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

SpaceX surpassed more than 4,000 Starlink internet satellites in orbit with the launch of a Falcon 9 rocket and another batch of 56 spacecraft Thursday from Cape Canaveral, the company’s fourth mission in less than a week.

The launch from pad 40 at Cape Canaveral Space Force Station was delayed a day due to poor weather in the booster landing zone. Liftoff happened at Thursday, Sept. 5, at 11:33 a.m. EDT (1533 UTC).

Astronauts will not fly to the International Space Station on SpaceX’s Crew Dragon spaceship until at least May 2018, NASA said this week, missing a previous target launch date at the end of next year.
