Q&A with Elon Musk, SpaceX’s founder and CEO

This mission follows a similar model of processing used during the Rapid Response Trailblazer (RRT-1) mission, which saw the launch of the GPS 3 Space Vehicle 07 (SV-07) spacecraft on a Falcon 9 instead of a United Launch Alliance Vulcan rocket as originally planned.

The core booster from the Falcon Heavy rocket that launched Thursday from NASA’s Kennedy Space Center in Florida tipped over in rough seas after landing on an offshore drone ship, SpaceX officials said Monday.

Overcoming 50-50 weather odds, SpaceX launched a Falcon 9 rocket from Cape Canaveral Thursday morning on its 44th Starlink delivery mission of the year. Liftoff from Space Launch Complex 40 occurred at 1:36 a.m. EDT (0536 UTC), the fourth launch opportunity of the window.
