An unmanned Falcon 9 rocket blasts off from Cape Canaveral Air Force Station to deliver equipment and supplies for science experiments to the International Space Station.<br/> <br />Ten minutes later the Dragon cargo capsule on top of the rocket was released. It's the beginning of a two day journey to the space station.<br/> <br />On board are 20 live mice -- the first mammals to fly aboard the Dragon, as part of a new rodent research program on ISS.<br/> <br />There's also what will be the first 3-D printer in space; and an instrument to improve hurricane forecasts.<br/> <br />The mission was delayed one day because of poor weather.
