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.

Skylab was the first space station the United States launched into orbit, and the second space station ever visited by a human crew. Skylab was also the only space station NASA or the United States military launched alone. The 100 ton space station was in Earth's orbit from 1973 to 1979, and it was …visited by crews three times in 1973 and 1974. It included a laboratory for studying the effects of microgravity and the Apollo Telescope Mount solar observatory. It was launched as a docking station for space crafts and as an observatory for the goings on in space. (MORE)
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.

Is a warning shot fired from a gun into the air potentially dangerous when the bullet falls back to earth?
Yes . It's not potentially dangerous; it is dangerous. It's potentially fatal if it strikes someone.. Theoretically, the bullet would return to earth at the same speed it left the muzzle of the gun, but in practice that is not the case because air resistance would cap the speed of descent. T…hat's known as terminal velocity. Nevertheless, if the descending bullet struck you in the head at 180 to 200 miles per hour, there is little doubt that you would be severely injured or killed. Sad to say, numerous people are killed each year in New Year's celebrations (and other festivities) when people abuse firearms in such a manner. (MORE)
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 atmosphere.
in the Apollo 13 movie, upon reentry they say something about 34580 feet per second
The Earth has different seasons because it orbits around the sunmaking it further away during different times of the year. Earthhas fall as it moves further away from the suns energy.
Skylab was actually a converted second stage of a Saturn booster rocket originally intended for one of the Apollo missions that were cancelled.
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 (MORE)
It crashed back to Earth. Pieces of debris rained into the expected spot on Earth..

The service call Columbia provide a 36 mins boost to move Hubble's orbit by about 6km. Without a boost, Hubble and other satellites would fall back into earth's atmosphere, burning up on re-entry.
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 does 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 (MORE)
A Skylab is a science and engineering laboratory, was launched into orbit by a Saturn V rocket on May 14 1973.
Debris from Skylab was found between 31Â° to 34Â°S and 122Â° to 126Â°. An area south East of Perth Australia.
Evaporating water vapor rises to high altitudes, where thetemperature is low enough for the vapor to condense back intoliquid water. Generally the vapor condenses around small particlesof dust. The technique of cloud 'seeding' introduces smallparticles into clouds to facilitate the formation of rain…drops. Air currents raise the falling drops over and over. They get biggerand bigger, until they are too heavy to rise on the currents, andthen they fall to earth. (MORE)
Skylab was launched in 1973 and disintegrated when it reentered the Earth's atmosphere in 1979.

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 F g , or the force due to gravity. This force can be calculated by the equation: F g = G *( M E *M S )/( r o ) 2 Where G is the gravitational constant, M E is the mass of the Earth, M S is the mass of the satellite, and r o is the radius of orbit (from the Earth's center). Since this force is centripetal, we can set this equal to: F c = M S *v 2 / r o 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 *( M E * M S )/( r o ) 2 = M S *v 2 / r o ( G*M E / r o ) .5 = v Since G and M E are constants, the relationship can be simplified to: v = ( C/ r o ) .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. (MORE)
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.
Skylab's orbit gradually declined over the years it was in space. It had been in orbit for six years when it made its descent on 11 July 1979, with many chunks of hot debris falling across southern Western Australia. Most of the pieces were found on a 160km wide strip of land between the Perth-Adela…ide highway and the Indian Pacific railway line. (MORE)
As the number of space expeditions increased, there was felt a need to establish space stations in space where a team/mission sent to outer space could live for some time. They can remain functional for up to year's time. Skylab was the name given to the space station launched by the united states.
The Skylab Space Station weighed 169,950 pounds at takeoff. With an Apollo Service Module and Command Module attached, it would weigh 236,821 pounds, not counting crew and supplies. The station actually weighed slightly less because during launch, the sunshield and one main solar panel was lost, tho…ugh I am not sure of the weight without those components. (MORE)
Because their where plans for a new space station ( MIRR and years later also the ISS). Because Skylab becameunusefull they sended towards the atmosphere of the earth to burn up their.
The orange tank does not get retrived, it is left to burn up in the atmosphere. However, the two Solid Rocket Boosters attached to the side of the main tank do get collected as they fall into the ocean having detached 2 minutes after launch.
It wasn't intentionally abandoned. It was originally thought that the Space Shuttle would be operational before Skylab fell to earth. The Space Shuttle would then raise Skylab into a higher orbit to be used by multiple Space Shuttle crews, but an overabundance of solar flares caused Skylab to fall t…o earth 2 years before it normally would have. Delays in the development of the Space Shuttle spelled the demise of Skylab. (MORE)
When water falls back to earth as precipitation it may fall back in the oceans lakes or rivers or it may end up on land then what term is used for it?
When water returns to earth as precipitation it falls as rain, snow, sleet, hail, etc.
I try not to eat the stone to begin with :D But seriously, relativity doesn't deny the attraction between massive bodies. It just explains a little more precisely how that attraction works.

