Cargo Ship Reaches Space Station

HOUSTON, July 4 (UPI) — An unmanned cargo spacecraft docked with the International Space Station Sunday, two days later after its initial attempt failed, NASA said.

The ISS Progress 38 hooked to the aft end of the space station’s Zvezda service module “flawlessly” using an automated system at 12:17 p.m. EDT Sunday, NASA said on its Web site.

The space drone brought 1,918 pounds of propellant, 110 pounds of oxygen, 220 pounds of water and 2,667 pounds of experiment equipment, spare parts and other supplies to the space station circling the Earth.

Progress was launched June 30 from the Baikonur Cosmodrome in Kazakhstan. An attempted docking Friday was called off when telemetry between the cargo spacecraft and the space station was lost about 25 minutes before its planned docking.

NASA said the aborted docking was likely caused by the activation of a TV transmitter, which created interference that broke up the command link between Progress and the International Space Station. That system was not activated for Sunday’s docking.

The TORU TV system is supposed to provide a view of Zvezda’s docking target to station Commander Alexander Skvorstov, if he had to operate a joystick to dock Progress manually, NASA said.
