Orlan Vs US Space Suits

Mon Jul 14, 2008 12:37 pm

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?

Orlan can be used at the Quest airlock, but NASA's suits won't fit through Pirs' hatch. Generally, working on the Russian side uses Pirs, work on the western side uses Quest.

The US suit comes in two halves (torso and legs) is generally more customizable to different sizes as a result, which helped with the Shuttle's much more diverse crews. The Russian suit is one-piece and you climb in throught the back.

The new suits NASA is planning for Orion will be more like the Russian suit... climb in through the back. This might be a case where the US/Russian teaming for ISS will result in a "best of both worlds" technology.

IIRC you can get into a Russian suit on your own, whereas somebody must help the astronaut with the US suit.

Apart from that, the Russians use normal breathing air vs. pure oxygen for the Americans.
Exceptions confirm the rule.
