The Moon goes through "phases." That means it appears to us differently each night during its one-month orbit around our planet. We use terms like "Full Moon," "First Quarter," and "New Moon" to describe how the Moon appears (which we can't see because the lit side is facing away from us). The Moon does not produce its own light. Sunlight reflected off the Moon's surface is referred to as moonlight. As the Moon orbits Earth, the Sun illuminates the side of the Moon that is facing it. It's always a full Moon to the Sun! If you were looking down on Earth and its Moon from far above the North Pole, you would see a Moon that looked something like this: However, we can see the Moon from the canter of its orbit. As a result, we see different parts of the Moon's lit side. Make Moon phases out of Oreos. Then, to make the four major phases of the Moon, open up some Oreo cookies and scrape off the creme filling. These Oreo ...

  Orbits 'R' Us! The speed of the Earth's rotation from west to east at the equator  is 1675 km/h (1041 mph). The satellite receives a significant boost if it is launched in the same direction as Earth's rotation. It cannot benefit from this boost whether it is launched in the north or south. It also consumes a lot of fuel for the spacecraft's engines to alter the inclination, or tilt, of the satellite's orbit if it is launched toward the east. An orbit around the poles is highly inclined. The function of the satellite will determine which orbit is best. suspension of disbelief For instance, the two GOES* weather satellites are tasked with monitoring the weather across North America. Any developing situation, such as tropical storms forming in the Atlantic Ocean or storm fronts moving across the Pacific Ocean toward the west coast of the United States, must be "never taken their eyes off." They are, therefore "parked" in an orbit know...
