An unpiloted Russian cargo craft with about 2.3 tons of supplies and equipment aboard docked Wednesday with the International Space Station. The ISS Progress 17 spacecraft docked at 3:10 p.m. EST to the aft port of the Station’s Zvezda Service Module. The docking, controlled by the automated Kurs docking system, was problem-free. The Station’s Flight Engineer Salizhan Sharipov, assisted by Commander Leroy Chiao, was ready to assume manual control of the docking had it been necessary.
