So lets say that a meteoroid is coming to earth. You don’t know. You are watching TV. Suddenly a News Cast interrupts your show. The Newsman says that a meteoroid is coming to earth. You have three days. How did they know that? A satellite told them, do you want to know more? Read on for more info! First I’ll tell you what a satellite is, exactly. Second I’ll tell you how satellites find things. Third I'll tell you what happens when a satellite stop’s working. Fourth I’ll tell you why the satellite was invented. Fifth I’ll tell you about how big the first satellite was. Sixth I’ll tell you… well you’ll just have to find out yourself
What Satellites Do
This paragraph is about what satellites are, exactly. According to Brady Johnson, satellites are in orbit around the earth. I think satellites are really cool because they send signals to electronics on earth and so if you have a GPS usually you won’t get lost.
This paragraph is about how satellites find things. According to Suzannah, satellites use trilateration to find things. So if three satellites need to find something they can use trilateration to find stuff. Did you know that is also how GPS finds stuff?
This paragraph is about what happens when satellites stop working. According to Daniel Engber, satellites have to get away from earth and so it usually goes up to a higher place in space to get to a disposal orbit but usually most end up about 300 kilo meters above where it started. I didn’t know satellites died!
This paragraph is about why the satellite was invented. According to the FCC satellite-learning center, no one knows who first had the idea of satellites, but the first human-made object put into space was called “Sputnik,” which was launched by the Soviet Union on October 4, 1957. “Sputnik” means “companion” or “fellow traveler” in Russian. It was launched into a low-Earth orbit barely above the Earth's atmosphere. It was not used for two-way communications since it could only transmit a signal to Earth. I think that it would have been cool to see Sputnik launched into space.
This paragraph is about how big the first satellite was. According to Mr. Welch the first satellite was about as big as a basketball and a beach ball. But it was made of pure metal so it was really, really heavy.
This paragraph is about what they called the first satellite that worked. According to me, wink, wink, the first satellite that worked was called Sputnik. I remember it by thinking, spit on Nick, and can you seez it? Spit-Nick, Sput-nik.
This paragraph is about one way satellites help us. According to Gary Brown, Some newspapers and magazines are faster because they send their words and pictures to multiple printing sites via satellite to speed local printing.
Question: How did the satellite know that a meteoroid is coming to earth?
Answer: Satellites have little sensors that tell it if any thing breaks through the atmosphere around the earth. It sends messages to earth and takes pictures.
