Coincidentally, two of the service module’s RCS thrusters as well as two OMAC engines and one of the crew module’s RCS thrusters malfunctioned during the second uncrewed test flight of Starliner in ...

Starliner's recently completed Crew Flight Test mission faced several technical problems in space. Will NASA certify the spacecraft for long-duration astronaut flights?

Alongside the 28 RCS thrusters are 20 “Orbital Maneuvering and Attitude Control” — or OMAC — thrusters, each of which has about 17 times the thrust of an RCS thruster.

Ground testing has linked the RCS thruster issue to overheating: Repeated thruster firings can apparently warm up the doghouses so much that some of their Teflon seals bulge, affecting propellant ...

Boeing's Starliner spacecraft will gently back away from the International Space Station Friday evening, then fire its balky thrusters to rapidly depart the vicinity of the orbiting lab and its ...

Such work included modeling studies and testing both in space (with Starliner) and on the ground (with a Starliner RCS thruster at NASA's White Sands Test Facility in New Mexico).

It delayed Crew-9 in order to perform ground testing at White Sands Test Facility in New Mexico, putting an identical RCS thruster through the same maneuvers that affected Starliner on orbit.

During Starliner’s perilous return to Earth, the capsule did have other types of thrusters meant to help the vehicle keep its orientation as it traveled through space. Alongside the 28 RCS thrusters ...
