Booster Recovery

SpaceX operates 2 autonomous spaceport droneships (ASDS) to land their Falcon 9 family of boosters at sea. Droneship landings are required for missions where the booster is not able to carry enough fuel to return to the launch site (RTLS) after delivering a payload into orbit. SpaceX currently has three droneships in operation and another that was retired in 2015.

Of Course I Still Love You

Of Course I Still Love You (OCISLY) is the ASDS used for landings in the Atlantic Ocean. Home-ported at Port Canaveral, Florida, OCISLY has been in service since 2015 and has been used for over 35 landing attempts. 

Status: In service on the US West Coast.

The original droneship, with the same name as one of the current east coast droneships, was used for a number of experimental landing attempts throughout 2015. This droneship was replaced by Of Course I Still Love You which was built on a significantly newer barge and featured a number of upgrades.

Status: Retired.
