Authentic Space Hardware: ORLAN M SPACE SUIT ![]() It became easier and more mobile. Since 1971 the Orlan was used since beginning of the Salyut space stations. The "Orlan M space suit" (M means here "modernized") that is presented now here, represents the last developing-step of the famous Russian space suit. The Orlan-M is an improved version of the previous spacesuit, the Orlan-DMA. It can accommodate a greater range of anthropometric sizes (165 cm to 190 cm). Radio communications have been modified so that two cosmonauts can speak and listen to each other simultaneously (which they couldn't in the previous Orlan version). ![]() The drawback is that the higher pressure means that the Orlan is somewhat more difficult to move in. The Orlan operates at a pressure of 0.4 atmospheres (EMU at 0.3 atm.), enabling a pre-breathe time of only 30 minutes (in the EMU pre-breathe is 12 hours in the Joint Airlock, or 4 hours in the EMU itself). The Orlan M space suit is very easy concepted: Through the its back the cosmonaut get into the space suite. All vital equipment is in the space suit on the back of the suit, however inside - e.g. fans, water pumps, pressure control valve, oxygene tubes and radio communication system. Each of the articles of equipment has a 1:1 back up system, i.e. if one of the vitally necessary systems should fail, immediately a duplicate takes over the supply.
