Shuttle Atlantis unwrapped ahead of public debut

Watch a time lapse replay of SpaceX’s next Falcon 9 rocket being raised vertical Thursday at launch pad 39A at NASA’s Kennedy Space Center in Florida for a mock countdown and engine test, ahead of a scheduled liftoff this weekend with an Intelsat communications satellite.

A SpaceX Falcon Heavy rocket thundered into the sky over Florida’s Space Coast Sunday night and deployed a sophisticated internet satellite for Viasat into a circular orbit more than 20,000 miles over the equator, delivering for a competitor to SpaceX’s own Starlink broadband network.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Monday, heading due east over the Atlantic Ocean to deliver the Koreasat 5A communications satellite into orbit around 36 minutes later.
