Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut and Expedition 72 Commander Suni Williams displays a set of BioNutrients production packs during an experiment aboard the International Space Station. The experiment uses engineered yeast to produce nutrients and vitamins to support future astronaut health.NASA NASA’s BioNutrients series of experiments is testing ways to use microorganisms to make nutrients that will be needed for human health during future long-duration deep space exploration missions. Some vital nutrients lack the shelf-life needed to span multi-year human missions, such as a mission to Mars, and may need to be produced in space to support astronaut health. To meet this need, the BioNutrients project uses a biomanufacturing approach similar to making familiar fermented foods, such as yogurt. But these foods also will include specific types and amounts of nutrients that crew will be able to consume in the future.
The first experiment in the series, BioNutrients-1, set out to assess the five-year stability and performance of a hand-held system – called a production pack – that uses an engineered microorganism, yeast, to manufacture fresh vitamins on-demand and in space. The BioNutrients-1 experiments began after multiple sets of production packs launched to the station in 2019. This collection included spare production packs as backups to be used in case an experiment needs to be re-run during the five-year study. The planned experiments concluded in January 2024 spare production packs still remaining aboard the orbiting lab and in the BioNutrients lab at NASA’s Ames Research Center in California’s Silicon Valley, where the ground team runs experiments in parallel to the crew operations.
Leaders at NASA’s International Space Station and Game Changing Development programs worked to coordinate the crew time needed to perform an additional BioNutrients-2 experiment using the spare packs. This extended the study’s timeline to almost six years in orbit, allowing valuable crew observations and data from the additional experiment run to be applied to a follow-on experiment, BioNutrients-3, which completed its analog astronaut experiment in April 2024, and is planned to launch to the station this year. Astronauts on the space station will freeze the sample and eventually it will be returned to Earth for analysis to see how much yeast grew and how much nutrient the experiment produced. This will help us understand how the shelf stability of the packets.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut Douglas Hurley is helped out of the SpaceX Crew Dragon Endeavour spacecraft onboard the SpaceX GO Navigator recovery ship after he and NASA astronaut Robert Behnken landed in the Gulf of Mexico off the coast of Pensacola, Florida, Sunday, Aug. 2, 2020. The Demo-2 test flight for NASA’s Commercial Crew Program was the first to deliver astronauts to the International Space Station and return them safely to Earth onboard a commercially built and operated spacecraft. Behnken and Hurley returned after spending 64 days in space. Photo Credit: (NASA/Bill Ingalls)NASA New spacecraft that will transport crews to the Lunar and Martian surfaces and return them to Earth may have diverse landing modalities which will function in different landing environments. Additionally, the crew may be deconditioned on landing, impacting their ability to independently egress the vehicles, perform post-landing tasks in a timely manner, and perform surface EVAs post-landing -including those required for emergencies.

Boeing’s Orbital Flight Test-2 (OFT-2) is Starliner’s second uncrewed flight test to the International Space Station as part of NASA’s Commercial Crew Program. OFT-2 serves as an end-to-end test of the system’s capabilities. Photo Credit: (NASA/Bill Ingalls) Directed Acyclic Graph Files

NASA astronaut and Expedition 65 Flight Engineer Mark Vande Hei sets up the International Space Station’s exercise bicycle, also known as the Cycle Ergometer with Vibration Isolation and Stabilization (CEVIS), inside the U.S. Destiny laboratory module. Vande Hei later strapped himself on the CEVIS and attached sensors to himself for a workout study measuring aerobic capacity in space.NASA Exposure to the microgravity environment causes muscle size, strength, and endurance to decline. Based on ISS data, if crew adhere to the exercise schedule and have access to adequate exercise countermeasure systems then on average, they return with minimal losses of muscle size, strength, and endurance. New exploration countermeasures systems will be different from ISS and may not have the capability to support exercise as required to maintain human performance.

Thornton (out of frame) with a medical test that requires use of the treadmill exercising device designed for spaceflight by the STS-8 medical doctor on Sept. 5, 1983. Forward lockers with data recording units and checklist notebooks are to the left of Bluford. Guy Bluford was the first African-American astronaut to fly into space. Directed Acyclic Graph Files

NASA astronaut Anne McClain is inside the Destiny laboratory module surrounded by exercise gear, including laptop computers and sensors that measure physical exertion and aerobic capacity, during a workout session aboard the International Space Station. NASA Spaceflight causes measures of maximum aerobic capacity to decline, which can result in impaired mission task performance. Based on ISS data, if crew adhere to existing exercise schedules and have access to adequate exercise countermeasure systems, then on average, they return with minimal losses of aerobic fitness. New exploration countermeasures systems will be different from ISS and may not have the capability to support exercise as required to maintain human performance.
