January 14, 2015 in the US segment of the ISS occurred harmful emissions from the cooling system into the atmosphere station. Segment was isolated, the crew is safe in the Russian part of the station. The concentration of pollutants in the atmosphere of the Russian segment of the ISS is within acceptable values. After a while the pressure in the cooling system malfunction has been removed.
12 December 2013 on the ISS stopped working one of the valves inside the 350-pound pump module cooling circuit A. As a result, contour partially out of order, and experts had turn off the part of the auxiliary systems of the American segment of the ISS. To remove the pump and replace it with a reserve, the astronauts performed two spacewalks. December 24 all the work was completed.
May 10, 2013 it was announced that the US segment of the station there was a leak of ammonia from the ISS thermal control system.
The American astronauts carried out unscheduled spacewalk and after five and a half hours to successfully replace the coolant pump.
On the night of August 1, 2010 in the US segment of the ISS tripped breaker cooling system, but later it was possible to include. However, the device was turned off again when you run the coolant pump. August 7 astronauts began to replace the unit, but during the undocking of the last of the four hydraulic connectors leaked ammonia, resulting in the withdrawal operations unit have been suspended. For the completion of the installation of a new pump system thermoregulation American segment of the ISS took three spacewalk.
May 1, 2010 there was an emergency situation during the docking of the cargo ship “Progress M-05M” with the ISS. The docking was performed manually Russian cosmonaut Oleg Kotov due to a system failure “rate”.
October 30, 2007 on one of the solar panels of the ISS revealed damage to deploy one of the two solar panels segment P6, which was set at a constant position during spacewalks. Nov. 3 during spacewalks, astronauts have completed work on the broken pieces of the bonding, the panel itself has been successfully deployed.
August 12, 2007 it was reported that during the spacewalk American astronauts to the ISS Unsubscribe Home command and control computer of the American segment of the station. When this was immediately put into operation the backup computer, and another was transferred from the standby mode dubbing action computer, performing the functions of control. Threat to the life and health of astronauts station was not.
June 13, 2007 on the computer equipment of the Russian segment of the ISS, a number of failures, which caused a false fire alarm at the station. Computers Russian segment, were responsible for the ISS spare navigation system and for providing oxygen station, had to temporarily disable the software from the ISS. Functions have been assigned to the equipment of the shuttle “Atlantis”. The cause of failure in computers of the Russian segment of the ISS became the so-called noise in electricity (static electricity). Specialists of the Russian Mission Control Center in conjunction with the ISS crew was able to restore the computers of the Russian segment of the disaster.
February 11, 2007 in the US segment of the ISS occurred single failure in the power supply system gyrodyne number 2, as well as the communication system. Gyrodyne was stopped, breaks were observed in connection with the US segment. This failure did not result in a loss of orientation of the station and the disruption of the Russian segment of the ISS. Gyrodyne responsible for maintaining the orientation of the ISS in space, was restarted on February 12.
October 26, 2006, after joining the transport ship “Progress M-58″ and the ISS, the space truck could not be fastened firmly to the International Space station. It was assumed that the gap formed due to uncomplicated antenna system rendezvous and docking “Course” is set to “progress”. Experts have decided to take the “Progress” from the ISS on the mooring boom length of 40 inches and hold retry the contraction of “Progress” with the ISS. The operation completed successfully.
September 17, 2006, after separating from the ISS space shuttle “Atlantis” has failed oxygen regeneration system “Electron”. This occurred when restarting the system. The crew felt an unpleasant smell and immediately turn off the “Elektron”. Before the end of the repair of the supplies of oxygen at the station to recharge by pressurization of the oxygen tanks of the ship “Progress”, as well as periodic burning of solid oxygen checkers.
April 25, 2001 have failed all three onboard computer of the American segment of the station, Communication with the Mission Control Center in Houston. Were stopped all work with the Canadian robotic arm Canadarm-2. The accident did not affect the central computer of the Russian segment of the station, so the preparation for the start of the Russian manned spacecraft “Soyuz TM-32″ lasted in the normal manner. As it turned out, there was a breakdown in the storage device, which had been damaged files on your hard disks.
