The reusable booster assembly makes the use of rockets more affordable for a wide range of customers across the globe.
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. Eastern during an instantaneous launch window.
The mission launched Argentina's newest Earth-observing satellite, SAOCOMM-1A, which will be used to track natural disasters like floods, wildfires, and oil spills from a low-earth orbit of 385 miles (620km). The company views ground-based rocket landings as better for expediting reuse, since drone ship landings require time to return to port.
If anything goes wrong during the launch and landing, there is a risk of explosion.
SpaceX was also aiming to land its Falcon 9 rocket after successful deployment of the satellite. Pacific time. The launch was delayed one day for "pre-flight vehicle checkouts", SpaceX tweeted last week.
Saocom-1A has an L-band payload created to study soil moisture for agriculture, disaster monitoring and scientific research.
"SAOCOM-1, together with the Italian COSMO-SkyMed X-Band SAR constellation, comprise the Italian-Argentine Satellite System for Emergency Management (SIASGE), a partnership between CONAE and the Italian Space Agency (ASI)", SpaceX officials wrote in a mission description. SpaceX's landing record now stands at 30 successful booster recoveries, 11 at Cape Canaveral, one at Vandenberg and 18 on droneships.
The satellite's twin, SAOCOM-1B, will also launch on a Falcon 9; its liftoff is targeted for next year.
Those who knew they were watching a satellite launch posted videos they captured of the stunning spectacle, including one taken over the downtown Los Angeles skyline and a timelapse from Kern County.
