4 . A satellite is an object in space that orbits around another. It has two kinds — natural satellites and artificial satellites. The moon is a natural satellite that moves around the earth while artificial satellites are those made by man.
Despite their widespread impact on daily life, artificial satellites mainly depend on different complicated makeups. On the outside, they may look like a wheel, equipped with solar panels or sails. Inside, the satellites contain mission-specific scientific instruments, which include whatever tools the satellites need to perform their work. Among them, high-resolution cameras and communication electronics are typical ones. Besides, the part that carries the load and holds all the parts together is called the bus.
Artificial satellites operate in a systematic way just like humans. Computers function as the satellite’s brain, which receive information, interpret it, and send messages back to the earth. Advanced digital cameras serve as the satellite’s eyes. Sensors are other important parts that not only recognize light, heat, and gases, but also record changes in what is being observed. Radios on the satellite send information back to the earth. Solar panels provide electrical power for the computers and other equipment, as well as the power to move the satellite forward.
Artificial satellites use gravity to stay in their orbits. Earth’s gravity pulls everything toward the center of the planet. To stay in the earth’s orbit, the speed of a satellite must adjust to the tiniest changes in the pull of gravity. The satellite’s speed works against earth’s gravity just enough so that it doesn’t go speeding into space or falling back to the earth.
Rockets carry satellites to different types and heights of orbits, based on the tasks they need to perform. Satellites closer to the earth are in low-earth orbit, which can be 200-500 miles high. The closer to the earth, the stronger the gravity is. Therefore, these satellites must travel at about 17,000 miles per hour to keep from falling back to the earth, while higher-orbiting satellites can travel more slowly.

I had just finished my dance class, and it was a disaster: I started on the wrong foot and couldn’t get the steps that other students seemed to do easily. I began to doubt my talent for ballet.
Just then, my big sister Julissa arrived. She took one look at me and asked, “What’s wrong Lakeisha?”
“Nothing,” I said quietly. I was too shy to be perfectly frank with my sister.
“Uh huh,” Julissa replied. “Looks like a bad ‘nothing’ to me, so tell me what happened.”
“Well,” I mumbled (咕哝), “maybe I shouldn’t be taking dance classes? It felt like I was the only one who couldn’t land her pirouettes (单脚尖旋转) today.”
“Listen,” she said, “not every day is a great one, and not everything you try is going to work out the way you want. The point is to keep trying. Remember that and you’ll be fine.”
“I tried my best, but…” I replied.
Looking at me seriously, Julissa said, “Maybe ballet is not your thing, but dance is. I see how beautifully you shake and move all the time. There are all kinds of ways to dance, so maybe you just need to find your own style. Why not stick to jazz dance? You are so good at it.”
I thought about her words and my performances carefully. Yes, why had I never thought of that? I wanted to be a ballet dancer, but it may not be a good choice for me. It seemed as if I suddenly saw the light
“You’re right,” I replied. “Thank you. I’m so lucky to have you to guide me!”
