"Are the ESA and JAXA astronauts expected to be more familiar with the modules from their agencies than the NASA and Russian astronauts would be"<br /><br />Expected? No, but in reality they will. SInce they spend more time in their home country they can get more training. Right now we are trying to evaluate how best to conduct training int he regime of 6 crew members. Clearly each person can't be an expert in all areas but need some familiarity. Fortunately, the USOS (US Lab, Nodes, Columbus, JEM) is all pretty similar in operation.
