On Friday 21 January, held a new vehicular exit outside the international space station. Participated in the exit Skripochka Dmitry Kondratyev and Oleg, who would spend 5 hours and 23 minutes outside the orbiting complex, clad in their spacesuits Orlan-MK. The two astronauts depressurized Pirs module at 14:09 UTC and the hatch opened their twenty minutes later. The activity would be monitored from both Moscow and Houston. NASA gave the Russians a television camera and lights to facilitate tracking from the ground. Scott Kelly and Alexander Kaleri during EVA remain inside their Soyuz spacecraft with the hatch closed, prepared in case there was a accidental depressurization of the station. Cady Coleman and Paolo Nespoli remained for their part in the American segment, with access to the second Soyuz. The first task of the two astronauts outside the ISS was to go to the Zvezda module, which temporarily stopped an antenna, cable and tools, and protective thermal blankets. After the antenna system installed RTSIT (Radio Technical Information System for Transfer), which serve to transmit large data files at speeds up to 100 Mb / s via radio from the Russian segment. They also made appropriate connections. This is complete, removed a generation experiment plasma pulses to study changes in the ionosphere due to the space station, which failed shortly after being activated. It also withdrew the commercial experiment Expose-R, with samples of materials exposed to space conditions. The two experiments were taken to the Pirs module where the astronauts took to pick up a camera docking module Rassvet. During a previous EVA on 26 November, they had difficulties in their installation. This time used a special cutter to remove the insulation that bothered. With the work completed, the two companions went back inside the Pirs and closed the hatch at 19:52 UTC. The next EVA, starring by the same men, will occur if there is no news on February 16 and will include the launching ARISSat-1 satellite. ( Photo: NASA )
