Russian cosmonauts successfully relocate radiator during spacewalk outside ISS.
Two Russian cosmonauts will attempt their third spacewalk tonight to move a radiator and an experiment module from the Rassvet module to the newer Russian Nauka science laboratory on the International Space Station. The work will take four spacewalks in total, with the last two scheduled for April 25 and May 4. The cosmonauts will wear Orlan spacesuits and be assisted by cosmonaut Andrey Fedyaev, who will operate the European Space Agency's robotic arm on Nauka.
