Today was supposed to be the big day for the historic first ever crewed mission of the Boeing Starliner to the International Space Station, but the launch was scrubbed just minutes before lift-off.
NASA posted on it's website:
NASA, Boeing, and ULA (United Launch Alliance) scrubbed today’s launch opportunity due to the computer ground launch sequencer not loading into the correct operational configuration after proceeding into terminal count. The ULA team is working to understand the cause. The next launch opportunity is Sunday, June 2, at 12:03 p.m. EDT for launch of NASA’s Boeing Crew Flight Test.
The ULA Atlas V rocket and Boeing’s Starliner spacecraft are in a safe configuration, and NASA astronauts Butch Wilmore and Suni Williams are preparing to exit the spacecraft.
