Last week the russian cosmonauts onboard the ISS did some repairs on the Soyuz Spacecraft removing some bolts which were feared to have been the cause for the last 2 bad landings of the Soyuz spacecraft. They used the Orlan space suit and the Pirs docking compartment.
Is there a special rule that Orlan suits will be used if work is done on the russian part, while the US suit will be used on EVAs using the quest airlock, or can the Orlan also be used in the Quest airlock?
Which spacesuit is better? How are the differences between those two suits?
