The X-38 is
NASA's Crew Return
Vehicle on the
International Space Station. It is completly autopiloted and according to
NASA's Web Site, it lands with the help of
parachute. But for the next years, they will to
atmospheric drop tests with it.
It is designed to carry up to six passengers. Rembering that the ISS is desigend for up to seven inhabitants, someone will have to use the Russian Soyuz vehicle to abadon the Station in case of an emergency.
( Perhaps this is the better choice, because the Soyuz has proved that it works.)
