The European Robotic Arm is already in position to carry science airlock from Rassvet to Nauka, once spacewalkers open its locks...
RS EVA-57 (PET: 0:45; EDT: 4:45pm): The cosmonauts have reached the experiment airlock on the Rassvet module; they must disconnect electrical cables, move insulation and release launch locks before Fedeayev, operating the European robot arm, can move it to the Nauka lab module
ERA connects to the airlock via a special adapter installed during the previous spacewalk:
RS EVA-57 (PET: 1:40; EDT: 5:40pm): Prokopyev and Petelin have completed removal of a protective blanket and disconnected electrical cables linking the experiment airlock with the Rassvet module; they're now releasing the launch locks holding the airlock in place
Cosmonauts now opening the final lock connecting the airlock to Rassvet, before the 150-kilogram device would be moved by the European Robotic Arm to the Nauka module:
RS EVA-57 (PET: 2:06; EDT: 6:06pm): With a final launch lock released, Fedyaev, operating the European Robot Arm from inside the ISS, is ready to move the disconnected experiment airlock from Rassvet to Nauka after inspections to make sure it's free of any obstructions
Another night shift for the #EuropeanRoboticArm (ERA). Tonight's task involves moving an experiment airlock from the Rassvet to the Nauka module on the International @Space_Station. ERA is on the move, operated by an astronaut inside the station.
