CAPE CANAVERAL AIR FORCE STATION, Fla. (SpaceX PR) — SpaceX is targeting Wednesday, May 15 for the launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. SpaceX’s Starlink is a next-generation satellite network capable of connecting the globe, especially reaching those who are not yet connected, with reliable and affordable broadband internet services.

The launch window opens at 10:30 p.m. EDT on May 15, or 2:30 UTC on May 16, and closes at 12:00 a.m. on May 16, or 4:00 UTC. A backup launch window opens on Thursday, May 16 at 10:30 p.m. EDT, or 2:30 UTC on May 17, and closes at 12:00 a.m. on May 17, or 4:00 UTC. The Launch webcast will go live about 15 minutes before liftoff at spacex.com/webcast.

Companies Propose Launching 8,700 Satellites into Non-Geosynchronous Orbit

While SpaceX has received most of the attention for its plan to launch more than 4,000 broadband satellite network, the constellation makes up just over half the number of spacecraft that companies have proposed placing in non-geosynchronous satellite orbit (NGSO).

Companies have filed applications with the Federal Communications Commission (FCC) to launch 8,731 NGSO communications satellites. While most of the constellations would provide broadband and communications services, others would collect Earth observation data.

According to the International Telecommunications Union, NGSO spacecraft “occupy a range of orbital positions (LEO satellites are located between 700km-1,500km from the Earth, MEO satellites are located at 10,000km from the Earth), and do not maintain a stationary position, but instead move in relation to the Earth’s surface.”

SpaceX leads the pack with 4,425 spacecraft, followed by Boeing with 2,956 and WorldVu (aka, OneWeb) with 720. Boeing has a second application before the FCC for a constellation with 60 satellites.

The table below provides a summary of the applications filed with the FCC.

SpaceX has filed an application with the Federal Communications Commission (FCC) for approval to launch a satellite constellation composed of 4,425 satellites to provide global broadband and communications services.

The satellites, which will weight 386 kg apiece, will fly in orbits from 1,110 km to 1,325 km and provide services in the Ku and Ka frequency bands.

Key excerpts from the application follow.

Application Excerpts

Space Exploration Holdings, LLC seeks operating authority (i.e., approval for orbital deployment and a station license) for a non-geostationary orbit satellite system in the Fixed-Satellite Service using the Ku and Ka frequency bands.
