One of the larger jobs planned is cleaning up the Permanent Multipurpose Module (PMM). The Space Shuttle brought this module to the ISS, the module is better known by the name Leonardo. Leonardo used to return to Earth. In total it has been launched eight times. The last time, on the 24^th of February 2011, it became a permanent part of the ISS. You could call it our storage attic. It is very untidy. Both old and new equipment is stored there. We have to catalogue everything in the module in cooperation with ground control. I found tanks that can convert hydrogen to water, pumps, many spare parts and packaging material, food, waste and a whole lot more. It is like buying a new house and finding the previous owner’s possessions in the attic. It is always surprising what you find. (more...)
