A Northrop Grumman Cygnus XL cargo ship, launched Sunday by SpaceX, experienced a main engine failure preventing its scheduled Wednesday docking at the International Space Station. The capsule, carrying over 11,000 pounds of supplies including food, science experiments, and spare parts, is now delayed. NASA is evaluating alternative plans while the Cygnus capsule remains in orbit. This was the debut flight of the larger Cygnus XL model.
