Boeing won't start flying operational crew missions with Starliner until a year from now.
Astronauts Butch Wilmore and Suni Williams have been in space for 51 days, six weeks longer than originally planned, as engineers on the groundwork through problems with Starliner's propulsion system. This thruster was taken from a set of hardware slated to fly on a future Starlink mission, and engineers put it through a stress test, firing it numerous times to replicate the sequence of pulses it would see in flight. Starliner's flight computer shut off five of the spacecraft's 28 reaction control system thrusters, produced by Aerojet Rocketdyne, during the rendezvous with the space station last month.
