Video: Liftoff of Delta 4 with WGS 7

A mysterious space vehicle described by Chinese state media as an experimental reusable spacecraft completed a two-day flight in low Earth orbit Sunday.

Running a day late, a United Launch Alliance heavy-lift Delta 4 rocket thundered away from Cape Canaveral early Sunday, boosting NASA’s $1.5 billion Parker Solar Probe into space on a daring seven-year mission to “touch the sun” with repeated trips through the star’s blazing outer atmosphere.

Perspectives of Friday’s United Launch Alliance Atlas 5 rocket flight were snapped from a commercial airliner, a satellite observer in Australia and the booster itself.
