The ISS Progress 33 cargo craft’s rendezvous with the station Sunday was successful. The Progress had undocked from the Pirs docking compartment June 30 and performed a retrograde burn placing the spacecraft into a parking orbit. Another burn on Saturday set up the Progress for its final rendezvous with the station on Sunday. The supply ship approached the Zvezda service module to test new automated rendezvous equipment mounted on Zvezda during a pair of spacewalks in June.

This equipment will be used to guide the new Mini-Research Module-2 (MRM2) to an unpiloted docking to the zenith port of Zvezda later this year. MRM2 will serve as a new docking port for Russian spacecraft and an additional airlock for spacewalks conducted out of the Russian segment.Meanwhile, the launch of space shuttle Endeavour and the STS-127 crew is set for 6:51 p.m. EDT Monday. Officials at NASA’s Kennedy Space Center in Florida called off Sunday’s liftoff due to inclement weather.

In other station news, one of the station’s eight beta gimbal assemblies, which help provide the station with solar power, stalled at about 6 p.m. Thursday. Flight controllers weren’t able to clear the stall, and the Fault Detection, Isolation and Recovery (FDIR) system automatically powered the motor off.

Flight controllers and engineers are analyzing the situation and developing a course of action. There is no immediate concern for the health and safety of the crew, and no immediate cause for concern regarding upcoming station events such as the STS-127 mission.

Also, just after 6:30 p.m. EDT Friday, station Commander Gennady Padalka reported seeing visible smoke emanating from the SRV-K, a Russian water processing unit in the Zvezda Service Module. Padalka immediately shut off power to the equipment and the smoke began to quickly dissipate. The smoke was not at a level that required the crew to take any further protective measures onboard, and they did not need to don breathing masks. There is no further impact to the station’s operations.

Similar water processing equipment exists onboard in the U.S. segment of the complex. The smoke did ring alarms on the station and the incident occurred about an hour after the crew had been scheduled to begin their sleep period, although crew members apparently were still awake at the time. Russian flight contollers are analyzing data from the problem, but there is no impact to the crew’s normal activities.
