Life Support
•Life support, or as NASA refers to it “Enviromental Control”, is a group of devices that allow a human to survive in space. •These systems include: food, water, oxygen, carbon dioxide removal, waste management systems and thermal temperature control to name a few. •Other systems may include radiation and micro-meteorite protection elements as well.
•All water is re-used in spaceflight, consider that if you ever want to travel in space.
•The best defense to radiation is not lead in space, but rather, normal h2o filled walls. Radiation sources are primarily high-energy particles from the Sun.

On Apollo flights, the ship would continually perform a very slow roll in respect to the sun to slowly bake and cool sections of the spacecraft. If it hadn’t, one side of the spacecraft would stretch and the other would shrink to such a degree, cracks/leaks could form, causing a rupture of the hull and exposing the astronauts to the vacuum of space..

Sun Radiation - This caused what was a mystery during the early space flights where astro/cosmo-nauts would report seeing flashes of light in the space craft. These high energy particles travel through the spacecraft skin, into our water filled eyeballs, and register to us as a flash of light when it interacts with the water particles within.
