Satellites!

Satellites are important things in our lives because they provide us the ability to make a phone call to the other side of the world. They also give us internet to use sites to communicate or be entertained, when i say entertained I mean it gives us television programs that are entertaining. Satellites are orbited so as the earth. Why they are orbited its because they orbit around something large things and satellites orbit around the earth and the earth orbits around the sun. They are also meticulously engineered which means they were built very very carefully. Gravity is the key that helps the satellites roam around space. The first satellite was actually made out of aluminum and four antennas which is pretty bad compared to the ones we have now. Did you know the first satellite was actually named a weird name Sputnik 1. On satellites there is a platform called a bus, attached on the platform are antennas, cameras, telescopes and communication devices. Satellites power themselves which is pretty impressive, how are they powering themselves? it is done by using large solar wings covered with light solar cells. The wings also known as arrays can be turned on to collect as much light. Arrays become less efficient as time goes by.
