SpaceX Prepping for Third Station Run

Will carry food, tools and science experiments on rocket

The International Space Station is about to get another commercial shipment.

The California company known as SpaceX is set to launch its unmanned Falcon rocket on Friday morning, hoisting a Dragon capsule containing more than a ton of food, tools, computer hardware and science experiments.

There won't be any ice cream, though, for the six-man station crew. The freezers going up are filled with mouse stem cells, protein crystals and other research items. On the previous Dragon delivery in October, chocolate-vanilla swirl was tucked inside.
