Boeing Space ’s Starliner ballistic capsule save its first crew to the International Space Station ( ISS ) in early June in a mission that was supposed to last about eight days .

But as itapproached the ISS on June 6 , trouble emerged with some of the Starliner ’s pusher . The pusher are important as they hold the orientation of the ballistic capsule and will therefore play a crucial role in channelize the Starliner toward its reentry into Earth ’s atmosphere when the vehicle ultimately sic off for place .

So implicated has NASA been about the functionality of the thruster that it adjudicate to extend the mission while it carried out investigative work into what happened , and to see if anything needs to be done — or can be done — to counterbalance the yield .

It ’s think that the two Starliner crew members — NASA astronauts Suni Williams and Butch Wilmore — have had their foreign mission stretch out until further notice .

NASA is get quick to offer another update on the mission — and possibly a date for the Starliner ’s homecoming — at 11:30 a.m. ET on Thursday , July 25 . Folks concerned in listening in can do sovia the agency ’s web site .

Participating in the metier issue will be Steve Stich , managing director of NASA ’s Commercial Crew Program , and Mark Nappi , vice president and program manager of Boeing ’s Commercial Crew Program .

As part of drive to well understand the thruster issue , NASA and Boeing recently completed ground hot fire examination of a Starliner reaction ascendency organisation thruster at White Sands Test Facility in New Mexico .

“ The examination serial involved firing the railway locomotive through similar in - flight conditions the spacecraft experienced during its overture to the space place , as well as various stress character firings for what is await during Starliner ’s undocking and the deorbit burn that will position the spacecraft for a landing in the Southwestern U.S.,”NASA saidon its website . “ Teams are psychoanalyse the datum from these test , and leadership be after to discuss initial finding during the call . ”

The Starliner foreign mission is an ending - to - remainder test of the spacecraft ’s scheme . Once it receive back to Earth , NASA will assess the mission to see if it can begin the process of certifying Starliner for rotational flights to and from the quad place , yield it another pick for crew mission alongside SpaceX ’s Crew Dragon spacecraft .
