The launch of the CST-100 is now scheduled for December 17th.
Starliner rolled out of the Boeing Commercial Crew and Cargo Processing Facility at Kennedy Space Center on November 21.
The Commercial Crew Program is a more than $6 billion project aimed at ending NASA's reliance on the Russian space agency for rides to the station after the shuttle program ended in 2011.
Boeing's new CST-100 Starliner is now connected to the United Launch Alliance (ULA) Atlas V rocket that will launch the spacecraft on its first flight test to the International Space Station.More news: Luka Doncic stars as Mavericks destroy Golden State
With the end of NASA's space shuttle program in 2011, American astronauts, along with their global partners in the U.S. On-Orbit Segment (USOS) - the Canadian Space Agency, European Space Agency and Japan Aerospace and Exploration Agency - were left to hitch a ride on Soyuz rockets.
Five years ago, Boeing and SpaceX emerged as the big winners, racking up contracts now worth $4.3 billion and $2.5 billion, respectively, to fly six missions apiece to and from the space station. However, a recent report by the NASA Inspector General (IOG) states that a single seat on the Starliner could cost NASA up to $ 90 million. However, the aforementioned OIG report claimed both Boeing and SpaceX would end up launching crewed missions closer to summer 2020.
Boeing also seemed to taunt its competitors in the report as it stated; "Starliner flies on the most reliable lifter in the business, an Atlas V modified for human spaceflight safety by people with actual experience in the domain".
"Our team successfully completed the transport and mating of two incredible vehicles", said Boeing Starliner Vice President John Mulholland.More news: Intel ‘sincerely apologizes’ to customers for lingering CPU shortage
If all goes as planned and Boeing or SpaceX are certified and cleared for crewed missions, then the number of seats for the October launch won't be an issue.
"I am looking forward to the SpaceX announcement tomorrow. It's time to deliver", wrote Jim Bridenstine, NASA's big chief via Twitter.
Nonetheless, SpaceX have already performed the first test flight of its Crew Dragon spacecraft, when it headed to the ISS in March for a week-long stay before heading back to Earth.
Today Boeing said its mannequin is called Rosie the Rocketeer - a tribute to World War II's Rosie the Riveter that makes a fashion statement in the form of a red polka-dotted headscarf. The vehicle will one day carry astronauts to and from the International Space Station (ISS), but will first have to complete its maiden voyage.More news: Benzema mulling two-year Real Madrid extension
