NASA Johnson Invites Proposals to Lease Vibration Test Facility
NASA’s Johnson Space Center is seeking proposals for the use of its historic, but underused, Vibration and Acoustic Test Facility. Prospective tenants must submit facility walk-through requests by Monday, Nov. 18.
Final proposals are due by 12 p.m. EST Monday, Dec. 16, and must promote activities that will build, expand, modernize, or operate aerospace-related capabilities at NASA Johnson and help preserve the historic and iconic building through preservation and adaptive reuse.
NASA plans to sign a National Historic Preservation Act (NHPA) lease agreement for the facility, also known as Building 49, for a five-year base period and one five-year extension to be negotiated between NASA and the tenant. To request a walk-through, send an email to hq-realestate@mail.nasa.gov.
“This historic facility has been used for decades to ensure the success and safety of all human spaceflight missions by putting engineering designs and hardware to the ultimate stress tests,” said NASA Johnson Director Vanessa Wyche. “For more than 60 years, NASA Johnson has been the hub of human space exploration and this agreement will be a vital part of the center’s efforts to develop a robust and durable space economy that refines our understanding of the solar system and space exploration.”
All proposals must adhere to the guidelines detailed in the Agency Announcement for Proposals describing concept plans for development of the property, including any modifications proposed to the building; a statement of financial capability to successfully achieve and sustain operations, demonstrated experience with aerospace-related services or other space-related activities, and a detailed approach to propelling the space economy.
The nine-story building complex has a gross square footage of 62,737 square feet and consists of a north wing measuring 62 feet long, 268 feet wide and 106 feet tall, and a central wing about 64 feet long and 115 feet wide. Building 49 currently houses five laboratories, including the General Vibration Laboratory, Modal Operations Laboratory, Sonic Fatigue Laboratory, Spacecraft Acoustic Laboratory, and Spacecraft Vibration Laboratory. The south administrative portion of the building is not included in the property offered for lease.
As the home of Mission Control Center for the agency’s human space missions, astronaut training, robotics, human health and space medicine, NASA Johnson leads the way for the human exploration. Leveraging its unique role and location, the center is developing multiple lease agreements, including the recently announced Exploration Park, to sustain its key role in helping the human spaceflight community foster a robust space.
In the coming years, NASA and its academic, commercial, and international partners will see the completion of the International Space Station Program, the commercial development of low Earth orbit, and the first human Artemis campaign missions establishing sustainable human presence on the Moon in preparation for human missions to Mars.
Johnson already is leading the commercialization of space with the commercial cargo and crew programs and private astronaut missions to the space station. The center also is supporting the development of commercial space stations in low Earth orbit, and lunar-capable commercial spacesuits and lunar landers that will be provided as services to both NASA and the private sector to accelerate human access to space. Through the development of Exploration Park, the center will broaden the scope of the human spaceflight community that is tackling the many difficult challenges ahead.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Note: The following article is part of a series highlighting propulsion testing at NASA’s Stennis Space Center. To access the entire series, please visit: https://www.nasa.gov/feature/propulsion-powering-space-dreams/.
Contrary to the popular saying, work conducted by the propulsion test team at NASA’s Stennis Space Center is rocket science – and requires all the talent, knowledge, and expertise the term implies.
Rocket science at NASA Stennis, located near Bay St. Louis, Mississippi, has helped safely power American space dreams for almost 60 years ago. The accumulated knowledge and skills of the site’s test team continue to benefit NASA and commercial aerospace companies, thanks to new generations of skilled engineers and operators.
“The innovative, can-do attitude started with the founding of the south Mississippi site more than six decades ago,” said NASA Stennis Director John Bailey. “The knowledge, skills, and insight of a versatile team continue supporting NASA’s mission and goals of commercial aerospace companies by routinely conducting successful propulsion testing at NASA Stennis.”
Test team personnel perform facility data review following completion of a liquid oxygen cold-flow activation activity on the E-1 Test Stand at NASA’s Stennis Space Center on March 23, 2016. Activation of the test cell was in preparation for testing L3Harris’ (then known as Aerojet Rocketdyne) AR1 rocket engine pre-burner and main injector. The versatile four-stand E Test Complex includes 12 active test cell positions capable of various component, engine, and stage test activities for NASA and commercial projects. NASA/Stennis Operators at NASA’s High Pressure Gas Facility conduct a critical stress test Oct. 18-19, 2018, to demonstrate the facility’s readiness to support testing of the core stage of NASA’s powerful SLS (Space Launch System) rocket. The High Pressure Gas Facility was critical in producing and delivering gases needed for SLS core stage testing ahead of the successful launch of Artemis I. NASA/Stennis Test control center crews at NASA’s Stennis Space Center’s simulate full operations of core stage testing Dec. 13, 2019, for NASA’s powerful SLS (Space Launch System) rocket on the Thad Cochran Test Stand (B-2). NASA Stennis conducted SLS core stage testing in 2020-21 ahead of the successful Artemis I mission. NASA/Stennis A sitewide stress test at NASA’s Stennis Space Center on Dec. 13, 2019, simulates full operations needed during SLS (Space Launch System) core stage testing. The 24-hour exercise involved crews across NASA Stennis, including at the High Pressure Water Facility that provided needed generator power and water flow to the Thad Cochran Test Stand (B-2) during testing.NASA/Stennis The NASA Stennis team exhibits a depth and breadth of experience and expertise likely unsurpassed anywhere in the world.
