An unmanned Russian Progress spacecraft arrived at the international space station July 27 bearing food, supplies and a repair kit for a malfunctioning spacesuit on the orbiting outpost. The robotic Progress 52 space tug docked at the space station’s Earth-facing Pirs port at 10:26 p.m. EDT, after launching from Kazakhstan’s Baikonur Cosmodrome less than six hours earlier. The vehicle lifted off on a Russian Soyuz rocket at 4:45 p.m. EST.

The cargo ship was loaded with nearly 2.7 metric tons of food, fuel, hardware and science experiment equipment for the six-person crew of the station’s Expedition 36 mission. Among its cargo is a set of tools intended to help the astronauts investigate and patch up the spacesuit that malfunctioned during a July 16 spacewalk outside the orbiting laboratory.

That spacewalk was terminated early after just 92 minutes when water began to leak into the helmet of spacewalker Luca Parmitano, an Italian astronaut with the European Space Agency. Parmitano and fellow spacewalker Chris Cassidy of NASA aborted the excursion, which was intended to perform maintenance work to prepare the space station for the arrival of a new Russian module later this year.

“The investigation is ongoing, troubleshooting is ongoing to try to isolate the exact cause of the water intrusion into Luca Parmitano’s helmet,” NASA spokesman Rob Navias said during launch coverage on NASA TV.

Progress 52’s express trip brought it to the space in station in just six hours, docking after only four orbits of the planet — a shorter journey that has been adopted recently to save vehicles time on a trip that used to take multiple days.

The docking came just two days after another Progress resupply vehicle filled with trash and an astronaut treadmill was cast off from the space station to be burned up over the Pacific Ocean as it re-entered Earth’s atmosphere. 

The next space station resupply delivery craft — the H-2 Transfer Vehicle-4 from the Japan Aerospace Exploration Agency — was scheduled at press time to lift off Aug. 3 from Japan’s Tanegashima Space Center. It will ferry 3.2 metric tons of dry cargo, water, experiments and spare parts to the orbiting laboratory, according to NASA.
