However, the missions of these spacecraft last a short time, on the order of days to two weeks. In contrast, the International Space Station (ISS) was designed for long-term spaceflight and has been in orbit since 1998. So how is oxygen made aboard the ISS? It's handled in one of ...
The oxygen that people breathe in airplanes comes from the air outside. The air is supplied from the compressor stage of turbine engines and is passed through a bunch of machinery to ultimately be piped into the cabin for passengers. There is also an outflow valve, usually at the rear of ...
Meanwhile, reclaimed oxygen enters the ISS air supply [source: Starr]. While that's going on, drinking water gets recycled as some of these very mechanisms repackage exhaled air. Water is also reclaimed by collecting sweat, condensation and urine. (Plus, some crew-members get water from ...
In a way, plants, just like humans, also get used to the environmental conditions in which they live. Traditionally, roots grow and spread downwards due to gravity (roots absorb water and several vital nutrients from the ground). Still, in space, where the effect of gravity is negligible, ...
How hot does the thermosphere get? How much radiation is in the exosphere? How low is the oxygen in the exosphere? How big is the exosphere? How is the exosphere different from the thermosphere? What are the characteristics of the exosphere?
Randomly, at the top of Venus’s clouds is a layer where the temperature and pressure are similar to those on Earth, and because oxygen and nitrogen both rise in Venus’s dense atmosphere (like helium does on Earth), the air in that layer might actually be close to breathable. That’s...
A lunar mining facility harvests oxygen from the resource-rich volcanic soil of the eastern Mare Serenitatis. Credit: NASA/Pat Rawlings The lack of an atmosphere increases the chances of the surface being struck by comets and exposure to Solar Flares. The Moon also passes through the magnetotail...

(ii) A single-metal mechanism in which DNA cleavage is proposed to take place when the metal ion is at the 3′(A) site, as described in [12] (pp. 3438–3447). This model is also unlikely to be correct [25,26], noting that it does not explain why the catalytic tyrosine is in ...
What is this big room we’re in, and who put us here? What is that bright yellow circle on the ceiling and where does it go every night? Where does the ocean end and what happens when you get there? Where are all the dead people now that they’re not here anymore?
