Passage 1 [2020·原创]

When we talk about how the Earth and the other planets travel around the sun, we say they orbit the sun. Likewise, the moon orbits the Earth. Many artificial satellites(人造卫星) also orbit the Earth.

Satellites can orbit the Earth's equator(赤道) or go over the Earth's North and South Poles…or anything in between. They orbit at a low altitude(高度) of just a few hundred miles above the Earth's surface or thousands of miles out in space.

When it comes to satellites, space engineers have different types of orbits to choose from.

The choice of orbit all depends on the satellite's job!

The two GOES weather satellites, for example, have the job of keeping an eye on the weather over North America. They need to “never take their eyes off” any developing situation, such as tropical storms brewing(酝酿) in the Atlantic Ocean. Therefore, they are “parked” in what is called a geostationary orbit. They orbit exactly over the Earth's equator and make one orbit per day. Thus, since the Earth rotates once on its axis per day, the GOES satellite seems to hover over the same spot on the Earth all the time. GOES stands for Geostationary Operational Environmental Satellite.

On the other hand, satellites whose job is to make maps or study all different parts of the Earth's surface need an orbit that comes as close to passing over the North and South Poles as possible. This way, the Earth turns under the satellite's orbit and the Earth does most of the work of traveling! Also, the satellite should be close to the Earth's surface (a few hundred miles up) to get a good view with its imaging and measuring instruments.
