SANTA BARBARA, CA - OCTOBER 07: The SpaceX Falcon 9 rocket (R) separates from the space craft (L) behind the rocket trail after launching from Vandenberg Air Force Base carrying the SAOCOM 1A and ITASAT 1 satellites, as seen on October 7, 2018 near Santa Barbara, California. After launching the satellites, the Falcon 9 rocket successfully returned to land on solid ground near the launch site rather than at sea. The satellites will become part of a six-satellite constellation that will work in tandem with an Italian constellation known as COSMO-SkyMed. (Photo by David McNew/Getty Images)
