Video: Delta 4 launch highlights

The next Delta 4-Heavy rocket was raised vertical Friday at Cape Canaveral, signaling the start of a comprehensive series of pre-flight tests before liftoff next year with a top secret U.S. government spy satellite.

Now in an elliptical orbit around the sun, the Tesla Roadster launched atop a SpaceX Falcon Heavy rocket Tuesday during the powerful booster’s maiden flight was expected to pass beyond the moon’s orbit overnight Wednesday and reach the orbit of Mars in July as it puts Earth in its rear view mirror, analysts said.

The launch of the next crew to China’s Tiangong space station late Monday (U.S. time) added three astronauts to the population of humans in space, which reached a record number of 17 people in orbit — six Chinese citizens, five Americans, three Russians, two Saudis, and one Emirati astronaut.
