“Are we there yet?” (45th Space Wing's goal of being able to support 48 launches per year from Cape Canaveral)

Polar launch the first since 1969
SpaceX will launch Argentina’s SAOCOM 1B — an Earth observation satellite designed to provide radar imagery — to a polar orbit and will fly a southerly trajectory.
“It’s been decades since that’s been used,” said Schiess†.
The last polar launch from the Cape was in February 1969 — the ESSA-9, also known as TOS-G, a meteorological satellite on a three-stage Delta rocket, a 45th Space Wing spokesman said.
