Boeing’s Crew Flight Test on Starliner Docks to Station

Boeing's Starliner spacecraft with two NASA astronauts aboard approaches the space station for an autonomous docking as it orbited 257 miles above the South Pacific Ocean. — Boeing’s Starliner spacecraft with two NASA astronauts aboard approaches the space station for an autonomous docking as it orbited 257 miles above the South Pacific Ocean.

NASA astronauts Butch Wilmore and Suni Williams, aboard Boeing’s Starliner spacecraft, successfully docked to the International Space Station at 1:34 p.m. EDT. Starliner launched on a United Launch Alliance Atlas V rocket at 10:52 a.m., June 5 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

During flight, Wilmore and Williams successfully performed manual piloting demonstrations of Starliner and completed a sleep period. Prior to crew sleep, mission teams identified three helium leaks in the spacecraft. One of these was previously discussed before flight along with a management plan, and the other two occured when the spacecraft arrived in orbit. To monitor and manage these leaks, the three helium manifolds were closed in flight during the crew’s sleep period and were all reopened ahead of rendezvous and docking operations. After docking, all Starliner manifolds are closed per normal plans.

As Starliner began its approach to the space station, five reaction control system thrusters failed off during flight. Mission teams performed a series of hot-fire tests which re-enabled four of the thrusters while the crew manually piloted the spacecraft at the station’s 200-meter hold point. After re-selecting four of the thrusters, Starliner had the fault tolerance required to approach the space station for docking. At the 10-meter hold point, the mission team completed system readiness evaluations and proceeded with docking.

Starliner’s hatch opening will begin about 3:20 p.m., with welcome remarks to follow.

NASA will continue coverage on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.

NASA will host a post-docking media conference at approximately 5 p.m. with the following participants:

NASA Associate Administrator Jim Free
Steve Stich, manager, NASA’s Commercial Crew Program
Jeff Arend, manager for systems engineering and integration, NASA’s International Space Station Office
Mark Nappi, vice president and program manager, Commercial Crew Program, Boeing
