A helium leak pushed back a planned launch to May 25. Boeing's program that would shuttle astronauts to and from the International Space Station has been plagued with problems.

The US Air Force is imposing financial penalties on the United Launch Alliance, the Lockheed Martin Corp.- Boeing Co. joint venture, over delays of two military satellite launches this year, according to the service.

Days after Starliner teams reported a small helium leak in the spacecraft’s service module, the target date for the highly anticipated mission has moved once more.

NASA, Boeing, and the United Launch Alliance (ULA) continue preparation for NASA's Boeing Crew Flight Test bound for the International Space Station.

The historic first crewed launch of Boeing Co.’s Starliner spacecraft will now take place no earlier than May 25, after the initial launch attempt was scrubbed earlier this month. “Teams will use the additional time to finalize next steps that address a stable helium leak on the #Starliner service module,

The first crewed flight test of Boeing's Starliner space taxi has been reset for no earlier than May 25 to leave more time for ground tests.

Ongoing work to resolve a persistent helium leak has pushed the first piloted Starliner flight back at least four more days, to May 25.

The first crewed mission of Boeing's new Starliner spacecraft has been pushed back by an additional four days, to May 25.

NASA and Boeing need more time to make sure a helium leak on its CST-100 Starliner is low enough risk to send humans into space. So the launch of NASA astronauts Butch Wilmore and Suni Williams has now been pushed to May 25 targeting a 3:09 p.
