SSC Demo-1, also known as Dream Chaser Demo-1, is the planned first flight of the Sierra Space robotic resupply spacecraft Dream Chaser to the International Space Station (ISS) under the CRS-2 contract with NASA. The demonstration mission is planned for launch no earlier than 2025.[2][4]
In April 2021 the Dream Chaser division of the Sierra Nevada Corporation (SNC) was spun-off, creating the new fully independent company, the Sierra Space Corporation (SSC), which assumed full oversight over the Dream Chaser program. The company developed a new reusable spacecraft to provide commercial cargo resupply services to the International Space Station (ISS), based on decades of lifting body programs. Under the Commercial Orbital Transportation System (COTS) program, the company designed Dream Chaser with industrial partner Lockheed Martin.
The company also designed the accompanying Shooting Star cargo module with subcontractor Applied Composites.[5] At the end of mission, the Shooting Star will destructively reenter the atmosphere and the Dream Chaser will land at the Kennedy Space Center's Shuttle Landing Facility.
