Dream Chaser is an American reusable lifting-body spaceplane developed by Sierra Space. Originally intended as a crewed vehicle, the Dream Chaser Space System is set to be produced after the Dream Chaser Cargo System cargo variant is operational. The crewed variant is planned to carry up to seven people and cargo to and from low Earth orbit.[1] Sierra plans to manufacture a fleet of the spaceplane.[2]
The Dream Chaser was originally started in 2004 as a project of SpaceDev, a company that was later acquired by the Sierra Nevada Corporation (SNC) in 2008.[3] In April 2021 the project was taken over by the Sierra Space Corporation (SSC), which at that time was spun off from the Sierra Nevada Corporation as its own fully independent company.
The cargo Dream Chaser is designed to resupply the International Space Station with both pressurized and unpressurized cargo. It is intended to be launched vertically on the Vulcan Centaur rocket[4] and autonomously land horizontally on conventional runways.[5] A proposed version to be operated by European Space Agency (ESA) would launch on an Arianespace vehicle.
The Dream Chaser concept and design is a descendant of the original NASA Space Shuttle program.[citation needed]
