What Is Air Pressure?

You can think of our atmosphere as a large ocean of air surrounding the Earth. The air that composes the atmosphere is made of many different gases. Nitrogen accounts for as much as 78 percent of the volume, while oxygen accounts for 21 percent. The remaining one percent is composed of such gases as argon, carbon dioxide, helium and hydrogen. ...

Lunar Explorations

LunarExplorationsEver since the beginning of intelligent life on Earth, the moon has been a focal point of human curiosity. Galileo’s discovery in 1610 that the moon had craters, valleys and mountains, instead of the smooth surface previously believed, only added to a burning desire to learn more.

So when exactly did our up-close-and-personal explorations begin? It was in 1959 that the Russians started sending their Luna probes to the moon. The first man-made object to land (actually, crash) on the moon was Luna-2. That same year Luna-3 sent the first images of the far side of the moon – the side hidden from the Earth for more than 4.5 billion years. The USA caught up with the Russians in 1969 when the first manned mission, Apollo 11, landed on July 20. 'That's one small step for man, one giant leap for mankind,' Neil Armstrong proclaimed as he stepped onto the lunar surface. (He was supposed to say 'one small step for a man,' but he misspoke under the pressure of that historical moment.) Since that day, five more manned Apollo missions have landed on the moon. The last one, Apollo 17, left the moon on December 14, 1972, and no humans have returned since. All together only ten humans, none of them women, have walked on the surface of the moon.
