Live coverage: SpaceX supply ship returns to Earth

The Starlink 15-9 mission will be the 200th orbital launch from Space Launch Complex 4 East to date. SpaceX is targeting liftoff of its Falcon 9 rocket at 8:36 p.m. PDT (11:36 p.m. EDT, 0336 UTC).

The maiden flight of NASA’s Space Launch System, a heavy-lift human-rated rocket and one of the agency’s core programs, will likely not be ready for takeoff until 2020, officials said recently.

Two Falcon 9 rockets with reused first stage boosters will place the initial block of DigitalGlobe’s commercial WorldView Legion satellite fleet in orbit in 2021, the Earth-imaging company recently announced.
