Boeing’s CST-100 Starliner did not reach its planned orbit and dock to the International Space Station last month but completed test objectives related to NASA’s Commercial Crew Program including a successful launch of the first human-rated United Launch Alliance (ULA) Atlas V rocket; testing of the propulsion systems, communications, and docking system; and tracker alignments using its navigation system.

The Starliner will be refurbished for Boeing’s first operational crewed mission following the Crew Flight Test.
