The climb

Reaches 157 km up and 3,035 km downrange in the 12 minutes after liftoff.
0 80 160 01.6k3.2k km up km downrange Separation T+2:31

First stage Second stage

Simulated from the published flight plan. The climb flattens as the rocket pitches over to build sideways speed, which is why a launch stays visible so far from the pad. A dashed line is a stage that separates and flies back down, either to the pad or to a ship waiting downrange.

Going to watch it in person? Flyby's Pathfinder points your camera at the pad, so you are not stood there guessing which one it goes up from. It puts this same climb on a globe you can turn, too.

The operator

SpaceX

Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
