Update: Launch of the SpaceX Falcon 9 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 booster successfully landed on a drone ship stationed in the Atlantic Ocean a short time later. Read our full post-launch story here.
Follow live as SpaceX targets 12:30 a.m. EDT Friday, April 7, for the launch of a Falcon 9 rocket from Cape Canaveral Space Force Station in Florida.
The mission for Luxembourg-based satellite operator Intelsat will carry the Intelsat 40e satellite on an easterly trajectory from Launch Complex 40. The satellite also hosts a secondary payload, NASA’s Tropospheric Emissions Monitoring of Pollution instrument (TEMPO).
About eight minutes after liftoff, the first-stage booster will target SpaceX’s A Shortfall of Gravitas drone ship stationed in the Atlantic Ocean for a landing attempt. No local sonic booms are expected this time.
Space Force forecasters have predicted a 90% chance of favorable liftoff weather conditions for tonight’s launch attempt.
