Inflatable spaceship set for test flight Nature

An inflatable lifeboat could one day ferry stranded astronauts back to Earth, if a prototype’s test flights are successful next month. The re-entry vehicle weighs just 130 kilograms and is being developed to carry cargo back from the International Space Station (ISS). But its inventors believe that it could also let astronauts bail out of the space station, or deliver robots to the surface of Mars.
