Mark in the full water survival suit (several layers of warm kit, underneath the rubber dry suit) floating on the Hydrolab pool. If the cosmonauts must evacuate from a capsule into the ocean they will put on this suit if they have time, otherwise they can make an emergency evacuation in their space suits. This water survival suit is designed to keep cosmonauts alive in Arctic water for 24 hours. It's very warm... so much so that getting into it in the confined space of the capsule can kill a cosmonaut from heat exhaustion. |
