Video: Liftoff of Atlas 5 on space station cargo mission

A classified National Reconnaissance Office satellite mission assigned last month to launch on an Orbital ATK Minotaur 1 rocket will take off from Wallops Island in Virginia by the end of 2018, a U.S. Air Force spokesperson confirmed Wednesday.

Astra’s privately-developed small satellite launcher crashed shortly after liftoff from Alaska Friday evening on the company’s first try at reaching orbit.

NASA has narrowed its choices for a new billion-dollar robotic space mission: A plutonium-powered quadcopter to explore the hazy landscape of Saturn’s largest moon Titan, or a probe to scoop up a piece of a comet and return it to Earth.
