Image credit: NASA/Joel KowskyStarliner and its rocket ride were delayed by bad weather forecasts on the Space Coast and made the difficult trip back to their processing plant today.Representatives of ULA wrote today via Twitter that "for the protection and #AtlasV" and "to avoid inclement weather", they were returning to the Vertical Integration Facility, (VIF).Starliner's next launch will be Orbital Flight Test 2 ("OFT-2"), a critical uncrewed test flight towards the space station. In December 2019, Boeing had already attempted this mission. Starliner was unable to navigate correctly and got stuck in an incorrect orbit. It had to return to Earth, without ever meeting with the orbiting laboratory.If everything goes according to plan, Starliner could carry astronauts for first time. This milestone could be reached by the end, Boeing and NASA officials said.Starliner has been developed by Boeing using funding from NASA's Commercial Crew Program. SpaceX was also awarded a similar deal. Elon Musk's company, using its Crew Dragon capsule to launch astronauts to NASA three times. It also used the Falcon 9 rocket and Falcon 9 rocket for two more operational missions.Crew-2, the most recent SpaceX mission, is currently underway. It was launched in April, and it is expected to be completed in November.
