Informing about the mission, SpaceX official post added, "This mission marked the second reflight of a Falcon 9 first stage, having previously supported the Iridium-1 mission from Vandenberg Air Force Base in January of this year".
Then on Sunday SpaceX launched Falcon 9 again, this time with 10 low-Earth orbit satellites for the communications company Iridium. A second batch of new satellites for Iridium Communications was sent on board the SpaceX Falcon 9 rocket. Check out the interactive map below for the best spots. "Launch at 1:25 delivering 10 satellites for Iridium". Desch said he's open to the possibility of launching on already-flown Falcon 9s, if the reused rockets can speed up the schedule.
One is the satellite carrier SpaceX designed specifically for the Iridium NEXT missions, which functions something like an orbital PEZ dispenser, popping out each satellite at the correct time so that they fly in the right place.
Instead of simply discarding rockets after one use, by bringing them back home, Musk hopes to refurbish and reuse them to save money on re-flights. That satellite will provide broadcast and communications service throughout eastern Europe. After takeoff, SpaceX will try to land the Falcon 9's first stage - the 14-story high core of the rocket that contains the main engines and most of the fuel - on an autonomous drone ship in the Pacific Ocean.
SpaceX is set to jettison a Bulgarian satellite into orbit onboard its only second-ever recycled delivery rocket.
So far, SpaceX has safely landed first-stage rockets on land or a droneship 13 times.
The 12:10 p.m. PDT BulgariaSat1 liftoff from Cape Canaveral's Kennedy Space Center Launch Complex 39-A took to clear skies without a hitch and was outside Earth's atmosphere within five minutes.
The last time USA rockets launched such simultaneous types of rockets in two days apart was in 1995 when both Lockheed Martin Atlas and Atlas-E sent two separate missions into space with the intention of delivering Intelsat broadcast and Air Force weather satellites to space.
That being said, it could still be refined even more.
