Curiosity's Revolutionary Experiments

When the Rover Curiosity landed on Mars, space and science fans all over the world rejoiced. But it is not there just to take pictures. This incredible piece of machinery is a one-ton, all-inclusive laboratory, capable of analyzing all aspects of the Martian surface and atmosphere.

It's primary goals include investigation of the climate and geology, assessment of whether or not Gale Crater has ever offered life-sustaining environmental conditions, investigating the role of water on mars, and planetary habitability studies in preparation for future human exploration.

This video incorporates photography and video from the Mars Rover as well as CGI animations of the many components at work. Watch as Curiosity stretches its legs in preparation for the truly revolutionary experiments on its calendar for the weeks and years ahead.

3 Chemistry Experiments That Changed The World

Chemistry is the study of matter - stuff, and how it interacts with other stuff. Even though chemistry doesn't make a lot of news these days, chemists are making discoveries that change lives all the time. If Hank had to narrow down all of chemistry's flashes of brilliance into the most awesome experiments in history, he would narrow it down to these three.
