SAN DIEGO (KGTV) - San Diego residents startled by flashing streaks of light in the sky last year should once again be on the lookout for strange sightings from above.
SpaceX is set to re-launch its Falcon 9 rocket from Vandenberg Air Force Base on Sunday, at around 7:21 p.m. local time, according to an advisory by Air Force officials.
The rocket is the same which drew the attention of San Diegans after its fourth launch back in December.
This time, the Falcon 9 will deliver an Argentinian satellite, SAOCOM 1A, into space before re-entering the atmosphere and landing back at Vandenberg AFB.
It will be the first landing attempt on the ground at Vandenberg, with previous landings occurring on company-owned drone ships.
The $600 million satellite will deliver radar imagery which can help emergency responders of environmental disasters.
Residents along California's Central Coast were warned in an advisory by Air Force officials that they may hear sonic boom's from the re-entry.
Sonic boom's are created by shock waves from objects traveling through the air faster than the speed of sound.
Air Force officials said weather conditions and other factors will play a role in how much residents actually hear.
