What Can Satellites Do?
Have You Ever Wondered...
- What can satellites do?
- How many satellites orbit the Earth?
- When was the first satellite launched into orbit?
Without these things, our circadian lives would look much different. Some of us couldn't optically canvass television. Some of us couldn't decipher how to navigate from one place to another when peregrinating. Some of us could be imperilled by deplorable weather that we didn't ken was peregrinated. What are we verbalizing about? Satellites, of course!
Satellites are any objects that revolve around (orbit) another object in space. Some satellites are natural, while others are artificial (man-made). The moon is an example of a natural satellite that orbits the Earth. We're going to focus, though, on the man-made satellites.
Artificial satellites are machines that humans launch into orbit, conventionally around the Earth. Artificial satellites can be sent to orbit other planets, additionally. For example, the Hubble Space Telescope has been sent throughout space to orbit sundry planets.
The Soviet Coalescence launched the first artificial satellite — Sputnik 1 — on October 4, 1957. The Coalesced States launched its first artificial satellite — Explorer 1 — about four months later.
Since that time, over 2,500 satellites have been launched into space. Would you have ever conjectured there are that many satellites up there in the firmament, peregrinating around the Earth perpetually again?
What in the world do they do up there? Why do we require so many of them? Artificial satellites are utilized for all sorts of purposes. Satellites like the Hubble Space Telescope, the International Space Station, and the Russian Mir space station avail scientists explore space in incipient and exhilarating ways.
Communications satellites avail us communicate with people all over the world. Weather satellites avail us observe the Earth from space to avail soothsay weather patterns. Radio and television satellites beam our favorite musical compositions, movies, and television shows to Earth for us to relish.
There's even a group of 27 satellites that make up the Ecumenical Situating System (GPS). Without these satellites, we couldn't utilize GPS contrivances to find our way while peregrinating.
If you're wondering how that many satellites stay in orbit without bumping into each other, just recollect that space is very…well…spacious! Compared to our quantifications on Earth, the size of space seems illimitable.
Even though there's a plethora of room in space, satellites are launched into orbits at different distances from Earth. Some may be as proximate as 150 miles above Earth, while others may be as far away as 20,000 miles or more.
Most artificial satellites orbit within 500 miles of Earth or what scientists call low-Earth orbit. These satellites have to peregrinate very expeditious — about 17,000 miles per hour — to eschew being sucked back into Earth's atmosphere.
Sooner or later, though, the force of gravity will pull all objects, including artificial satellites, back to Earth. When satellites quit working, they become orbiting “space junk" until gravity pulls them back to Earth. Albeit at least one piece of space junk returns to Earth every day, it's infrequent that anyone ever descries. So no desideratum to worry that the empyrean is falling!
