Oxygen Space suits cannot use normal air -- 78 percent nitrogen, 21 percent oxygen and 1 percent other gases -- because the low pressure would cause dangerously low oxygen concentrations in the lungs and blood,
Building the International Space Station (ISS) is much like building a toy using a child's LEGO or K'nex building block set. But whereas those playthings tend to be small in scale, the ISS contains thousands and thousands of parts [source: Hollingham]. Some of the major components are li...
Astronaut safety is paramount for NASA, and they've developed much better technologies to protect astronauts. All astronauts working outside the ISS now wear theSimplified Aid For EVA Rescue(SAFER) system. It's a jetpack that allows astronauts to return to the ISS if their tether fails or the...

During the course of its solar cycles, the Sun produces an array of different phenomena that we generally refer to as 'solar activity'. Much of this also falls under the category of 'space weather'. Firstly, regardless of what...
(11,265 km) and is made of 80% iron and around5% nickel and some lighter elements, such as carbon, oxygen, silicon, or sulfur. The density of Earth's inner solid core is as great as 12.2 grams per cubic centimeter, while the outer core has a density of around 13 grams per cubic ...
Fungi have been companions of mankind for millennia. Mushrooms inspired our eating culture, and yeasts and filamentous fungi were developed into highly efficient cell factories during the last 100 years to produce many products utilized in different indu
Ozone is pure oxygen, which, like all things, is poisonous in amounts more than the body can handle, which in this case isn't very much :) harlyquin8 years ago Yes. It is an unstable molecule, and it will break down everything that reacts to an Oxygen ion. Basically everything org...
That last point isn’t a given. There have been cases where pieces of deorbited craft have landed on the ground, such as with the Skylab space station, which fell from orbit in 1979, pieces of whichlanded in Australia. Large chunks of Skylab, like this oxygen tank, crashed into the Au...
What there are elements in our bodies like oxygen, carbon,calcium, they were all made inside stars. Well, there's hydrogen in us too.Hydrogen was made in the Big Bang, so there are parts of you that are as old asthe universe itself. Brian, thank you so much forshowing us the ...
