Video: Launch camera replays from Friday’s Falcon 9 blastoff

A commercial Dragon cargo capsule will remain at the International Space Station until Saturday, three days later than previously planned due to high sea states observed by the SpaceX recovery team in the spaceship’s splashdown zone in the Pacific Ocean.

For the second day running, computers automatically aborted a Falcon 9 launch countdown Monday at NASA’s Kennedy Space Center in Florida in the final seconds before liftoff with the Intelsat 35e communications satellite.

SpaceX chief executive Elon Musk will unveil his plans for human missions to Mars on Tuesday in a presentation at the International Astronautical Congress in Guadalajara, Mexico. Watch the speech live at 2:30 p.m. EDT (1830 GMT).
