The US astronaut wore the in-flight jacket on board his historic trip to the Moon in 1969.
Did someone here buy this? I'm thinking Jorge?
Beta cloth consists of fine woven silica fiber, similar to fiberglass. The resulting fabric does not burn, and melts only at temperatures exceeding 650 °C (1,200 °F). To reduce its tendency to crease or tear when manipulated, and to increase durability, the fibers are coated with Teflon.
Beta Cloth, aka beta fabric, is a white, PTFE-impregnated glass cloth commonly employed as an outer MLIB (Multi Later Insulation Blanket) layer due to its AO (atomic oxygen) resistance in LEO (Low Earth Orbit). It was heavily used on the Space Shuttle and continues to protect the interior and exterior of the International Space Station (ISS).
Beta cloth products are comprised of a high performance PTFE (Teflon™) and glass composite used as a component for MLI (multi-layer insulation) blankets. Often used as the outer layer, special design of the product provides the strength, resistance to flex fatigue and handle which sets it apart from other standard coated fabrics, and makes it more suitable for space applications. This lightly coated, low outgassing material has a great deal of flight legacy being used in proximity to sensitive components and equipment. In many applications, some properties or values are diminished by end of life as the effects of thermocycling, atomic oxygen, solar ultraviolet radiation, vacuum ultraviolet radiation, and space debris attack the exposed surface. Our Beta cloth fabrics are able to withstand these harsh conditions, serving as a barrier and protecting the inner surface.
This historic material is manufactured by Saint-Gobain Coated Fabrics in Manchester, NH USA and is supplied to the aerospace market exclusively by Bron Aerotech, Inc in Denver, Colorado. Bron Aerotech facilitated the successful re-qualification of beta cloth at aerospace OEMs when DuPont changed the Teflon formulation to reduce and then eliminate PFOA.
We supplied NASA (JPL) with beta cloth that is still protecting the nuclear power plant of Curiosity on planet Mars, 32 million miles from Earth.
I have a sample of beta cloth (I worked a few years as a subcontractor at Airbus Defence and Space). It's actually a quite common material in the space industry. the ISS is partly covered with beta cloth.
On the picture, the white cloth is beta cloth, the silver part is MLI (Multi-layer insulation) it's the "survival blanket" you see on many satellites (for example), and the orange part is kapton (another insulating material often in the form of adhesive tape).
Out of subject : the watch is a Poljot "Strela" chronograph (movement 3017) worn by Russian cosmonauts in the late 1960s and early 1970s.

This is an export version of this watch with an English dial. Soviet cosmonauts used watches with a Russian dial.
