Boeing Starliner launches 2 NASA astronauts into space in first piloted test flight

The third time proved to be the charm for NASA and Boeing, which successfully launched two astronauts into space Wednesday morning from Cape Canaveral, Florida.

Liftoff, which was scheduled for 10:52 a.m., occurred without a hitch. It is Boeing's first piloted test flight. 

The United Launch Alliance (ULA) Atlas V rocket and Boeing Starliner carrying astronauts Butch Wilmore and Suni Williams is heading for the International Space Station (ISS). The Starliner is expected to arrive at the space station after a flight of about 24 hours and dock with the orbiting research outpost some 250 miles above Earth.

"Suni and I, as we were traveling to the pad, we saw many American flags and many of you were waving flags at us," Wilmore said less than six minutes before the rocket launched. "And then as we reached the pad, we looked up and of course there's an American flag on the side of the white room, also one on the side of the rocket itself. We know that that represents unity and resilience and unified efforts for the common good. That's what Suni and I have witnessed this last month."

Wilmore and WIlliams will be at the ISS for about a week, testing "the Starliner spacecraft and its subsystems before NASA works to complete final certification of the transportation system for rotational missions to the orbiting laboratory as part of the agency’s Commercial Crew Program," NASA said.

Boeing had posted a mission update stating that engineers and technicians closed the hatch to the CST-100 Starliner after ensuring Wilmore and Williams were safely secured in their seats at 9:08 a.m. ET.

The last attempt to launch Boeing's Starliner spacecraft was scrubbed Saturday less than four minutes before blastoff from NASA'S Kennedy Space Center due to a ground system computer triggering an automatic abort command that shut down the launch sequence.

The first attempt to launch was May 6. NASA, Boeing and ULA scrubbed the opportunity "due to a suspect oxygen relief valve on the Atlas V rocket’s Centaur second stage," a launch attempt coverage advisory stated.

NASA's partnership with Boeing and SpaceX came about after space shuttles carrying astronauts retired. SpaceX has successfully been sending astronauts into space since 2020.

 

More than 256,000 people watched the launch on NASA's YouTube livestream alone. The launch was broadcast via other channels and feeds, as well.
