NASA and Russia’s Federal Space Agency are negotiating for the US International Space Station (ISS) segments to supply power to the planned Russian Multipurpose Laboratory Module (MLM). With only 18 Space Shuttle flights remaining Japan’s Centrifuge Accommodation Module and Russia’s Science Power Platform, which would have powered the MLM, will have to be dropped from the ISS configuration. The MLM will be launched by a Russian Proton rocket at the end of 2007.
