Q&A with Jeff Bezos, founder of Blue Origin

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.

With a thundering, sky-lighting predawn blastoff from Cape Canaveral, a Falcon 9 rocket fired into orbit early Saturday with a Dragon cargo capsule in pursuit of the International Space Station. Minutes later, the rocket’s first stage booster fell from the sky and executed a pinpoint propulsive landing just offshore, setting the stage for another resupply mission for NASA this summer using the same vehicle.

Cocooned inside the nose cone of its Falcon 9 rocket booster, the U.S. Air Force’s X-37B spaceplane journeyed from a former space shuttle hangar at NASA’s Kennedy Space Center, past the Vehicle Assembly Building and toward launch pad 39A last week ahead of liftoff Thursday.
