Out of this World
How much do you weigh on Mars? How many moons does Saturn have? Let your imagination leave this world and travel to other planets. Study an actual moon rock recovered from Apollo 17 and grasp the properties of aluminum-lithium alloy. Launch a rocket to explore the effects of air pressure; climb into a space capsule and blast into outer space.
From the German word for ball, the kugels are giant spheres of granite that depict features of planet Earth and the Moon. The big one (Earth) weighs 29 tons and rolls with only 33 pounds of pressure per square inch—that’s less pressure than your faucet at home! The Kugels are mounted in the scale of one foot to 1,000 miles.
How can we be sure that planet Earth spins on an axis? Léon Foucault knew. His 1851 invention provided science with a simple mechanism for learning about the earth’s rotation. Witness the pendulum in action as it knocks over a peg every 15 minutes.
Let your imagination travel to astronomical altitudes. Marvel over how the moon’s phases change the night sky. Touch a rock from outer space. Learn how to spot the Big Dipper and discover which stars you can see from your backyard tonight.
In 1977 NASA launched Voyager 1 and 2, two probes boldly going where no spacecraft had gone before! After 35 years of zipping through space these ultimate inanimate explorers still work and are still communicating with us! The Voyager program has been a vital source of information used by astronomers in understanding more about our own cosmic back yard.
