CAPE CANAVERAL, Fla. (AP) – SpaceX has made an early holiday delivery to the International Space Station. The Dragon capsule arrived at the orbiting outpost Sunday, delivering “mighty mice,” pest-killing worms and a smart, empathetic robot. Station commander Luca Parmitano used a large robot arm to capture the Dragon on Sunday. Launched Thursday from Florida, the capsule holds 3 tons of supplies, including extra brawny mice dubbed “mighty mice” for a muscle experiment. There are also 120,000 roundworms, or nematodes of a beneficial variety that are part of an agricultural experiment. Plus there is a large, round robot head with artificial intelligence and Christmas presents.
