Gallery: Antares rocket explodes

After waiting for a Soyuz crew ferry craft to launch and dock, a commercial Cygnus supply ship arrived at the International Space Station with a fresh delivery of more than 5,100 pounds of provisions and experiments Sunday. The rendezvous culminated in the spaceship’s grapple by the space station’s robotic arm at 7:28 a.m. EDT (1128 GMT).

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.

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a two-day pursuit of the International Space Station.
