When and where did Skylab fall back to Earth?
Skylab fell back to Earth on 11 July 1979 and while most of it fell into the sea, quite a bit of the debris rained down on the Western Australian town of Esperance and surrounding areas. Most of the pieces were found on a 160km wide strip of land between the Perth-Adelaide highway and the Indian Pacific railway line.

It was the first space station built by American astronauts. It was abandoned in 1974. It re-entered and burned up in Earth's atmosphere in 1979.
Skylab was a space station launched and operated by NASA (the space agency of the United States) and was the U.S.'s first space station. Skylab orbited t…he Earth from 1973 to 1979, and included a workshop, a solar observatory, and other systems. It was inhabited by 3 different crews. The Skylab 1 crew (Pete Conrad, Paul Weitz, Joe Kerwin) was launched on May 23, 1973. They were charged with repairing the solar array panel that was damaged during launch. They also installed an umbrella on the outside of Skylab to keep the vehicle from overheating. Within days they were working on their experiments. Skylab 1 spent a total of 28 days in space. Each of the 3 Skylab crews set records for duration in space.The Skylab 2 crew (Alan Bean, Jack Lousma, Owen Garriott) launched July 28, 1973. They spent 59 1/2 days performing solar and earth studies from space.The Skylab 3 crew (Gerald Carr, Bill Pogue, Ed Gibson) launched on November 16, 1973 and spent 84 days working in Skylab.The last cew left Skylab on February 8, 1974.Skylab was destroyed when it reentered earth's atmosphere on July 11, 1979.
A satellite has to maintain a constant velocity of 8000 m/s in order to stay in Earth's orbit. If it gains mass or slows down at all, it will fall back into Earth's atmo…sphere.
Yes. It is falling around the sun. Its not falling into the sun because the earth is also moving perpendicular to the force of gravity. Gravity is constantly pulling on it but… at different angles so that the by the time the earth is moving in the direction the sun's gravity was pulling on it its now quarter of the way around it and the direction the sun is pulling on the earth is perpendicular that of the original state. Yes this means the astronautics are also falling. "Flying is learning how to throw yourself at the ground and miss" Douglas Adams
it fell on earth because back then we didn't do the extra boost they sometimes do now. The ISS now hovers around the earth and the gravitational force keeps it down like it do…es to the moon. But over time, it gets lower and lower. The correct altitude is 248 miles. Now its 220 and they are going to send a fuel supply to boost it up to its normal altitude. Back then they didnt do the boost therefore it fell

Satellites in orbit around Earth are travelling at very high speeds. Gravity makes them continually fall toward Earth, but because Earth is curved they travel around it. The …force the satellite experiences is a force that could be described as centripetal, or towards the center of the satellite's orbit. Assuming the satellite is a geostationary satellite, or that it maintains its orbit at relatively the same spot to the earth, this becomes a very simple idea of balancing forces. A satellite experiences a force Fg, or the force due to gravity. This force can be calculated by the equation: Fg = G*(ME*MS)/(ro)2 Where G is the gravitational constant, ME is the mass of the Earth, MS is the mass of the satellite, and ro is the radius of orbit (from the Earth's center). Since this force is centripetal, we can set this equal to: Fc = MS*v2/ro Where v is the velocity of the satellite. When you set this equal, you can solve for the velocity necessary to keep a geostationary satellite in orbit as a function of the height of the orbit. G*(ME*MS)/(ro)2 = MS*v2/ro (G*ME/ro).5 = v Since G and ME are constants, the relationship can be simplified to: v = (C/ro).5 This shows that the velocity needed to keep a satellite in orbit is inversely proportional to the square of the radius of orbit. Perhaps the most fascinating thing about this is that the mass of the satellite has no effect. (They simply require more energy to reach orbit.) Falling Satellites Satellites can eventually fall out of orbit, either due to some slight friction with the atmosphere (that slows them down), or because their orbits become otherwise unstable. Many will use manuevering (or station-keeping) rockets, small rocket engines attached to them that can be fired to keep their orbits stable. In the long term, we accept that satellites cannot be economically kept in orbit, and design them to have a limited lifespan. That is, we look at the satellite's proposed orbit, and, taking into account the amount of fuel that the on-board station-keeping rockets will have, calculate the maximum amount of time that the orbit can be maintained. This is the maximum operational lifespan of the satellite, and the rest of the on-board components are design to last just slightly longer than this. In other words, Planned Obsolesence - the satellite stops working just before it falls out of orbit.
Most of the water that falls from the clouds is called precipitation and so it will either fall back to lakes, oceans, rivers, or becomes evaporated water.
Satellites actually are falling back to Earth, but because they are travelling so fast around the the globe - they keep on missing. It's this balance of speed that also stops …them from floating away. Imagine a person holding a ball on a piece of string. If the person spins too fast the tension on the string will increase and the ball will want to fly off. If the person doesn't spin fast enough the ball is going to keep falling back to the person when released. But if the person spins at just the right speed they can maintain a balance in between the two.
They usually burn up in the atmosphere. occasionally they are large enough that pieces hit the ground.
The vast majority of man-made satellites orbiting the earth will indeed eventually have their orbit decay and fall back into the earth's atmosphere. However, many of the sat…ellites in a geosynchronous orbit or beyond (including several in highly eccentric orbits) will not fall back to earth - instead they will either fall towards the Moon, or, in most cases, simply exit the Earth-Moon system and wander the Solar System. The exact fate of a specific satellite depends entirely on its orbit at the time it runs out of maneuvering fuel and can make no more adjustments; it then is totally at the mercy of gravitational force.
Skylab orbited the earth from 1971 to 1979. It orbited the Earth 2,476 times during its 171 days and 13 hours that it was occupied from 1973 to 1974. This calc…ulates to roughly 14.4 orbits per day, or 1hour 40minutes per orbit. Skylab included several different missions, both manned and unmanned.
The official meteorological term is precipitation. According to the US Geological Survey, a sub-organization of the US Department of the Interior: "Precipitation is water rele…ased from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain."
This is called precipitation. It can be rain or snow.
