SpaceX Falcon 9 First Successful Landing

A Falcon 9 first-stage booster is a reusable rocket booster used on the Falcon 9 and Falcon Heavy orbital launch vehicles manufactured by SpaceX.^¹ The manufacture of first-stage booster constitutes about 60% of the launch price of a single expended Falcon 9, which led SpaceX to develop a program dedicated to recovery and reuse of these boosters.^¹ After multiple attempts, some as early as 2010, at controlling the re-entry of the first stage after its separation from the second stage, the first successful controlled landing of a first stage occurred on December 22, 2015, on the first flight of the Full Thrust version.^¹ Since then, Falcon 9 first-stage boosters have been landed and recovered 630 times out of 643 attempts, including synchronized recoveries of the side-boosters of most Falcon Heavy flights.^¹
