Update: The SpaceX Falcon 9 launches with the Intelsat 40e satellite and NASA’s TEMPO instrument at 12:30 a.m. EDT from Cape Canaveral Space Force Station. The first stage of the booster successfully landed on a drone ship stationed in the Atlantic Ocean a short time later.
Tune in live as SpaceX targets at 12:30 a.m. EST on Friday, April 7, for the Falcon 9 launch from Cape Canaveral Space Force Station in Florida.
The Intelsat satellite operator’s mission in Luxembourg will carry the Intelsat satellite 40e on an easterly trajectory from Launch Complex 40. The satellite also hosts a secondary payload, NASA’s Tropospheric Emissions Pollution Monitoring (TEMPO) instrument.
About eight minutes after liftoff, the first supporting stage will target the unmanned SpaceX A Shortfall of Gravitas ship stationed in the Atlantic Ocean for a landing attempt. No local sonic boom is expected this time.
Space Force controllers predicted a 90% chance of favorable weather conditions for takeoff for tonight’s launch attempt.
