Why does Nasa delete the biggest moment in history?
Why was the Apollo 1 astronauts not saved?
How can the austronauts survive in space with all the radiation from the sun, and the 200 degrees, when their only protection was a thin layer aluminium folie?
Why is there an area in Area 51 that looks like the Moon?
What did they use 40 years ago?
The entire ascent stage structure is enveloped with a thermal and micrometeoroid shield, which combines a blanket of multiple layers of aluminized polyimide sheet (Kapton H-film) and aluminized polyester sheet (mylar) with a sandwich of Inconel skin, Inconel mesh and nickel foil or a polyimide blanket with a single sheet of aluminum skin. The blanket panels, formed in various shapes and sizes, consist (outboard to inboard) of 15 layers of 0.0005-inch-thick H-film. In a few ascent stage areas that have different thermal-protection requirements, the number of layers in a blanket panel varies slightly. Outboard to inboard, the the sandwich comprises a 0.0015-inch-thick Inconel skin and one or more layers of Inconel mesh alternated with 0.0005-inch-thick nickel foil. the number of Inconel mesh and nickel foil layers in a sandwich and the thickness of the aluminum skin vary considerably at different areas of the vehicle, depending on the duration and intensity of RCS thruster plume impingement at those areas. The combined thermal and micrometeoroid shield is mounted on low-thermal-conductive supports (standoffs), which keep it at least 2 inches from the main structure... The aluminum or Inconel skin (the outermost material) serves as a micrometoroid bumper; the sandwich and blanket material serve as thermal shielding...
The aluminized Mylar blankets insulate the structure against temperatures up to +350 (deg) F. On the TCA support truss members, which are subjected to temperatures in excess of +350 (deg) F due to engine radiation, an additional 20 layers of H-film are installed. H-film has an insulating capability up to +1,000 (deg) F. Additional H-film blankets are also used in other areas of the ascent stage that will be subjected to temperatures in excess of +350 (deg) F.

It was saved elsewhere.

Bogus question. The radiation is not that deadly, unless you remain unprotected for months and years at a time.

And you would feel comfortable wearing that 'protection walking into the hot spot at Three Mile Island?
Just asking...
When I get an X-ray that lasts seconds they give you a lead blanket... Heavy things... Why don't the med teams use those aluminum foil thingies NASA made so many years ago?
That one we can't take your word for, you cannot make a statement like that without proof

Utter rubbish! We are talking, here, ONLY about Apollo 11 footage. The color camera taken on Apollo 12 was accidentally aimed at the Sun, with the lens cap off, by Alan Bean (and boy did he feel bad about that!). Apollo 13, well never landed. SO, 14, 15, 16 and 17 all have good, color video. AND all of the landings have loads of still photos!!!

I'd be interested to see a technical comparison of them though, as in how much radiation they actually shield or what thermal properties they actually have, in numbers that can be compared.
