A batch of 24 satellites for the Starlink mega-constellation - SpaceX's project for space-based Internet communication system.
Location
Space Launch Complex 4E
Vandenberg SFB, CA, USA
Find the best place to watch the launch from Vandenberg
Space Launch Complex 4E has witnessed the launch of 212 rockets, including 212 orbital launch attempts. While Vandenberg SFB, CA, USA, has been the site for 826 rocket launches.
Vandenberg Space Force Base is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base, equivalent to an Air Force air base wing. In addition to its military space launch mission, Vandenberg Space Force Base also hosts space launches for civil and commercial space entities, such as NASA and SpaceX.
Rocket
SpaceX Falcon 9 Block 5
Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. The Block 5 variant is the fifth major interval aimed at improving upon the ability for rapid reusability.
Landing
Core B1097
The Falcon 9 first stage B1097 will attempt to land on ASDS OCISLY after its 1st flight. Booster B1097 last launched unknown and has seen 0 successful launches and landings. Falcon 9 booster.
Of Course I Still Love You - OCISLY
The second ASDS barge, Of Course I Still Love You (OCISLY) services launches in the Pacific Ocean and was the site of the first landing of a SpaceX Falcon 9 first stage during CRS-8, the launch of a Dragon spacecraft to the International Space Station.
Autonomous Spaceport Drone Ship - ASDS
An autonomous spaceport drone ship (ASDS) is an ocean-going vessel derived from a deck barge, outfitted with station-keeping engines and a large landing platform. Construction of such ships was commissioned by aerospace company SpaceX to allow for recovery of rocket first-stages at sea for high-velocity missions which do not carry enough fuel to return to the launch site after lofting spacecraft onto an orbital trajectory.
Agency
SpaceX
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 operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
