Boeing and NASA are transferring ahead with the launch of the corporate’s Starliner capsule, set to hold U.S. astronauts for the primary time, regardless of a “stable” leak within the spacecraft’s propulsion system.
“We are comfortable with the causes that we’ve identified for this specific leak,” Mark Nappi, Boeing vice chairman and supervisor of the corporate’s Business Crew program, stated throughout a press convention on Friday.
“We know we can manage this [leak], so this is really not a safety of flight issue,” Nappi added.
Boeing is now focusing on June 1 for the primary crewed launch of its spacecraft, with backup alternatives on June 2, June 5 and June 6.
The mission, generally known as the Starliner Crew Flight Check, is meant to function the ultimate main improvement check of the capsule by delivering a pair of NASA astronauts to and from the Worldwide Area Station earlier than flying routine missions.
Starliner’s crew debut has been delayed by years, with SpaceX’s competing Dragon capsule flying astronauts for NASA often since 2020 beneath the company’s Business Crew program. Up to now, Boeing has eaten $1.5 billion in prices resulting from Starliner setbacks, along with practically $5 billion of NASA improvement funds.
Boeing’s Starliner spacecraft is seen earlier than docking with the Worldwide Area Station on Might 20, 2022 in the course of the uncrewed OFT-2 mission.

NASA and Boeing known as off a launch try on Might 6 about two hours earlier than liftoff resulting from a difficulty detected with the Atlas V rocket that can carry Starliner into orbit. Atlas V is constructed and operated by United Launch Alliance, or ULA, a three way partnership of Boeing and Lockheed Martin.
In the course of the press convention Friday, a ULA official famous that the rocket’s problematic valve was changed per week after the launch was postponed.
However after calling off the launch try, a “small” helium leak with Starliner was recognized, inflicting Boeing and NASA to start new assessments of the capsule and its security for the mission. NASA Affiliate Administrator Ken Bowersox, one of many company’s most senior officers, defined to the press on Friday that “it’s taken a while for us to be ready to discuss” the helium leak drawback.
“It’s so complicated. There’s so many things going on. We really just needed to work through it as a team,” Bowersox stated.
After evaluation, NASA and Boeing imagine the supply of the leak is a seal in one of many flanges of the spacecraft’s helium propulsion system. In testing after the Might 6 postponement, NASA’s Business Crew Program supervisor Steve Stich stated that groups “have seen that the leak rate isn’t changing.”
Stich defined that the plan is to observe the leak within the lead-up to launch and, after reaching the Worldwide Area Station, reassess the leak fee.
“We don’t expect the other [seals] to leak, and I think that’s a confidence that we have,” Stich stated.
Stich additionally emphasised that NASA has “flown vehicles with small helium leaks” earlier than, together with “a couple of cases” from missions flown by the Area Shuttle and SpaceX’s Dragon.
NASA, Boeing and ULA will maintain one other evaluate on Might 29 to evaluate the leak. They plan to roll the rocket and capsule out to the launch pad on Might 30 for the June 1 try.
