The second try and ship Boeing’s Starliner crew capsule into orbit was scrubbed simply minutes earlier than it was set to launch.
NASA astronauts Barry “Butch” Wilmore and Sunita Williams had been strapped into the corporate’s Starline capsule and awaiting liftoff when the countdown was halted at three minutes and 50 seconds. The ship was initially scheduled for liftoff from pad 41 on the Cape Canaveral House Pressure Station at 12:25 p.m. EDT, roughly the second Earth’s rotation carried the pad into alignment with the area station’s orbit.
With solely a break up second to take off Saturday afternoon, there was no time to work the newest bother and every part was known as off.
The following potential launch window is Sunday.

Earlier story
A United Launch Alliance Atlas 5 rocket was fueled for a second launch strive Saturday to spice up Boeing’s Starliner crew capsule into orbit on the oft-delayed crew capsule’s first piloted check flight, a voyage to the Worldwide House Station.
With NASA astronauts Barry “Butch” Wilmore and Sunita Williams monitoring the ship’s automated ascent, the workhorse Atlas 5 was scheduled for liftoff from pad 41 on the Cape Canaveral House Pressure Station at 12:25 p.m. EDT, roughly the second Earth’s rotation carried the pad into alignment with the area station’s orbit.
United Launch Alliance
If all goes nicely, the Starliner will meet up with the station Sunday and dock on the lab’s ahead port round 1:50 p.m. Wilmore and Williams plan to return to Earth on June 10.
The long-awaited flight would be the first piloted launch of an Atlas 5 and the primary for the Atlas household of rockets since astronaut Gordon Cooper took off only a few miles away on the Mercury program’s last flight 61 years in the past.
Likewise, it will likely be the primary piloted flight of the Starliner, Boeing’s reply to SpaceX’s Crew Dragon, an already operational, inexpensive spacecraft that has carried 50 astronauts, cosmonauts and civilians into orbit in 13 flights, 12 of them to the area station, since an preliminary piloted check flight in Might 2020.
NASA
NASA funded the event of each spacecraft to make sure the company may launch crews to the outpost even when one firm’s ferry ship had been grounded for any cause.
Already operating years not on time due to funds shortfalls and quite a lot of technical issues that price Boeing greater than $1 billion to right, NASA had hoped to get the Starliner into orbit on Might 6. However the launch was scrubbed when United Launch Alliance engineers detected bother with a pressure-relief valve within the rocket’s Centaur higher stage.
The Atlas 5 was hauled off the pad and again to ULA’s Vertical Integration Facility the place the Centaur valve was shortly changed. However within the wake of the launch scrub, Boeing engineers noticed indicators of a small helium leak within the Starliner’s propulsion system.
The leak was traced to a flange in plumbing that delivered pressurized helium to drive one particular response management system jet within the Starliner’s service module. The leak was characterised as “very small,” however engineers wanted to point out it will not drastically worsen in flight and trigger issues for different thrusters.
After intensive evaluation and testing, mission managers concluded the spacecraft might be safely launched as is, saying that even when the leak fee was 100 instances worse than to date noticed, it will not pose a danger to the crew or the mission.
