(Washington) The ship’s first crewed flight Starliner of Boeing was pushed back to May 17, NASA announced Tuesday, the day after a postponement decided just before takeoff due to a technical problem.
A takeoff attempt could take place “not before 6:16 p.m., Friday, May 17,” while a repair is made, the American space agency wrote in a press release.
This postponement hits a program marked by a series of setbacks, between unpleasant surprises and successive postponements.
Monday, the ship Starliner of Boeing was to, finally and for the first time, take off with astronauts on board, heading for the International Space Station, and thus join the very private club of spaceships that have transported humans.
But around two hours before the scheduled launch time, and while the two American astronauts were installed in the capsule, the takeoff was canceled: an anomaly was identified on a valve of the rocket Atlas V which should propel the capsule Starliner in orbit.
In the evening, the date of Friday May 10 was mentioned for takeoff.
But additional analysis showed that the valve in question actually needs to be replaced, a job that requires the rocket to be returned to its hangar.
The two astronauts, Butch Wilmore and Suni Williams, will remain isolated in the meantime, NASA said.
Boeing is playing big on this final test mission, which should allow it to demonstrate that its ship is safe before starting regular missions to the Space Station (ISS) – four years behind SpaceX.
For NASA, which ordered this vehicle ten years ago, the stakes are also high: having a second vehicle in addition to that of SpaceX to transport American astronauts should make it possible to better respond to “different emergency scenarios”. , for example in the event of a problem on one of the ships.
