The Space Exploration Vehicle (SEV) concept is designed to be flexible depending on the destination; the pressurized cabin can be used both for in-space missions and for surface exploration of planetary bodies, including near-Earth asteroids and Mars. The surface exploration version of the SEV has the cabin mounted on a chassis, with wheels that can pivot 360 degrees and drive about 10 kilometers per hour in any direction. It's about the size of a pickup truck (with 12 wheels) and can house two astronauts for up to 14 days with sleeping and sanitary facilities. Likewise, the in-space version of the SEV would have the same pressurized cabin on a flying platform; it too would allow two astronauts to stay on-site for 14 days.
