A Progress freighter was manually docked with ISS today when its automatic docking system suffered a malfunction 200 feet from the station.

A Progress freighter was manually docked with ISS today when its automatic docking system suffered a malfunction 200 feet from the station.

This freighter was using a new rendezvous radar system, and had spent two extra days approaching the station to do rendezvous tests. What failed has not yet been released.

A Progress freighter, launched yesterday, will not dock with ISS for four days in order to test upgrades to its rendezvou radar system.

Unlike recent Progress vehicles that used the 2AO-VKA and AKR-VKA antennas of Kurs-A system, M-21M is sporting a AO-753A antenna of the Kurs-NA system instead. Once the Progress reaches its preliminary orbit, it will conduct a series of automated engine burns to put it on track to fly within one mile of the station on Wednesday, allowing for the test of the lighter, more-efficient Kurs automated rendezvous system hardware for upgraded Soyuz and Progress vehicles.

After it finishes its flyby, the Progress will loop above and behind the station, returning Friday for a docking.

The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

The damage, caused by the undeployed Progress antenna, appears to have involved a navigational aid needed for ATV-4 … the Laser Radar Reflector (LRR) target. The LRR is needed for the automatic docking of the European ATV during the last part of the rendezvous operations. If the damage is confirmed, the device, recently replaced during an EVA by the Russian crew due to contamination of the optical section, will need to be replaced again. In this event, the European cargo ship could potentially be delayed for several months. ATV-4, named Albert Einstein, has been already delayed from April to June because of a glitch in an avionics box.

A test redocking of a new automatic docking system on a Russian Progress freighter was aborted last night when the system did not work as planned.

They will probably try again on the weekend, after a Japanese cargo craft is berthed with the station.
