The Space Shuttle Since 1981, NASA space shuttles have been rocketing from the Florida coast into Earth orbit. The five orbiters — Columbia, Challenger, Discovery, Atlantis and Endeavour — have flown more than 130 times, carrying over 350 people into space and travelling more than half a billion miles, more than enough to reach Jupiter. Designed to return to Earth and land like a giant glider, the shuttle was the world's first reusable space vehicle. More than all of that, though, the shuttle program expanded the limits of human achievement and broadened our understanding of our world. EARTH'S Seasons - Zoom Astronomy Advertisement.

NASA Kids Club Skip to main content NASA Kids Club › Text Only Site Science Projects for Kids: The Incredible Universe" Science projects for kids: the incredible universe takes you to worlds just waiting to be discovered. With simple instructions and everyday materials, you'll be learning more about constellations with the kids. You can start with star gazing and watching shooting stars -- and then make a planetarium or star theater to bring what you've learned back home. Learn more about the planets and star brightness, and make an astrolabe.
How did the solar system form? The solar system is a pretty busy place. It’s got all kinds of planets, moons, asteroids, and comets zipping around our Sun. But how did this busy stellar neighborhood come to be? Our story starts about 4.6 billion years ago, with a wispy cloud of stellar dust. This cloud was part of a bigger cloud called a nebula. The Moon - Facts About The Moon For Kids the Moon was probably made 4.5 billion years ago when a large object hit the Earth and blasted out rocks that came together to orbit round the Earth. They eventually melted together, cooled down and became the Moon. For another 500 million years pieces of rock kept striking aginst the surface of the Moon. You can see the surface of the Moon by using a pair of binoculars or a small telescope. The Moon’s surface shows the damage caused by these large pieces of rock hitting it billions of years ago.
Planets For Kids - Solar System Facts and Astronomy New 2013 Phases of the Moon Animation Released A new animation highlighting the phases of the Moon has been released by the Scientific Visualization Studio at NASA Goddard Space Flight Center in Greenbelt, Md. The animation shows at hourly intervals, the geocentric phase, libration, position angle of the Moon's axis, and apparent diameter of the Moon throughout the year 2013. Topographic measurements by the Lunar Orbiter Laser Altimeter aboard the Lunar Reconnaissance Orbiter make it possible to simulate shadows on the Moon's surface with unprecedented accuracy and detail. "Thanks to Lunar Reconnaissance Orbiter, we now have excellent terrain maps of the Moon that can tell us the elevation at any point on the surface," said Ernie Wright, author of the new video from the Scientific Visualization Studio (SVS). "I use those maps to make the Moon sphere bumpy in all the right places. That allows the rendering software to realistically simulate all the shadows and the ragged terminator (the dividing line between day and night)."
Astronomy Picture of the Day Your Weight on Other Worlds Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass. We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things. The mass of a body is a measure of how much matter it contains. An object with mass has a quality called inertia. If you shake an object like a stone in your hand, you would notice that it takes a push to get it moving, and another push to stop it again. If the stone is at rest, it wants to remain at rest.
