We’re now just a day away from the highly anticipated test flight of Boeing’s CST-100 Starliner spacecraft to the International Space Station (ISS).
The uncrewed Orbital Flight Test-2 (OFT-2) is considered high-stakes as it follows a failed test mission in 2019 when the spacecraft was unable to enter the correct orbit to take it to the ISS. Following a thorough investigation, software issues were pinpointed as the cause.
A second flight attempt in August last year failed to get off the ground after an issue was spotted with valves linked to Starliner’s propulsion system on its service module.
Ahead of Thursday’s launch from Cape Canaveral in Florida, the mission team rolled the United Launch Alliance Atlas V rocket and Starliner spacecraft from the Kennedy Space Center’s Vertical Integration Facility to the launchpad a short distance away.
Boeing posted a video (below) that includes a time-lapse showing the space vehicle heading to the launchpad on Wednesday.

If everything goes to plan, the Starliner spacecraft will dock with the ISS about 24 hours after launch. It will stay at the orbital outpost for up to 10 days before returning to Earth in a parachute-assisted landing in New Mexico.
“The flight test, which includes orbital maneuvering, International Space Station rendezvous, docking, undocking, and landing operations, will validate all of the critical systems and capabilities ahead of Boeing’s first flight carrying astronauts to and from the ISS,” Boeing said in a message posted on its website.
The crewed test flight could take place in the next 12 months and would send the Starliner on the same route to and from the space station. A successful crewed mission would allow NASA to use the spacecraft for future astronaut flights to and from the ISS, giving it another transportation option alongside SpaceX’s Crew Dragon capsule, which has been conducting regular astronaut flights since the summer of 2020.
