  NASA puts spacesuit worries to rest - Space.com- msnbc.com
The ban was largely a precaution in case the incident was due to a generic flaw in NASA spacesuits.
While engineers have not completely identified root cause of the Earth-based suit's smoky odor, the leading candidate is the specific canister used to remove carbon dioxide from the spacesuit's 100 percent oxygen interior, she added.
Because of the high flammability of a spacesuit's oxygen-rich atmosphere, NASA has to take any hint of smoke or combustion seriously in order to ensure the safety of spacewalking astronauts.

 ESA - ESA Permanent Mission in Russia - Orlan spacesuit
The semi-rigid Orlan-D spacesuit was first worn for a spacewalk on 20 December 1977 by Soviet cosmonauts Yuri Romanenko and Georgy Grechko, the crew of the Salyut–6 space station.
The Orlan spacesuits are designed by NPP Zvezda, a science and production enterprise in Tomilino, near Moscow, and their origins date back to the L-3 Lunar Programme.
After the benefits of semi-rigid spacesuits were verified by testing, and on the assumption that EVAs would become common on board an orbital station, the designers at Zvezda produced two options: the lightweight emergency rescue attire and the more refined, reliable and heavy EVA spacesuit, of the Orlan type.

  2001 Spacesuit
The 2001 Spacesuit Restoration Project is a project to restore a 2001 spacesuit based on surviving pieces of original 2001 spacesuits.
These spacesuits feature silver fabric suit bodies, white helmets, a very small oxygen tube from the backpack to the helmet with no helmet mounted hose connector, no leg mounted mating ring for attaching the ring of the boots, and brown/tan colored boots.
This is apparent as the spacesuit legs have mating disconnect rings for the boots and the helmets have the large oxygen hoses as did the Discovery suits.

 Ham radio operators: spacesuit still alive, giving weak signals   (Site not responding. Last check: )
Ham radio operators reported Sunday that an old Russian spacesuit, dubbed "Ivan Ivanovich" and stuffed with clothes and a radio transmitter, was again sending weak signals as it circled the globe.
The spacesuit also was supposed to transmit pictures, artwork and lessons for schoolchildren on the ground.
Members of the ham radio association weren't sure if the problem was with the spacesuit's antenna on its helmet, a feedline to the antenna or a connector on the transmitter, said Rosalie White, program manager at ARRL, a sponsor of the project.

 Spacesuit
century, there have been all sorts of visions of what the spacesuit would look like, though by the 1940s these had settled down into two distinct types: the heavy, armour-plated number for men, and the form-hugging spandex cat-suit with transparent goldfish-bowl helmet for women.
A spacesuit is in many ways a miniature spaceship-- sometimes even with miniature rockets for manoeuvring.
However, the spacesuit has the added problem of needing to be light enough for a man to wear (even in weightlessness mass is a factor because it determines how hard you're going to bump into something) and it has to be flexible enough to allow him to move about and work.

US spacesuits have been pressurized at 0.30 bar (30% earth sea level pressure), but because the gas in the suit is 100 percent oxygen instead of 20 percent, the person in a spacesuit actually has more oxygen to breathe than is available at an altitude of 3,000 m without the spacesuit.
