On October 28, 2014, the Orbital ATK Antares rocket launched from NASA's Wallops Flight Facility in Virginia and exploded almost immediately after leaving the ground because of a "catastrophic anomaly." The explosion destroyed both the rocket and the attached unmanned Cygnus spacecraft, which was carrying 5000 pounds of food, supplies, and experiments to the International Space Station. Now a year later, NASA has uploaded photos of that unfortunate and costly event to its NASA HQ PHOTO Flickr account.

In April 2015, Orbital ATK Executive Vice President Ronald Grabe issued a statement that suggested that the cause of the explosion was "excessive wear in the bearings of a turbo pump" for one of the engines from Aerojet Rocketdyne, a claim that the manufacturer's parent company GenCorp said was "inaccurate and could be misleading," because there was "foreign object debris" in the engine that caused the wear in the bearings.
