Q&A with Marc Eisenberg, Orbcomm’s chief executive

Live coverage of the countdown and launch of a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center with the Koreasat 5A communications satellite. Including a live view of the launch pad (members only).

Assuming SpaceX’s plans come to fruition, a Falcon 9 flight from Cape Canaveral on Sunday will end with a vertical rocket-assisted landing at an abandoned Cold War-era launch facility a few miles away.

The third launch of China’s heavy-lift Long March 5 rocket successfully delivered its satellite payload to orbit Friday, validating engine design changes after a failure on the Long March 5’s second flight, and clearing the way for the launch of a Chinese Mars rover and lunar sample return mission in 2020.
