One launch will be at 10:08 am, the second at 7:19 pm. The second launch is the one that will go to a polar orbit from Florida for the first time since 1962. Since 1962, all polar orbital launches have gone from Vandenburg.
Launch time: 1408 GMT (10:08 a.m. EDT)
Launch site: LC-39A, Kennedy Space Center, Florida
A SpaceX Falcon 9 rocket will launch the 12th batch of approximately 60 satellites for SpaceX’s Starlink broadband network, a mission designated Starlink 11. Delayed from Aug. 29. [Aug. 25]
Aug. 30Falcon 9 • SAOCOM 1B
Launch time: 2319 GMT (7:19 p.m. EDT)
Launch site: SLC-40, Cape Canaveral Air Force Station, Florida
A SpaceX Falcon 9 rocket will launch the SAOCOM 1B satellite for CONAE, Argentina’s space agency. SAOCOM 1B is the second of two SAOCOM 1-series Earth observation satellites designed to provide radar imagery to help emergency responders and monitor the environment, including the collection of soil moisture measurements. Delayed from 4th Quarter of 2019, January and February. This mission was originally scheduled to launch from Vandenberg Air Force Base, California. Delayed from March 30 due to coronavirus pandemic. Delayed from Aug. 27 in ripple effect from Delta 4-Heavy/NROL-44 delay. [Aug. 27]
BTW, the reason we have not launched polar orbital missions from Florida since 1962.
On November 30, 1960, a Thor-Able rocket Thor-Ablestar (predecessor of the Delta rocket family) proceeding south on a polar orbital mission exploded, with a piece dropping on Cuba and killing Rufina the Cow. In response, we phased out polar orbital missions from Florida, sending them to Vandenburg instead.
NASA now feels confident enough in Falcon 9 to allow these polar missions to resume from Florida and today’s launch was a critical milestone in that regard.
(Note: It was a Thor-Ablestar, the second stage being an enlarged version of the earlier Able upper stage.)
Cuba sent the recovered pieces of the rocket to China, which is estimated to have saved China at least 2 or 3 years on developing their rocket program.
