Before Saturday only the national space programs of Russia, the United States, and China had launched humans into orbit. Now, SpaceX—with NASA's funding and considerable help—has joined that exclusive club.
NASA, of course, has been sidelined in the human spaceflight game since 2011, when the space shuttle retired. Since then, NASA has relied on Russian Soyuz spacecraft for access to the station. When tensions between the United States and Russia in 2014, a senior Russian official who now heads the country's space program, Dmitry Rogozin, taunted NASA by suggesting the space agency use a trampoline to launch its astronauts.
At a post-flight news conference on Saturday, Musk quipped, “The trampoline is working."
