SpaceX carried out the first polar orbital satellite launch from the East Coast Cape Canaveral launch facility on Sunday. The Falcon 9 mission carries three payloads, including a synthetic aperture SAOCOM-1B radar satellite operated on behalf of the Argentine Space Agency, and two small satellites for Tyvack and PlanetiQ customers.
The launch took place at 19:18 EDT from Florida and used a prime booster that SpaceX has previously flown on two separate commercial supply missions on behalf of NASA for the International Space Station, as well as one of the recent launches of SpaceX̵
Initially, this was supposed to be one of two launches that SpaceX would launch on Sunday – both from the same launch facility, albeit on different pads. This would be a historic first, but the weather earlier in the day meant that the first scheduled mission, the launch of Starlink, had been canceled and would be rescheduled.
After all, SpaceX would like to launch with a cadence that includes multiple launches a day, and that would be a great test of its ability to put that ambition into action. Given how aggressive the company was at launching Starlink, it seems likely that we will encounter another opportunity for a double-start day at some point in the future.
