Since 1961, NASA (National Aeronautics and Space Administration) has sent six different classes of crewed spacecraft into space. Can you name them all in one minute?
'Space' is defined here as the Kármán line (the boundary between Earth's atmosphere and outer space, an altitude of 100 kilometres or 62 miles). Although the North American X-15 breached the Kármán line on several ocassions, is not included in this list as it was designed as an aircraft.
While they may not have had crew on them, both Starliner and Orion are crew-rated capsules built for NASA that have each flown twice (even though Starliner had quite a large glitch on its first flight). And technically ULA and SpaceX "send" Dragon and Starliner to space, plus Orion on EFT-1.
As they have yet to bring people to space, the Starliner and Orion are not on this list yet for that simple reason. They are still considered 'in development'. Crew Dragon has been developed by a private company, but it flies under the NASA Commercial Crew Program banner.
