Drone’s view of Sunday’s SpaceX rocket landing

SpaceX has slowed development of the Falcon Heavy rocket, a mega-booster made of three Falcon 9 booster cores strapped together, as the company recovers from a launch failure last month, delaying the new rocket’s debut until early 2016.

The mission comes as SpaceX is preparing for a week that includes a rideshare flight; a dual-manifest, Moon bound missions; and Starship Flight 7. Liftoff from pad 40 at Cape Canaveral Space Force Station is set for 11:47 a.m. EST (1647 UTC).

Scientists working on a new lightning detection instrument mounted outside the International Space Station said Tuesday they expect little effect on the sensor’s performance from possible contamination from the upper stage of a SpaceX Falcon 9 rocket that launched it into orbit April 2.
