SpaceX landed the rocket's first stage at a newly built landing pad called LZ-4 that is located near Vandenberg's SLC-4E launch pad where the rocket took off. The California-based aerospace manufacturing company founded by Elon Musk launched its Falcon 9 rocket Sunday evening. The first stage returned back to the Earth base, landing about 8 minutes after its takeoff. Boosters are shorter-burning rocket motors/engines that are used alongside the main rockets to augment the space vehicle's takeoff thrust and payload capacity during initial stage launch.
This marks the first time that the Falcon 9 has landed anywhere else but Cape Canaveral in Florida or the company's droneship Of Course I Still Love You.
SpaceX said the primary objective of the mission is to place the SAOCOM 1A satellite into orbit. "Flying both constellations along the same orbit supports a rapid response by providing SAR information in emergency situations".
