X-38: the International Space Station's Emergency Vehicle

The X38 was an emergency escape craft designed to carry up to seven astronauts from the International Space Station (ISS) back to Earth. It underwent various tests to ensure its aerodynamic efficiency and was to be delivered to the ISS by a space shuttle. The X38 featured a drone parachute and a large parafoil for safe descent, with a design that allowed for automatic operation. Despite its potential, the program was canceled in 2002 due to budget cuts, and the ISS now relies on Soyuz spacecraft for evacuations.
