Boeing’s Starliner starts leaking on its way to International Space Station with Nasa astronauts on board

New passenger capsule has run into a series of problems ahead of launch

Boeing’s troubled Starliner space capsule has developed a series of links as it carries Nasa astronauts to the International Space Station.

The Starliner capsule already had one small helium leak when it rocketed into orbit Wednesday. Boeing and NASA managers were confident they could manage the propulsion system despite the problem and that more leaks were unlikely.

But just hours into the flight, two more leaks cropped up. There was no immediate word on the size of these new leaks.

Despite the issue, mission managers pressed ahead for a midday docking with the space station while continuing to monitor the issue. Mission Control said the leaks were not expected to impact the rendezvous.

Helium is used to pressurize the fuel lines of Starliner’s thrusters, which are essential for maneuvering. Before liftoff, engineers devised a plan to work around any additional leaks in the system. A faulty rubber seal, no bigger than a shirt button, is believed responsible for the original leak.

After the space shuttles retired, NASA hired Boeing and SpaceX to ferry astronauts to and from the space station. SpaceX’s taxi service began in 2020. Boeing was supposed to start around the same time, but was held up for years by safety concerns and other troubles.

Boeing finally rocketed from Florida on Wednesday with NASA test pilots Butch Wilmore and Suni Williams.

Boeing plans to keep Starliner at the space station for at least eight days before guiding it to a landing in the western US.
