What are satellites and how do they help us down on earth?
Satellites are a smaller object that usually spins around a bigger object. An example of a satellite is the earth because it spins around the sun. Satellites are important to modern life because they can send radio signals back to earth so we can use objects like our phones or TV. They take photos of earth or other objects so that they can send them to scientists so they can research the earth or the object that they took a picture of.
A lot of Satellites have solar panels so they can turn sunlight into electricity for them to use. Most Satellites are made out of alloy which is light weight enough to be used in the satellite. Another material they use is titanium which is also a light weight material like alloy that could be used in satellites. Another material that some satellites use are plastic and aluminum that are used for specific parts. Some satellites use gold because it can resist and also have the ability to reflect infrared radiation in space.
