SpaceX Is Sending Its First Crew-Ready Capsule to the ISS

On Saturday, SpaceX is taking its most ambitious step yet toward launching people into space. It's not sending anyone with a pulse just yet, but this upcoming launch is still a high-consequence event. In the wee hours of the morning on March 2, SpaceX's shiny new astronaut taxi--dubbed Crew Dragon--will take to the skies, bound for the International Space Station. The flight, officially known as Demo Mission-1 (or DM-1), stars an upgraded version of SpaceX's Dragon cargo craft. SpaceX has always intended for its Dragon capsules to ferry humans, but every SpaceX Dragon capsule launched so far has only shuttled cargo to and from the ISS.
