SSC Demo-1, also known as Dream Chaser Demo-1, is the planned first flight of the Sierra Space robotic spacecraft Dream Chaser to low Earth orbit under the CRS-2 contract with NASA. Originally scheduled to go to the International Space Station (ISS) in 2025, In September 2025, NASA announced the mission would not visit the ISS and instead launch in late 2026.
The Dream Chaser division of the Sierra Nevada Corporation (SNC) was spun-off in April 2021, creating the fully independent 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. 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.
