Water On Mars!

The Mars Pheonix Lander is a small robitic rover about the size of a card table. It has been cruising around Mars near the North pole for over 5 months now. It was only supposed to last for 3, but hey, if it works, right?! Well, just in the past few weeks, Scientists have analyzed data from soil samples. There is definitely water on Mars! Since water is SO important to life on Earth, we think this makes it much more likely that Mars had (or has) life on it. Some people think that the origins of life on Earth might have come from Mars via a meteor. Who knows! In Fact, many are now suggesting that Mars once looked like Earth. Valleys and craters show evidence of water erosion and we now have found minerals that are only found in watery areas. Yes, ladies and gentlemen, the Universe is an Amazing Place! Keep Looking. Mars will be in the southwestern sky around and after sunset for the next few weeks, so look for a teeny reddish dot, your ancestors might have come from there!

Measure Me This

Ever wonder how big the Earth is?
People have been asking that question for as long as humans have been around. The cool thing is that we figured it out before we ever knew of light bulbs or computers. We figured it out before we had been to the north pole. Americans didn't even know Hawaii existed and we knew how much mass was in the Earth. So how did they do it?... Hmmmmm. Gravity is an interesting thing.

Measurement is so important to us. Imagine not knowing what time it was or how much money you had or never getting a pair of shoes that fit. Please always be sure to measure accurately.
