A single-person spacecraft is a vehicle designed for space travel.[1] The concept has been used in science fiction and actual ships[1] such as the Mercury capsule, Vostok and some suborbital designs. Single-person spacecraft have been envisioned as a supplement or replacement for space suits in certain applications. The Von Braun Bottle suit of the 1950s functions as a hybrid of a space suit and a one-person spacecraft.[2][3]
