SANTA BARBARA COUNTY (KRON) – If you’re in Southern California Sunday night — be warned!
You can expect a large sonic boom a little after 7:20 p.m. as SpaceX launches a Falcon 9 rocket from Vandenberg Air Force Base, then attempts its first-ever landing on the West Coast, according to company and military officials.
In an advisory sent to residents in Santa Barbara, Ventura, and San Luis Obispo Counties, Vanderberg Air Force base officials say the rocket will carry the Argentinian SOACOM 1A radar mapping satellite.
“A sonic boom is the sound associated with the shock waves from an aircraft or vehicle traveling faster than the speed of sound. Sonic booms generate a sound similar to an explosion or a clap of thunder,” according to the advisory.
SpaceX Ceo Elon Musk tweeted Californians of the warning on Saturday, saying “Sonic boom warning. This won’t be subtle.”
Officials say the loudness of the boom depends on the weather and other conditions. This will be SpaceX’s first time trying to land a reusable rocket on the West Coast.
