CAPE CANAVERAL, Fla. — Boeing’s new capsule arrived on the Worldwide House Station on Thursday, delayed by last-minute thruster hassle that just about derailed the docking for this primary check flight with astronauts.
The 260-mile-high (420-kilometer-high) linkup over the Indian Ocean culminated greater than a day of constant drama for Boeing’s astronaut flight debut carrying NASA check pilots Butch Wilmore and Suni Williams.
Boeing plans to maintain Starliner on the area station for a minimum of eight days earlier than guiding it to a touchdown within the western U.S.
“Good to be hooked up to the massive metropolis within the sky,” Wilmore mentioned as soon as the hooks between the 2 spacecraft had been tight.
Williams entered the area station first, dancing on the way in which in to music. Wilmore adopted, snapping his fingers. They embraced the seven area station residents.
“It was such an awesome welcome, a little bit dance occasion,” mentioned Williams. “That’s the way in which to get issues going.”
The Starliner capsule already had one small helium leak when it rocketed into orbit with two NASA astronauts Wednesday. Boeing and NASA managers had been assured they might handle the propulsion system regardless of the issue and that extra leaks had been unlikely. However simply hours into the flight, two extra leaks cropped up and one other was found after docking.
Later, 5 of the capsule’s 28 thrusters went down. The astronauts managed to restart 4 of them, offering sufficient security margin to proceed. By then, Starliner had handed up the primary docking alternative and circled the world for an additional hour alongside the station earlier than transferring in.
The thrusters issues had been unrelated to the helium leaks, NASA’s industrial crew program supervisor Steve Stich mentioned after the docking.
Going ahead within the flight, “now we have some instruments in our software equipment to handle this,” Stich mentioned.
Earlier within the day, earlier than the thrusters malfunctioned, officers careworn that the helium leaks posed no issues of safety for the astronauts or the mission.
Helium is used to pressurize the gasoline traces of Starliner’s thrusters, that are important for maneuvering. Earlier than liftoff, engineers devised a plan to work round any extra leaks within the system. A defective rubber seal, no greater than a shirt button, is believed answerable for the unique leak.
Boeing program supervisor Mark Nappi mentioned there must be loads of helium in reserve for the journey dwelling.
After the area shuttles retired, NASA employed Boeing and SpaceX to ferry astronauts to and from the area station. SpaceX’s taxi service started in 2020. Boeing was supposed to begin across the identical time, however was held up for years by security issues and different troubles.
Stich mentioned not one of the issues up to now would require a repeat of an astronaut check flight earlier than certifying the capsule for normal use.
