This will mark the first time SpaceX has attempted a ground landing of the Falcon 9 on the West Coast.
After launching a satellite from California's Vandenberg Air Force Base on Sunday evening with the Falcon 9 rocket, the spaceflight company brought its first stage booster back to Earth just under eight minutes after liftoff.
Local residents may see the first stage of the Falcon 9 returning to Vandenberg AFB, including multiple engine burns associated with the landing.

The satellite is the first of two for Argentina's space agency, Comision Nacional de Actividades Espaciales, and will work in conjunction with a constellation of Italian space agency satellites. The retro firings slowed the rocket down from supersonic speeds, setting off a sonic boom that could be heard in some areas (but not others). "Sonic booms generate a sound similar to an explosion or a clap of thunder".
The Air Force said before the 7:22 p.m. launch that it expected that people as far away as Sacramento and Southern California would see the rocket's contrail. Prior landings have taken place on the East Coast. SpaceX founder and CEO Elon Musk warned that the booms "won't be subtle".
The mission could also create a spectacular light show visible across the Southland, depending on weather conditions. Its name is short for Satelite Argentino de Observacion Con Microondas.
Later, SpaceX reported that the SAOCOM 1A radar satellite was placed in its proper pole-to-pole orbit.
