Starliner reaches proper orbit despite thruster problems
Unbelievable: During the post-launch press conference last night Boeing officials revealed that, though the final burn to get Boeing’s Starliner capsule into orbit using its own thrusters succeeded, the thrusters did not function as planned.
Boeing Vice President Mark Nappi said a Starliner thruster failed after firing for one second as the spacecraft made a burn to enter orbit after separating from its Atlas V launch vehicle. The flight software switched to a second thruster, which fired for 25 seconds before shutting down prematurely. A third thruster took over and completed the firing, Nappi said.
The thrusters were made by Aerojet Rocketdyne, which also made the valves that did not work in the previous launch attempt in the summer of 2021. Whether the two problems are related is not known at this time.
A NASA official also noted that a cooling unit on the spacecraft operated “sluggishly during ascent,” but began working correctly once in orbit.
Right now NASA and Boeing are planning to proceed with the docking on ISS tonight at 7:10 pm (Eastern). It appears that though two thrusters have failed, they have ten more thrusters that can be used for further maneuvers throughout the mission. Furthermore, these thrusters are not used during the actual rendezvous and docking.
The live stream of the docking goes live at 3:30 pm (Eastern), and is embedded below. Until then enjoy NASA propaganda, some of it might be of interest.
Update: NASA has cut off coverage of the docking on the channel I had embedded previously. I have now embedded an active live feed.
