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 ...
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 ...
The main engines provide the remainder of the thrust (29 percent) to lift the shuttle off the pad and into orbit. The engines burn liquid hydrogen and liquid oxygen, which are stored in the external fuel tank (ET), at a ratio of 6:1. They draw liquid hydrogen and oxygen from the ET...
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, ...
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...
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?
How much does the AG gravity level affect the spin rate thresholds that trigger negative reactions? What are the lowest AG levels for easy walking, sitting in a chair, drinking or eating at a table, etc.? Do people really enjoy Moon and Mars-level AG, if the spin is slow enough to av...
Then, 11 years after NASA dashed his astronaut dreams a second time, he won the MoonDAO draw and started preparing to gobeyond the Kármán line. Related: The Kármán Line: Where does space begin? Excitement, disbelief and doubt As his flight with Blue Origin approached, Jahangir was filled...
radiation out into space, keeping the planet cool. But when the radiation does reach Earth's surface, the planet itself reflects solar radiation out into space at night — unless there are thin clouds like contrails in thenight sky. Those clouds can trap the reflected solar radiation and ...
