Northrop Grumman's Cygnus XL cargo ship, launched Sunday, experienced two premature engine shutdowns during its planned rendezvous with the International Space Station. The ship, carrying over 11,000 pounds of supplies, was unable to reach the station on Wednesday as scheduled. The cause of the engine failures is under investigation, and a new arrival time is pending. This is the maiden voyage of the upgraded, larger Cygnus XL, which is designed for increased cargo capacity.
