Arizonans, and presumably Americans all over the country were collectively confused and maybe a little scared when a giant light appeared in the sky on Sunday night.
Falcon 9 launched from Space Launch Complex 4E (SLC-4E), located at the Vandenberg Air Force Base off the coast of northwest Los Angeles in California, on Sunday October 7th at 7:21 p.m.
Still, Vandenberg Air Force Base had warned residents last week in nearby Lompoc and other Central California cities that they could hear "one or more" sonic booms associated with the landing of the first-stage booster.
The event marked the company's first West Coast landing on dry land.
Booms from the Falcon 9 booster's re-entry into the atmosphere were predicted to shake the Pacific Coast as far southeast as Ventura County, but officials said the noise pattern can not be accurately predicted given varying upper-atmospheric weather patterns.
SpaceX used the same first stage for the Saocom-1A mission that launched 10 satellites for Iridium about 10-and-a-half weeks ago, also from Vandenberg.More news: Former Trump Aide Hope Hicks Lands Job as Communications Director for Fox
Thanks to the low-energy orbit, relatively small satellite, and Falcon 9 Block 5's healthy performance margins, B1048 likely experienced the most forgiving recovery conditions since SpaceX began landing and reusing boosters, making the rocket a prime candidate to be the first SpaceX Falcon 9 booster to fly three times.
By the way: SpaceX would like to land every booster on terra firma, to ease the reflight process. Prior landings have taken place on the East Coast.
Argentina's satellite will reportedly track natural disasters, crop yields and soil-moisture levels from 385 miles (620km) above the earth.
SAOCOM 1B is planned to launch next year.
SAOCOM 1, together with the Italian COSMO-SkyMed X-Band SAR constellation, make up the Italian-Argentine Satellite System for Emergency Management, or SIASGE. Its acronym is short for Satelite Argentino de Observacion Con Microondas.
