Russian Soyuz spacecraft to get new Kurs-NA ISS docking system in 2015

Russian spacecraft performing flights to the International Space Station will be equipped with a new automated approach and docking system starting next year, the manufacturer of the system said Monday, RIA Novosti reports.

"All Kurs systems will be replaced with Kurs-NA equipment in 2015," the Izhevskiy Radiozavod company said in a statement.

The unmanned Progress M-21M resupply vehicle currently docked with the station successfully tested the new system last week.

The cargo ship undocked from the ISS in an automatic mode using the new Kurs-NA system on Wednesday and re-docked Friday.

The Kurs-NA system boasts advanced electronics, a fully-digitized control system and increased docking precision compared to its predecessor.

The improved system will be used on all upgraded Progress and manned Soyuz spacecraft in the future.

The Kurs-NA was first tested in space in July 2012, but the Progress cargo ship in that test failed to re-dock with the station due to an apparent failure in the system's sensors.

During a second test in November, the Progress M-21M resupply craft was forced to dock in a manual mode due to another failure of the Kurs-NA system.

An unmanned Russian cargo ship parked itself at the International Space Station tonight (July 28), in a second attempt to test an updated space docking system, NASA says.

The robotic Russian Progress 47 spacecraft re-docked to the space station to test the new Kurs-NA docking system.

The automated cargo ship safely approached the station and automatically attached itself to the Pirs docking compartment on the Russian segment of the massive orbiting laboratory at 9:01 p.m. EDT (0101 GMT July 29).

Russia intends to use the Kurs-NA docking system on future unmanned Progress spacecraft and manned Soyuz vehicles.

The Progress' safe docking followed a failed first attempt four days ago, on July 23, which was aborted after a technical glitch prevented the spacecraft from reaching the orbiting outpost.

After that attempt, the Progress 47's onboard computers kept the craft a safe distance away from the station while Russian engineers analyzed the failure.
