GoKawiilNASA crew completes year-long simulated Mars mission in Houston habitat
Four engineers exited a 158-square-metre 3D-printed habitat at NASA's Johnson Space Center on 31 October after more than a year inside, completing the second in a series of simulated Mars missions. During the mission, the crew grew their own food, ran science experiments, conducted simulated 'Marswalks' and endured communication delays of 13-22 minutes as well as a planned two-week blackout mimicking real Mars-Earth conditions.
GoKawiil's interpretation of the reporting above, not reported fact.
NASA says the data gathered on crew health, performance and isolation will shape protocols for future crewed Mars missions, which the agency has suggested could begin in the early 2030s, as well as inform lunar expeditions. Testing realistic communication delays and resource constraints on Earth lets researchers study psychological and logistical challenges without the risks of an actual deep-space mission.
