About the CST-100 Starliner Crewed Flight Test Mission
| Type | Test Flight |
|---|---|
| Orbit | Low Earth Orbit |
| Launch Cost | $110,000,000 |
This is the first crewed test flight of Starliner spacecraft. It will carry NASA astronauts Barry Wilmore and
Suni Williams to the International Space Station.
This mission is part of NASA's Commercial Crew Program, a partnership with private companies like SpaceX to safely transport astronauts to and from the International Space Station. Using the SpaceX Crew Dragon spacecraft and Falcon 9 rocket, the program has restored American human spaceflight capability and enabled routine crewed missions to low Earth orbit.
