Well … that depends on who you ask.
Of course NASA wants all missions to be successful. During a post-landing press conference, the touchdown was described as a “bullseye landing”.
When asked about the safety of the capsule, NASA said “it would have been a safe, successful landing with the crew on board”.
But then some negatives had to be addressed, like another thruster failing during the descent and temporary blackout of the guidance system.
So will Starliner fly again or will the program become mothballed? Only time will tell.
