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.
Derek Richardson has a degree in mass media, with an emphasis in contemporary journalism, from Washburn University in Topeka, Kansas. While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor.