The depth is built on decades of propulsion test experience. Veteran team members of today learned from those working during the Apollo era, who overcame various engineering, technical, communications, and mechanical difficulties in testing the Saturn V rocket stages that powered humans to the Moon. During 43 stage firings, the team accumulated an estimated 2,475 years of rocket engine test expertise.
Members of the Apollo test team then joined with new engineers and operators to test main engines that powered 30 years of space shuttle missions. From 1975 to 2009, the team supported main engine development, certification, acceptance, and anomaly testing with over 2,300 hot fires and more than 820,000 seconds of accumulated hot-fire time.
“NASA Stennis is unique because of the proven test operations expertise passed from generation to generation,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate. “It is expertise you can trust to deliver what is needed.”
A member of the Fred Haise Test Stand (formerly the A-1 Test Stand) operations team examines the progress of a cold-shock test on May 1, 2014. The test marked a milestone in preparing the stand to test RS-25 rocket engines that will help power NASA’s SLS (Space Launch System) rocket.NASA/Stennis In addition to depth, the site team also has a breadth of experience that gives it unparalleled versatility and adaptability.
Part of that comes from the nature of the center itself. NASA Stennis is the second largest NASA center in terms of geography, but the civil servant workforce is small. As a result, test team members work on a range of propulsion projects, from testing components on smaller E Test Complex cells to firing large engines and even rocket stages on the heritage Apollo-era stands.
“Our management have put us in a position to be successful,” said NASA engineer Josh Greiner. “They have helped move us onto the test stands and given us a huge share of the responsibility of leading projects early in our career, which provides us the confidence and opportunity to conduct tests.”
In addition, center leaders made a deliberate decision more than a decade ago to return test stand operations to the NASA team. Prior to that time, stand operations were in the hands of contractors under NASA supervision. The shift allowed the civil servant test team to fine-tune its skill set even as it continued to work closely with contractor partners to support both government and commercial aerospace propulsion projects.
An image from October 2022 shows NASA engineers preparing for the next RS-25 engine test series at NASA’s Stennis Space Center by monitoring the reload of propellant tanks to the Fred Haise Test Stand (formerly the A-1 Test Stand). RS-25 engines are powered by a mix of liquid hydrogen and liquid oxygen.NASA/Stennis An image from October 2022 shows test team personnel ensuring pressures and flow paths are set properly for liquid oxygen to be transferred to the Fred Haise Test Stand (formerly the A-1 Test Stand), pictured in the background.NASA/Stennis An image from August 2023 shows test team personnel inspecting a pump during an initial chill down activity at the E-3 Test Complex. The versatile four-stand E Test Complex includes 12 active test cell positions capable of various component, engine, and stage test activities for NASA and commercial programs and projects. NASA/Stennis An image from September 2023 shows test team personnel preparing for future SLS (Space Launch System) exploration upper stage testing that will take place on the B-2 side of the Thad Cochran Test Stand. NASA’s new upper stage is being built as a more powerful SLS second stage to send the Orion spacecraft and heavier payloads to deep space. It will fly on the Artemis missions following a series of Green Run tests of its integrated systems at NASA Stennis. The test series will culminate with a hot fire of the four RL10 engines that will power the upper stage.NASA/Stennis An image from September 2023 shows test team personnel preparing for future SLS (Space Launch System) exploration upper stage testing by conducting a liquid hydrogen flow procedure.

The upper stage will undergo a series of Green Run tests of its integrated systems on the B-2 side of the Thad Cochran Test Stand at NASA Stennis.NASA/Stennis The evolution and performance of the NASA Stennis team was illustrated in stark fashion in June/July 2018 when a blended team of NASA, Defense Advanced Research Projects Agency, Aerojet Rocketdyne, Boeing, and Syncom Space Services engineers and operators test fired an AR-22 rocket engine 10 times in a 240-hour period.
The campaign marked the first time a large liquid oxygen/liquid hydrogen engine had been tested so often in such a short period of time. The test team overcame a variety of challenges, including a pair of lightning strikes that threatened to derail the entire effort. Following completion of the historic series, a NASA engineer who helped lead the campaign recounted one industry observer who repeatedly characterized the site’s test team as nothing less than a national asset.
The experienced site workforce now tests RS-25 engines and propulsion systems for NASA’s Artemis campaign, including those that will help power Artemis missions to the Moon for scientific discovery and economic benefits. The NASA Stennis team also supports a range of commercial aerospace propulsion test activities, facilitating continued growth in capabilities. For instance, the team now has experience working with oxygen, hydrogen, methane, and kerosene propellants.
“The NASA and contractor workforce at NASA Stennis is second to none when it comes to propulsion testing,” Schuyler said. “Many of the current employees have been involved in rocket engine testing for over 30 years, and newer workers are being trained under these seasoned professionals.”

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.
