Scrubbed launches for Boeing's Starliner spacecraft, built to send a pair of astronauts to the International Space Station, have become a regular event recently.
The June 1 launch of the Starliner to transport two NASA astronauts, and former Navy pilots, Barry "Butch" Wilmore and Sunita "Suni" Williams,to and from the ISS, was halted a few minutes from liftoff and a June 2 launch window bypassed.
Now, as of Tuesday afternoon, NASA was looking to attempt a launch on Wednesday, June 5, at 10:52 a.m. ET.
This comes after several delays including launches scrubbed in May due to technical issues including an oxygen leak and a helium leak from the capsule's propulsion system.
Boeing won NASA contract in 2014
These recent delays aren't the only challenges Boeing has faced in getting Starliner into space since NASA awarded it $4.2 billion as part of the space agency's goal of developing private industry partners to transport astronauts to and from the space station.
At the time, competitor SpaceX got $2.6 billion. Each companies' funding has grown to $4.8 billion and $3.1 billion, respectively, according to NASA.
While SpaceX has reliably been transporting astronauts and supplies to the ISS, Boeing's project is years behind schedule and has racked up $1.5 billion in unplanned development costs, Reuters reported.

- October 2011: Boeing wraps up wind-tunnel tests on a scale version of what would become Starliner, Space.com reported.
Boeing looks for success after bumpy 2024
A successful Starliner mission could help Boeing rebound in the public eye from ongoing issues with its 737 Max jets, including the grounding of the planes after an Alaska Airlines 737 Max lost a door plug during a flight in January.
“It’s been hugely embarrassing for Boeing,” Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told Wired in May. “It fits in with the general narrative of Boeing having lost its way."
Boeing is a longtime NASA contractor, having collaborated on the Saturn V rocket in the Apollo program and the Space Shuttle program, according to Space.com.
