The first crewed flight of the Boeing Starliner capsule has been delayed due to a rocket failure

(Reuters) – Boeing’s highly anticipated first crewed test flight of its new Starliner space capsule was called off for at least 24 hours due to a technical problem that launch teams could not resolve in time for the scheduled launch on Monday evening.

The final flight was canceled with less than two hours to go as the capsule prepared to launch from NASA’s Kennedy Space Center in Florida atop an Atlas V rocket supplied by United Launch Alliance, a joint venture of Boeing and Lockheed Martin.

Two years after the first uncrewed trip to the International Space Station (ISS), Boeing’s new Starliner astronaut capsule was ready for its first crewed test flight on Monday evening, after numerous delays.

Boeing’s Crew Space Transportation (CST)-100 Starliner spacecraft, developed in conjunction with NASA’s Commercial Crew Program, is designed to carry up to seven passengers, or a combination of crew and cargo, for travel to low Earth orbit.

Aboard the Starliner were NASA astronauts Barry “Butch” Wilmore, 61, a retired U.S. Navy captain, and Sunita “Suni” Williams, 58, a former Navy aviator and test pilot.

Shares of Boeing fell less than 1% in pre-market trading after the plane maker also faces a new FAA investigation into falsified 737 inspection data.

July 29, 2021 – An accident on the space station prompts NASA to postpone the launch of the Starliner.

August 3, 2021 – Boeing postpones a Starliner launch after a new glitch.

August 13, 2021 – Boeing returns the spacecraft to the factory to fix a valve problem, delaying the launch date.

May 20, 2022 – The new Starliner crew capsule docked with the International Space Station for the first time.

August 25, 2022 – Boeing aims for the first Starliner mission with astronauts in early 2023.

June 1, 2023 – Boeing says it is withdrawing from late preparations for its first crewed Starliner test flight into space, scheduled for July 2023, after discovering two safety-critical issues with the spacecraft.
