SpaceX engineers are readying two Falcon 9 rockets for launches Oct. 7 and Oct. 9 from Florida and California, setting up another quick turnaround to first deploy a large TV broadcasting satellite for SES and EchoStar over the United States with a previously-flown booster, then add 10 more spacecraft to Iridium’s fleet of new-generation voice and data relay network.

This is the third and final launch that Amazon booked onboard a SpaceX Falcon 9 rocket. Liftoff from pad 40 at Cape Canaveral Space Force Station is scheduled for no earlier than Oct. 12 at 8:29 p.m. EDT (0029 UTC).

Data from the Jan. 19 in-flight launch escape demonstration of SpaceX’s Crew Dragon spacecraft indicate the performance of the capsule’s SuperDraco abort engines was “flawless” as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about 3.3Gs, officials said Thursday.
