An Atlas 5 rocket, carrying NASA astronauts Barry 'Butch' Wilmore and Sunita Williams for Boeing's Starliner spacecraft, was scheduled for a historic launch on Monday night from Cape Canaveral Space Force Station in Florida. However, the mission was scrubbed just two hours before takeoff due to an issue with a valve in the rocket's upper stage.
The Starliner spacecraft is set to be the final major milestone before NASA deems Boeing's spacecraft ready for routine operations as part of the Commercial Crew Program. Williams, who will become the first woman ever to join such a mission, and Wilmore were in the process of strapping in for launch when they received news of the scrub.
The Atlas V rocket, built by United Launch Alliance (ULA), has been a workhorse vehicle used for numerous historic missions including Titan rockets, New Horizons deep space probe, Voyager spacecraft, and Curiosity Mars rover. The Starliner launch was expected to mark the next chapter in American space exploration.
Despite the setback, NASA officials remain optimistic about a potential relaunch. Possible launch times include Tuesday at 10:11 p.m. ET as well as other dates yet to be determined.
The Starliner crew members, Wilmore and Williams, have extensive backgrounds in aviation and space travel. Wilmore is a U.S Navy captain, fighter pilot, and test pilot with over 8000 hours of flight time. Williams was originally a helicopter test pilot before switching to flying jets.
The launch pad at Cape Canaveral Space Force Station has been the site for many historic missions throughout history and continues to be an important hub for space exploration.
