His essays exemplified his skill at making complex subjects understandable, and were written in an unformal style, liberally sprinkled with personal anecdotes that endeared him to a legion of faithful readers. It was all a labor of love; in particular Asimov often remarked that of all his writing, his essays for The Magazine of Fantasy and Science Fiction were his favorite, despite the fact that he received the lowest word-rate payment for them. From November to Februaryan essay of his appeared in the magazine every month, without fail.

October 26, NASA A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: There are dozens upon dozens of natural satellites in the solar system, with almost every planet having at least one moon.

Saturn, for example, has at least 53 natural satellitesand between andit also had an artificial one — the Cassini spacecraftwhich explored the ringed planet and its moons. Artificial satellites, however, did not become a reality until the midth century.

The first artificial satellite was Sputnika Russian beach-ball-size space probe that lifted off on Oct. That act shocked much of the western world, as it was believed the Soviets did not have the capability to send satellites into space.

Explorer 1 was the first U. The United States' first satellite was Explorer 1 on Jan.

The satellite was only 2 percent the mass of Sputnik 2, What is a satellite essay, at 30 pounds 13 kg. The Sputniks and Explorer 1 became the opening shots in a space race between the United States and the Soviet Union that lasted until at least the late s.

Weather satellites improved forecasts, even for remote areas. Land-watching satellites such as the Landsat series tracked changes in forests, water and other parts of Earth's surface over time.

Telecommunications satellites made long-distance telephone calls and eventually, live television broadcasts from across the world a normal part of life.

A brief history of artificial satellites

Later generations helped with Internet connections. Earth Pictures from Space: Landsat Satellite Legacy ] With the miniaturization of computers and other hardware, it's now possible to send up much smaller satellites that can do science, telecommunications or other functions in orbit.

It's common now for companies and universities to create "CubeSats", or cube-shaped satellites that frequently populate low-Earth orbit.

These can be lofted on a rocket along with a bigger payload, or sent from a mobile launcher on the International Space Station ISS. The ISS is the biggest satellite in orbit, and took over a decade to construct.

Piece by piece, 15 nations contributed financial and physical infrastructure to the orbiting complex, which was put together between and Program officials expect the ISS to keep running until at least Parts of a satellite Every usable artificial satellite — whether it's a human or robotic one — has four main parts to it: As will be seen below, however, not all artificial satellites are necessarily workable ones.

Even a screw or a bit of paint is considered an "artificial" satellite, even though these are missing these parts. What keeps a satellite from falling to Earth? A satellite is best understood as a projectile, or an object that has only one force acting on it — gravity.

Technically speaking, anything that crosses the Karman Line at an altitude of kilometers 62 miles is considered in space. However, a satellite needs to be going fast — at least 8 km 5 miles a second — to stop from falling back down to Earth immediately.

If a satellite is traveling fast enough, it will perpetually "fall" toward Earth, but the Earth's curvature means that the satellite will fall around our planet instead of crashing back on the surface.A satellite is a moon, planet or machine that orbits a planet or star. The mouse that roared.

The satellite was silver in color, about the size of a beach ball, and weighed a mere pounds. Yet for all its simplicity, small size, and inability to do more than orbit. What is a satellite?

A satellite is a small thing orbiting or circling a larger thing. The complete path it follows is called an orbit. The moon is a example of a natural satellite of the earth.
