... where the crewmembers put on and take off their spacesuits. It's also the primary area for servicing and stowing the spacesuits. After exercising on the bicycle, spacewalkers float into the equipment lock where the ambient pressure is gradually lowered to 10.2 psi to help prepare their bodies for the ...

... of miles. When we leave our solar system and think of our galaxy, the Milky Way, it is so much more immense that we have to use different ways to describe distances ... sounds like a measurement of time, but it is not. It is a distance. A light year is about six million million miles, and the Milky Way is 100,000 light years across. We are about 20,000 light years from its edge. ---- Answer provided by Derek Webber Image:K2S logosmall.jpg Question and Answer extracted from the ...

Like the airline industry, it is expected that technology will make it possible for almost anyone of any age, who is physically able, to travel in space. ---- Answer provided by Sheryl L. Bishop, Ph.D. Image:K2S logosmall.jpg Question and Answer extracted from the book Kids to ...

The surface is pretty strange. We know from analyzing the infrared light reflected from Pluto that its surface is a mixture of a lot of different sorts of ice (ordinary water ice, plus frozen ... by Dr. John Spencer, Ph.D. Image:K2S logosmall.jpg Question and Answer extracted from the book Kids to Space - by Lonnie Schorer Image:9781894959421.jpg '''Buy This ...

The crewlock, which is separated from the equipment lock by a hatch, is where spacewalkers open the outer hatch and actually begin their excursions into space. The crewlock was built as small as possible to minimize the amount of precious air lost from the ...

... of the way. For smaller objects such as micro-meteoroids, we have layers of protection built into the skin of our modules that can stop them from penetrating the module skin. The skin is also equipped with a multi-layer insulation blanket that protects the modules from temperature extremes ...

... is measured in joules. One joule is equal to one Watt for one second. Imagine a one Watt light bulb being lit for one second. Kinetic energy is the energy of motion and is also measured in joules, equal to half the mass multiplied by the velocity squared. For example, one joule is the energy in a two kilogram mass moving at one meter per second. Imagine a two kilogram hammer swung at one meter per second. Mega-joule is a million joules ...
