Launch Pad & Location
Space Launch Complex 4E
Vandenberg SFB, CA, USA
The Space Launch Complex 4E launch pad has hosted 266 rocket launches, including 266 orbital launch attempts. The Vandenberg SFB, CA, USA launch site has been the location for 882 total 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.
SpaceX Falcon 9 Block 5 Rocket
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.
Rocket Booster Landing & Recovery
Core B1082
The Falcon 9 first stage B1082 has landed on ASDS OCISLY after its 20th flight. Reusable booster B1082 last flew on 04/15/2026 and has completed 21 successful launch and landing missions. Falcon 9 Block 5 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.
SpaceX Agency
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.
