American aerospace giant Boeing's Starliner capsule was heading for the International Space Station Thursday, in a critical uncrewed test flight that followed years of failures and false starts.
The spacecraft encountered some propulsion troubles early in its journey, with two thrusters responsible for orbital maneuvering failing for unclear reasons—but NASA officials said the mission remained on track.
At a post-launch press conference, senior NASA official Steve Sitch said: "Overall, the spacecraft is doing really well," but he also flagged two anomalies that engineers were now working to understand.
The first was that two out of 12 orbital maneuvering and attitude control (OMAC) thrusters located on Starliner's aft side had initially fired but then shut down, forcing a third to take up their slack.
The second issue was that a device known as a sublimator responsible for cooling the spacecraft was initially slow to get started.
