NASA astronauts living aboard the International Space Station closed the hatch of Boeing’s CST-100 Starliner spacecraft at 3 p.m. EDT (12 p.m. PDT) Tuesday, May 25. The uncrewed spacecraft is scheduled to autonomously undock from the space station to begin the journey home at 2:36 p.m. EDT (11:36 a.m. PDT) Wednesday, May 25. NASA and Boeing are targeting 6:49 p.m. EDT (3:49 p.m. PDT) for the landing and conclusion of Orbital Flight Test-2, wrapping up a six-day mission testing the end-to-end capabilities of the Starliner system.

Teams are targeting White Sands Space Harbor at the U.S. Army’s White Sands Missile Range in New Mexico as the primary landing site, with a backup White Sands opportunity Friday, May 27. The spacecraft will return with more than 600 pounds of cargo, including Nitrogen Oxygen Recharge System reusable tanks that provide breathable air to station crew members. The tanks will be refurbished on Earth and sent back to the space station on a future flight.

Aboard the International Space Station, the unpiloted Boeing Starliner spacecraft hatch was closed and farewell remarks were given by NASA astronauts Kjell Lindgren, Bob Hines, Jessica Watkins and ESA (European Space Agency) astronaut Samantha Cristoforetti on May 24. Starliner is slated to undock from the space station on May 25 after completing a series of test objectives. Boeing’s Orbital Flight Test-2 (OFT-2) will land at White Sands Space Harbor, New Mexico. This test flight comes as a precursor to a future crewed Starliner test flight. Credit: NASA
