Watch the Falcon 9 launch from pad 39A

One of five CubeSats deployed from the International Space Station last month is testing a steerable drag brake that could find use in future smallsats to return experiment samples to the ground from low Earth orbit, or on low-cost micro-probes to explore other planets.

The last of Japan’s first series of HTV supply ships departed the International Space Station on Tuesday with several tons of trash, old batteries, and unneeded equipment, heading for a destructive re-entry before the debut of an upgraded cargo freighter design.

The mission, dubbed NROL-77, was the final time SpaceX uses Landing Zone 2 to recover a first stage Falcon booster. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 2:16 p.m. EST (1916 UTC).
