On August 30th at 7:18pm SpaceX launched an Earth-observation satellite for Argentina along with two rideshare satellites, GNOMES-1 and Tyvak-0172.
This mission is historic because it demonstrated the capability to launch polar orbit missions from Florida. Polar orbit missions usually launch from the West Coast because of risk of damage to Cuba. The last mission in 1969 resulted in killing a cow in Cuba caused by falling launch debris. SpaceX was cleared to fly because its Falcon 9 rocket is equipped with an automated flight termination system.
