A NASA crew has successfully completed a year-long simulated mission to Mars, spending 378 days in a 3D-printed habitat in Houston. The four-member team lived and worked as if they were on the red planet, conducting experiments and adapting to the challenges of long-duration space travel without ever leaving Earth. This mission is part of NASA's ongoing efforts to prepare for future manned missions to Mars, with the next crew set to embark on a similar year-long mission in 2025. The simulation aims to gather valuable data on the psychological and physical effects of extended space missions, crucial for planning future explorations beyond our planet.
