Falcon Heavy hot fire as seen from Kennedy Space Center Press Site

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 chief technology officer of SES, operator of the world’s largest commercial geostationary satellite fleet, spoke with reporters on the eve of the launch of the company’s SES 9 communications craft aboard a Falcon 9 rocket.

The launch will be the first human spaceflight mission to a polar orbit. Liftoff is set for Monday, March 31, at 9:46 p.m. EDT (0146 UTC).
