SFI LIVE: SpaceX launching Inmarsat-5 F4 communications satellite

KENNEDY SPACE CENTER, Fla. — Hawthorne, California-based SpaceX has an expendable Falcon 9 rocket ready to launch the Inmarsat-5 Flight 4 communications satellite to a geostationary transfer orbit. Tune in here for our live webcast from KSC!

Taking flight from Launch Complex 39A, the mission has a 49-minute window that opens at 7:21 p.m. EDT (23:21 GMT) to get off the pad. Because the satellite is more than 13,000 pounds (5,900 kilograms), the satellite is too heavy to allow for a first stage recovery attempt.

Be sure to tune into SFI LIVE at about 6:50 p.m. EDT (22:50 GMT) for coverage of the mission. Additionally, you can visit SFI’s Mission Monitor page for live updates.
