The unpiloted Progress 18 cargo ship docked with the International Space Station on Saturday, delivering a fresh batch of supplies. The spacecraft nearly connected automatically to the Zvezda Service Module, but Commander Sergei Krikalev had to take over because of communications problems between ground control and the Progress.ship. It’s loaded up with food, propellant, oxygen, water, spare parts, and experiment hardware. It also brought along the new camera system that will help astronauts inspect the space shuttle for damage when it docks.
