Photos: Atlas 5 rocket aims for International Space Station

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.

Returning to service after a six-year hiatus, Orbital ATK’s revamped Minotaur-C rocket soared into space Tuesday from California’s Central Coast with 10 commercial Earth-imaging spacecraft for Planet, a San Francisco-based company with a globe-spanning satellite fleet mapping the world’s land masses every day.

Bidding farewell to the International Space Station today, the commercial Cygnus cargo ship separated to a safe distance before igniting an intentional fire in microgravity like never before, all in the name of science.
