very comfortable flying the vehicle (LM) manually, because of the training in the LLTV, and there was no question in my mind that I could put it down where I wanted to. I guess I can’t say enough about that training. I think the LLTV is an excellent simulation of the vehicle.” Apollo 16 Commander John W. Young offered perhaps the greatest praise for the vehicle just moments after landing on the lunar surface: “Just like flying the LLTV. Piece of cake.” Young reiterated during the postflight debriefs that “from 200 feet on down, I never looked in the cockpit. It was just like flying the LLTV.” Apollo 17 Commander Eugene A. Cernan stated in the postflight debrief that “the most significant part of the final phases from 500 feet down, … was that it was extremely comfortable flying the bird. I contribute (sic) that primarily to the LLTV flying operations.”
