Image from https://vauxhallhistory.org/the-space-art-of-ralph-smith-in-vauxhall/ ‘In a November 1949 symposium, Harry Ross presented a paper on the “Lunar Space-Suit”. Ross had examined the problem of a 68 kg lunar space suit (equivalent to 11 kg on the Moon) which could be worn for up to 12 hours, within the temperature range of 120 degrees to minus 150 degrees Celsius, representing night and day. The suit design was a 4-ply, made up of a thin exterior skin of closely woven cloth. It had a 1 cm layer of cellular heat-resisting material (Kapok, wool, felt et cetera) and a 1-2 mm main airtight sheath of fabric-backed natural or synthetic rubber. It also had an interior lining of non-hygroscopic material, mainly for comfort and to manage contact between the rubber and skin and absorption of the water-vapour. ...’ https://www.bis-space.com/what-we-do/projects/the-lunar-space-suit Image from https://www.reddit.com/r/RetroFuturism/comments/nnycul/british_lunar_spacesuit_design_1947/ '... The exterior of the lunar space suit was to be a highly burnished metallic film, designed to reflect as much heat as possible. The chest and thigh areas were to be given an external matt-black finish to permit radiation manage heat loss. Operation of the suit during the lunar day would require further cooling through the use of a low boiling liquid such as Ammonia or water – which would vaporise to space through a thermostatic valve. The helmet was to be a light, rigid double-shell structure, with the inner a bright alloy metal and the outer a plastic with burnished metal coating. Lateral vision of 180 degrees was proposed with a minimal vertical extension in order to minimise heat gain or loss. ...' https://www.bis-space.com/what-we-do/projects/the-lunar-space-suit Image from https://www.reddit.com/r/RetroFuturism/comments/nnycul/british_lunar_spacesuit_design_1947/ '...
