Unmanned supply rocket breaks apart

An unmanned SpaceX rocket carrying supplies to the International Space Station broke apart Sunday shortly after liftoff. It was a severe blow to NASA, the third cargo mission to fail in eight months.

The accident happened about 2½ minutes into the flight from Cape Canaveral, Florida.

More than 5,200 pounds of space station cargo were on board, including the first docking port designed for future commercial crew capsules, a new spacesuit and a water filtration system.

NASA officials said they have enough supplies for the three-person crew on board the station to last till October and still plan to send three more crew members up in a late July launch.
