      NASA’s Human Landing System (HLS) will transport the next astronauts that land on the Moon, including the first woman and first person of color, beginning with Artemis III. For safety and mission success, the landers and other equipment in development for NASA’s Artemis campaign must work reliably in the harshest of environments.
      The Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, provides engineers with thermal analysis of materials that may be a prototype or in an early developmental stage using a vacuum chamber, back left, and a conduction chamber, right. NASA/Ken Hall Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are currently testing how well prototype insulation for SpaceX’s Starship HLS will insulate interior environments, including propellant storage tanks and the crew cabin. Starship HLS will land astronauts on the lunar surface during Artemis III and Artemis IV.
      Marshall’s Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) laboratory provides the resources and tools for an early, quick-check evaluation of insulation materials destined for Artemis deep space missions.
      “Marshall’s HI-TTeMP lab gives us a key testing capability to help determine how well the current materials being designed for vehicles like SpaceX’s orbital propellant storage depot and Starship HLS, will insulate the liquid oxygen and methane propellants,” said HLS chief engineer Rene Ortega. “By using this lab and the expertise provided by the thermal engineers at Marshall, we are gaining valuable feedback earlier in the design and development process that will provide additional information before qualifying hardware for deep space missions.”
      A peek inside the conductive test chamber at NASA Marshall’s HI-TTeMP lab where thermal engineers design, set up, execute, and analyze materials destined for deep space to better understand how they will perform in the cold near-vacuum of space. NASA/Ken Hall On the Moon, spaceflight hardware like Starship HLS will face extreme temperatures. On the Moon’s south pole during lunar night, temperatures can plummet to -370 degrees Fahrenheit (-223 degrees Celsius). Elsewhere in deep space temperatures can range from roughly 250 degrees Fahrenheit (120 degrees Celsius) in direct sunlight to just above absolute zero in the shadows.
      There are two primary means of managing thermal conditions: active and passive. Passive thermal controls include materials such as insulation, white paint, thermal blankets, and reflective metals. Engineers can also design operational controls, such as pointing thermally sensitive areas of a spacecraft away from direct sunlight, to help manage extreme thermal conditions. Active thermal control measures that could be used include radiators or cryogenic coolers.
      Engineers use two vacuum test chambers in the lab to simulate the heat transfer effects of the deep space environment and to evaluate the thermal properties of the materials. One chamber is used to understand radiant heat, which directly warms an object in its path, such as when heat from the Sun shines on it. The other test chamber evaluates conduction by isolating and measuring its heat transfer paths.
      NASA engineers working in the HI-TTeMP lab not only design, set up, and run tests, they also provide insight and expertise in thermal engineering to assist NASA’s industry partners, such as SpaceX and other organizations, in validating concepts and models, or suggesting changes to designs. The lab is able to rapidly test and evaluate design updates or iterations.
      NASA’s HLS Program, managed by NASA Marshall, is charged with safely landing astronauts on the Moon as part of Artemis. NASA has awarded contracts to SpaceX for landing services for Artemis III and IV and to Blue Origin for Artemis V. Both landing services providers plan to transfer super-cold propellant in space to send landers to the Moon with full tanks.
      With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of Mars. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the HLS, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

      Johnson Space Center Vibration Test FacilityNASA Nov. 14, 2024
      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.
