NASA selects four crewmembers for second 378‑day Mars surface simulation

NASA has selected four crewmembers for its second 378‑day simulation of living and working on the surface of Mars. The year‑long, Earth‑based analog will recreate Mars surface conditions to assess long‑duration habitation, mission operations and crew performance ahead of future crewed missions.

What Hype is tracking

The mission is a 378‑day analog that generates long‑duration human factors and systems data critical to planning crewed Mars missions; see earlier coverage of NASA's year‑long 3D‑printed Mars habitat simulation (https://hype.aero/?story=abf2cc07-455d-42da-a54f-d5f3b371345b).
Crew composition and selection criteria influence required skills, training and contractor support; this follows reporting on NASA naming military test pilots and operational aviators to comparable year‑long simulations (https://hype.aero/?story=d8ad07d0-c578-492b-8f96-61b872a0bece).
The program ties into NASA's broader human exploration roadmap and capability needs for Mars surface operations and ascent architectures (https://hype.aero/?story=75408af5-231d-43d9-a4d1-11354ae19515).
