For the first time in history, a private company has launched people to orbit from U.S. soil.
Why it matters: This SpaceX launch of its Crew Dragon capsule — in the midst of the coronavirus pandemic — marks the first time NASA astronauts have been sent to the International Space Station from U.S. soil since the end of the space shuttle program in 2011.
SpaceX plans to attempt to launch NASA astronauts to orbit for the first time on Saturday, if the weather cooperates.
Why it matters: If it works, this launch will mark the first time a private company has sent humans to orbit, and could be the beginning of the end of NASA's reliance on Russia for flights to and from the International Space Station.
