Scientists re-emerge after a year in Mars simulation project


The two women and two men spent the last 378 days in Houston's Mars Dune Alpha habitat, designed to mimic Red Planet conditions. They spent the year conducting "Marswalks" and operating under "additional stressors."

To loud applause, the four volunteers left NASA-built Mars Dune Alpha, where they had spent the past 378 days completely isolated from the outside world. Anca Selariu, Ross Brockwell, Nathan Jones and team leader Kelly Haston have spent the last year growing vegetables, conducting "Marswalks" and operating under what NASA calls "additional stressors." Julie Kramer, NASA's director of engineering, said the project "gives us an opportunity to learn all these critical things about these complex systems, and it's going to make going to Mars and back a lot safer."
