The space station astronauts have entered the Dragon, the world's first commercial supply ship. Early Saturday, crew of the International Space Station slid open the hatch of its new addition, the SpaceX capsule named Dragon, which made history with its arrival Friday. NASA astronaut Donald Pettit was the first one in. He said it smelled like a brand new car and reminded him of the cargo capability of his pickup truck. Pettit and his crewmates have until the middle of next week to unload Dragon's groceries and refill the capsule with gear for return to Earth. The California-based SpaceX is the first private company to send a vessel to the space station. NASA is turning over delivery work so it can focus on getting astronauts to asteroids and Mars, according to a report of the Associated Press.
