Falcon 9 / TESS launch replays

A modified version of Russia’s Soyuz rocket launched Friday from the Plesetsk Cosmodrome, a spaceport on the edge of the Russian Arctic, with a military satellite whose mission is shrouded in mystery.

Final preparations began this weekend at NASA’s Stennis Space Center in Mississippi to load super-cold liquid hydrogen and liquid oxygen into the massive core stage of the Space Launch System heavy-lift rocket for the first time as soon as Monday.

The launch of SpaceX’s Falcon 9 rocket occurred less than three hours after the planned Falcon Heavy launch. Liftoff of the Starlink 6-36 mission happened at 11:01 p.m. EST (0401 UTC).
