SpaceX Tuesday launched a shipment of groceries to the International Space Station (ISS). The unmanned rocket blasted off from Cape Canaveral, Florida. The ISS was soaring above Australia at liftoff time. Dragon, the SpaceX supply ship, holds more than 1,814 kilograms of food, experiments, and equipment for the six ISS astronauts. The delivery should arrive Friday. SpaceX for the third time will attempt to transform the rocket business by landing a leftover booster on an ocean platform.
