Video: Antares rocket explodes

An Antares rocket carrying the Cygnus cargo ship has exploded moments after lift off from Wallops Island, Virginia.

Repair crews in Virginia have restored the Antares booster’s launch pad — damaged in an explosive rocket crash nearly one year ago — to flight-ready status as the Orbital ATK launcher moves toward a return-to-flight in 2016.

The year ended with a deluge of big news, reminding us of the risks of spaceflight and the thin margins between success and failure on the final frontier. 2014 was also a year of breakthroughs in the exploration of the solar system and the future of human spaceflight.
