Video: Delta 4 launch highlights

The Falcon 9 booster for SpaceX’s next mission fired up briefly on a Cape Canaveral launch pad Sunday in a routine pre-flight test before a scheduled launch Friday night to kick off the final flight of the first version of the company’s Dragon cargo capsule to the International Space Station.

Weeks after leaving its factory in New Orleans, the core stage for NASA’s first Space Launch System flight has been raised into a test stand at the Stennis Space Center to begin a series of checkouts culminating in an eight-minute engine-firing later this year.

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.
