Having a facility to investigate the effect of variable gravity levels would be very interesting from a scientific perspective. Some of the questions that might be worth finding the answers to are: How do various plants and bacteria respond to different gravity fields? How does this effect how they grow and the crop yields for plants? How does Lunar or ...

It would help you to learn which plants can grow properly in a greenhouse on the moon or Mars. When a seed germinates, the root starts growing downward with gravity, and the shoot grows upward to the surface of the soil. Light also helps to orient the plant, but it only works once the shoot has breached the surface of the soil. The angle of sunlight is ...

The biggest windows I can think of that can expose crew to a good dose of sunlight are the ISS' cupola, so those might be a good starting point. Like all the other US spacecraft windows I know of (except for the shuttle side hatch window) the cupola windows have coatings to keep out the UV. On each pane there is a coating to prevent reflection when the ...

Not modern, but Apollo used coatings on the windows of the command module and lunar module. Source: Apollo Experience Report: Spacecraft Structural Windows, NASA Tech Note D-7439. The CM windows were triple-pane (except for the telescope optics). The outer-most pane was made of fused amorphous silica and protected the cabin from micrometeroids, radiation, ...

This article from Air Space Mag (https://www.airspacemag.com/space/window-on-the-world-1142261/) says that the window for the Destiny module was designed as such (emphasis my own) The window’s glass is a special stock of high-purity, colorless, synthetic fused silicon dioxide—a material chosen for its resistance to the effects of thermal variations and its ...

It does seem that Lebedev and his crewmate Anatoliy Berezovoy did indeed suntan on Salyut-7. The NASA report references a column in 'Pravda', which published excerpts from the published diary of Lebedev, "Моё измерение: дневник космонавта", or "My dimension: a cosmonaut's diary". While it is hard to find the newspaper, the book can be ...

You have several kinds of radiation to deal with: Sunlight. Sunlight has a fair amount of UV. On Earth most of this is blocked by the ozone layer. Only a fairly small percentage gets through. Hence all the fuss and feathers about chloro-fluoro carbons (freon and friends) breaking down the ozone layer. On Mars you don't have enough free oxygen to form ...
