If you were up early this morning at around 12:45 a.m., you may have caught the spectacular lift-off of the unmanned Falcon rocket towards space, streaking through darkness into orbit.
Elon Musk's SpaceX company is sending a critical space station docking port for astronauts towards the International Space Station.
The Dragon capsule is on a two-day pursuit, with arrival expected Wednesday.
The payload on the Dragon cargo ship is nearly 5,000 pounds of supplies for the ISS, a DNA decoder for high-flying genetic research, and the docking ring.
NASA needs to setup the new docking ring before Americans can fly up in crew capsules debuting next year.
About ten minutes after lift-off, SpaceX successfully landed the booster rocket on a launch pad at Cape Canaveral, only the second time they've done so at the Cape.
The last three landings of a Falcon 9 rocket were on a barge at sea.
