Elon Musk's SpaceX made history on Saturday with the launch of its first spaceflight carrying astronauts, which is also the first crewed launch from U.S. soil in nine years and marks the beginning of an era of private sector spaceflight.

This long-anticipated launch was originally scheduled for Wednesday, May 27, but mission leads opted to scrub it fewer than 20 minutes before the rocket was set to blast off. Following a tense day of dark clouds and even a tornado warning near the Cape Canaveral launchpad, the weather conditions were deemed an unacceptable threat to the safety of the mission and its astronauts.
