Summary
CST-100 Starliner Orbital Flight Test launched on an United Launch Alliance Atlas V N22 from Space Launch Complex 41, Cape Canaveral SFS, FL, USA on December 20, 2019. It was United Launch Alliance's 137th launch, 5th this year and humanity's 5,919th orbital launch attempt. It was the 1st Atlas V N22 flight. The payload was bound for low Earth orbit (LEO). It reached a 83 × 198 km orbit inclined 51.6°. One crew member flew: Rosie the Astronaut. The spacecraft was Starliner Calypso (3). One object from this launch is catalogued.

About this launch
This is the first test flight of Starliner spacecraft to the International Space Station. Although Atlas V and Centaur upper stage successfully put Starliner into planned trajectory, the spacecraft was unable to perform a nominal orbital insertion. Preliminary analysis indicate that Mission Elapsed Time (MET) system error led to Starliner burning more fuel than expected. Spacecraft is healthy and in stable orbit, but won't be able to reach and dock with ISS. Landing at White Sands Facility is planned on Dec 22.
