Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX has many pads, on the East Coast of the US they own SLC-40 at Cape Canaveral and LC-39A at the Kennedy Space Center for their lower inclination launches. They also own SLC-4E at Vandenberg, California for their high inclination launches. Another site is also being developed at Boca Chica, Texas.
Second operational Starlink payload of 2020 and third overall. The Falcon 9 launch vehicle will carry a batch of 60 Starlink satellites that will be insterted in a Low Earth Orbit (LEO) at an altitude of 290 km (180 mi) and an inclination of 53Â°. They will then split into three orbital planes and raise their orbits to reach an operational altitude of 550 km (342 mi). The Starlink LEO constellation aims to provide worldwide affordable satellite internet access. 182 satellites (120 operational) have been deployed so far, the goal scheduled for the mid-2020s being 12,000 satellites in orbit, with a possible later extension to 42,000. The booster for this launch will be B1051, a Block 5 generation core which previously flew on SpaceX's Demonstration Mission 1 (first Crew Dragon test flight) and launched the Canadian Space Agency's RADARSAT Constellation.
