(Reuters) – NASA will return Boeing (NYSE:)’s faulty Starliner capsule to Earth without astronauts Butch Wilmore and Suni Williams, who will return to Earth on a SpaceX vehicle early next year, NASA chief Bill Nelson said on Saturday.
Starliner launched its first two astronauts, both former military test pilots, into space on June 5 as a crucial test before it can receive NASA approval for routine flights. But what was supposed to be an eight-day mission docked to the ISS has been drawn out by months after the capsule sprang leaks and some of its thrusters failed.
Here’s a rundown of key events in Starliner’s journey to space over the past few years:
Sept. 4, 2015 – Boeing takes the wraps off an assembly plant for its first line of commercial spaceships, which NASA plans to use to fly crews to the ISS.
Nov. 4, 2019 – Boeing says one of three parachutes failed to open during a crucial unmanned test of the Starliner.
Dec. 20, 2019 – Boeing successfully launches its new astronaut capsule on an uncrewed debut journey to the ISS.
Dec. 22, 2019 – The spacecraft makes a “bullseye” landing in the New Mexico desert.
Jan. 7, 2020 – NASA and Boeing investigate a software glitch that prevented the unmanned capsule from reaching the ISS in its Dec. 2019 flight.
Feb. 6, 2020 – The NASA review panel says Boeing narrowly missed a “catastrophic failure” during its December flight test.
Aug. 25, 2020 – The first Starliner crewed mission is tentatively slated for 2021, with Boeing aiming to complete software and test hardware production development.
Oct. 7, 2020 – The chief astronaut for Starliner’s crewed flight to the ISS, Chris Ferguson, steps down from the job, citing family priorities. He is replaced by Wilmore.
July 29, 2021 – A space station mishap prompts NASA to postpone the launch of the Starliner.
Aug. 3, 2021 – Boeing postpones Starliner launch after new glitch.
Aug. 13, 2021 – Boeing returns the spacecraft to the factory to resolve a valve issue, delaying the launch date until at least mid-October if not later.
May 19, 2022 – The Starliner capsule launches on a do-over uncrewed test flight bound for the ISS.
May 20, 2022 – The Starliner capsule, without astronauts onboard, docked for the first time with the ISS.
Aug 25, 2022 – Boeing announces it is targeting early 2023 for the first Starliner mission carrying astronauts.
June 1, 2023 – Boeing says it is standing down from late preparations for its first crewed Starliner test flight to space, which was planned for July 2023, after it discovered two safety-critical issues with the spacecraft.
May 3, 2024 – Boeing poised to send the first Starliner space capsule with a crew of humans into orbit the following week, after a year’s delay.
May 6, 2024 – The first crewed test flight of the new Starliner space capsule was postponed after the planned May 6 launch countdown was halted over a fault with the Atlas (NYSE:) V rocket.
May 7, 2024 – NASA says new targeted launch date for the mission was set to May 17 at the earliest.
May 14, 2024 – Boeing says the Starliner mission had been delayed again – until at least May 21 – over an issue with the spacecraft’s propulsion system.
May 17, 2024 – NASA and Boeing delayed the launch of the Starliner crew capsule again to check helium leak, targeting May 25.
May 21, 2024 – NASA again delayed the debut crew flight to spend more time evaluating the helium leak in the spacecraft’s propulsion system.
May 22, 2024 – NASA and Boeing target June 1 for the launch.
June 1, 2024 – A second attempt at launching the Starliner with astronauts on board was automatically halted with minutes to go before liftoff by a computer-abort system.
June 2, 2024 – Boeing and NASA target June 5 for the launch.
June 5, 2024 – The Starliner astronaut capsule was successfully launched from Florida with two astronauts aboard, with docking with the ISS scheduled for June 6.
June 6, 2024 – The Starliner capsule and an inaugural two-member NASA crew safely docked with the International Space Station.
June 11, 2024 – NASA and Boeing say they expect the Starliner capsule to return as soon as June 18, later than a previously scheduled return, citing fixes to faulty components on the capsule, and weather conditions among others.
June 21, 2024 – NASA further postponed the Starliner’s return to Earth, to allow more time for review of technical issues encountered.
June 27, 2024 – NASA says it would continue to evaluate Starliner’s propulsion system performance along with Boeing.
Aug 7, 2024 – NASA says the two astronauts could return on SpaceX’s Crew Dragon in February 2025 if Starliner is still deemed unsafe to return to Earth.
Aug 24, 2024 – The Starliner capsule is returning to Earth without astronauts Butch Wilmore and Suni Williams aboard, after NASA chief Bill Nelson said the duo will need to return on a SpaceX vehicle early next year.
