The approach to the space station was slower than usual because controllers on the ground and astronauts on the International Space Station were carefully monitoring Progress's position, NASA officials said.
At first the Progress was "soft-docked" and not secured in place with hooks in latches, giving the station crew and flight controllers a chance to make sure its stuck antenna posed no risk to the station's exterior. When they saw it was safe, the Progress was slowly drawn into the port and secured.
Progress delivered 1,764 pounds (800 kg) of propellant, 57 pounds (26 kg) of air, 48 pounds (21 kg) of oxygen, 926 pounds (420 kg) of water and 3,348 pounds (1519 kg) of experiment hardware, spare parts and other supplies to the residents of the space station, NASA officials said.
