Ever since the US shuttle program ended in 2011, astronauts - both American and those from other nations - have been dependent on the Russian Soyuz spacecraft to go to and from the International Space Station (ISS). The reliance, which costs NASA $70 million for each trip, is expensive and also leaves astronauts in danger of being stranded in the event of a spacecraft malfunction, like the one experienced in October 2018. Now, thanks to SpaceX's successful Crew Dragon test mission, astronauts may soon have an alternate, more affordable, mode of transportation to the ISS.
