Video: Falcon 9 launch as seen from KSC press site (members only)

SpaceX launched Argentina’s SAOCOM 1B radar observation satellite from Cape Canaveral at 7:18 p.m. EDT (2318 GMT) Sunday. A Falcon 9 rocket headed toward the south on a trajectory hugging the Florida East Coast on the first flight into polar orbit from Cape Canaveral since 1969, and the first stage booster returned to the spaceport for an onshore landing minutes after liftoff.

The U.S. military’s next GPS navigation satellite was ready for launch from Cape Canaveral at 9:43 p.m. EDT Friday (0143 GMT Saturday) aboard a SpaceX Falcon 9 rocket. But SpaceX aborted the countdown just two seconds prior to liftoff.

NASA’s Juno spacecraft must complete a carefully-planned sequence of events as it closes in on Jupiter for a make-or-break orbit insertion burn July 4.
