Time-lapse video: The Falcon Heavy goes vertical again

SpaceX’s launch team loaded super-chilled liquid propellants into a two-stage Falcon 9 rocket Wednesday and fired the booster’s nine first stage engines at Cape Canaveral, marching toward liftoff Monday with a NASA observatory built to find planets around other stars in our galactic neighborhood.

SpaceX’s Falcon 9 rocket completed a prelaunch hotfire test at launch pad 39A at NASA’s Kennedy Space Center in Florida on Tuesday in a signifiant step before Sunday’s scheduled liftoff of a top secret U.S. government spy payload.

The Starlink 10-59 mission added 28 broadband internet satellites into the growing megaconstellation. SpaceX completed liftoff from pad 40 at Cape Canaveral Space Force Station at 2:46 a.m. EDT (0646 UTC).
