NASA has not been able to launch people into space since the space shuttle was retired in 2011. Since then, the USA has been buying seats on Russian missions to get American astronauts to the International Space Station (ISS).
As part of NASA's Commercial Crew Program, the next iteration of NASA's manned missions to space, SpaceX and Boeing are preparing for the final stages before their first launch. Then, SpaceX's Dragon will usher two NASA astronauts to orbit from Kennedy Space Center in December, a few months behind the original test schedule. However, all is not rosy because a recent report by the Aerospace Safety and Advisory Panel states the capsules may not be able to be certified because Boeing and SpaceX may not be able to meet the requirement for 1 possible fatal accident in 270 flights. Anyway, good luck to both companies and their passengers.
NASA last reported the schedule on October 5, 2017. It must rely on Russia to ferry crews back and forth to the ISS on Russian Soyuz spacecraft.
