In early November 2026, the second phase of #NASA’s three-part #CHAPEA (Crew Health and Performance Exploration Analog) mission series concluded. These missions serve as #simulations to test conditions for a potential future #crewedbase on #Mars. The tests take place within "Mars #DuneAlpha," a #habitat spanning approximately 160 square meters, located at NASA’s Lyndon B. Johnson #SpaceCenter in Houston, Texas. The participants' daily routine includes conducting #scientificexperiments, #cultivatingplants (using hydroponics), and performing #maintenancetasks. The program also features "outside" activities in an area that simulates the Martian landscape; for these, the participants must exit the base through an airlock while wearing pressurized #spacesuits. A crewed mission to Mars, including the establishment of a base there, entails a wide range of requirements. Beyond the months-long #journey, the low #gravity,to which humans would be permanently exposed, also presents obstacles to the success of such a mission. Yet, these factors were not part of the CHAPEA simulations conducted to date. Those simulations focused primarily on how a crew functions as a #team when living in long-term #isolation, left to their own devices on the surface of an alien planet. This also included #communicationdelays of up to 22 minutes, which roughly corresponds to the time it takes for a signal to travel between Mars and Earth. The results of the second Mars simulation experiment, which lasted 378 days, will be analyzed in the period following the mission. The third and final experiment in this series is already in preparation and is scheduled to begin no earlier than August 2027. © #StefanFWirth, November 2026 please support my science communication efforts https://t.co/4nN4eRHB6I references: NASA: https://t.co/Tj4GWeboot The Straits Times (2026): https://t.co/VvResC7Z6P #photo: The CHAPEA crews will live and work in a 1,700-square-foot, 3D-#printedhabitat located at NASA’s Johnson Space Center.