That depends on the reference we take.....If we take the velocity upwards to be +ve than the velocity downwards will be negative and vice versa....
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. (MORE)
What is the terminal velocity of a bullet falling back to the earth after it is shot straight in the air?
If the bullet were shot perfectly vertically in a vacuum, it would reach its maximum altitude, then fall at a velocity of 32 ft/sec/sec. The terminal velocity would depend upon the altitude reached by the bullet, which in turn depends upon the caliber and load of bullet shot.
Approximately what percentage of the total solar radiation that falls upon the earth is immediately reflected back into space?
Clouds: 24% of incoming solar radiation is reflected by clouds, Earth's Surface: 4% is reflected by the Earth's surface. Scattering; 7% of incoming solar radiation is scattered back to space (by bouncing offparticles in the atmosphere). Total: 35%
'Skylab' was the US's first space station, launched in 1973. It re-entered earth's atmosphere in 1979 and disintegrated, with pieces of debris striking western Australia.
Most rockets are intended to get out of Earth's atmosphere, but many do come back down eventually. Those that don't either have enough velocity and acceleration to get beyond enough Earth gravity to leave its orbit; others are set to exactly arrive at a particular orbit and stay there. This occurs b…ecause they are moving away from Eartha t the same rate they fall towards it. (MORE)
Skylab was launched on 14th May 1973 on top of a modified Saturn V rocket using surplus material from the Apollo Lunar program. Skylab re-entered Earth's atmosphere and was destroyed on July 11th 1979.
That will happen if they lose movement energy - usually due to atmospheric drag, if they are not high enough above Earth.
They usually burn up in the atmosphere. occasionally they are large enough that pieces hit the ground.
What is the minimum velocity required to project a body from a height h so that it will not fall back on earth?
if it was a continuous velocity then 10mps i guess because that is the terminal velocity when an object is dropped this is another person who answer actuallyn you are wrong terminal velocity is the maximum
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 satellites in a geosynchronous orbit or beyond (including several in highly eccentric orbits) will not fall back to earth - ins…tead 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.

The James Webb Space Telescope is scheduled for launch in 2018. The Webb telecope is not a direct replacement for the Hubble. The Hubble has been so reliable since its launch in April, 1990,that it's expected to function through 2014, and possibly as long as2020.
A modified upper third stage of a Saturn V moon rocket, it was the first USA space station, launched in 1973.

As a basic space st…ation it lead the way to the current space station in orbit. (MORE)
Gravity holds satellites in orbit. An orbit is by definition a fall. However, the satellite is moving so fast that the Earth falls away from the satellite as it falls to Earth. That's how they orbit. Another way to think of it is that the tendency of the satellite to escape orbit because of i…ts velocity (sometimes thought of as a "centrifugal force") is balanced by Earth's gravity. Things have a tendency to move in straight lines (because of "inertia") in the absence of forces like gravity. The combination of inertia and gravity produces an orbit. A lot of satellites do fall back to Earth, eventually. Slight frictional forces slow down the orbital speed of all satellites. The drag of the (thin at that level) atmosphere is usually the main cause of "orbital decay". The reason they stay in orbit so long is because of their elevation and speed. (MORE)
Skylab orbited the earth from 1971 to 1979. It orbited the Earth2,476 times during its 171 days and 13 hours that it was occupied from 1973 to1974. This calculates to roughly 14.4 orbits per day, or 1 hour 40 minutes per orbit. Skylab included several different missions, both manned andunmanned.
Skylab Is Falling - 2008 was released on: USA: 28 October 2008 (Chicago Childrens Film Festival)
Is it correct to say that satellites fall back to earth falling to earth because they are beyond the pull of earths gravity explain?
That is not English; that is not physics. Generally speaking, thespeed of the satellite and gravity cancel each other. As thesatellite slows (friction), gravity wins.
When sulfur dioxide reacts with water droplets in the air it forms a substance that falls back to Earth as .?
Sulfur dioxide reacts with droplets of airborne water to form 'AcidRain'. Oddly, acid rain has been found to decrease the amount ofgreenhouse gases in Earth's atmosphere. So, it can be said with some truth that the great reduction in acidrain in the US since the '70s may have resulted in a warmercl…imate, incorrectly called global warming. (MORE)

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." (MORE)
Has anyone ever thought that the reason we jump and fall back in the same place is because the earth is not moving?
That was the way most people thought centuries ago. We now knowwithout a doubt that Earth orbits the sun. The reason we fall backto the same place on Earth after jumping is because we are movingwith Earth and continue to do so because momentum is conserved. Anobject in motion will stay in motion at …the same speed and in thesame direction unless it is acted upon by an outside force. If youare flying on a passenger jet and jump up, you will land on thesame spot on the floor that you jumped from because you are movingat the same speed as the plane. (MORE)
It's travelling forward through space at sufficient speed tobalance out the effects of gravity. Either that - or it'ssufficiently far enough from Earth that gravity cannot pull it backto the surface. Here's two examples.. a TV satellite and the GPSnetwork. In the case of a TV satellite - it needs to… 'follow' the rotationof the Earth - so that it keeps transmitting TV to the same area onthe planet. TV satellites are in low orbits - and thus need to movefast enough to stop gravity pulling them back to earth. For the GPS network - the satellites need to remain stationary inorbit - in order for accurate data to be received by devices. TheGPS satellites need to remain in a static position - and thus areorbiting far enough from the Earth that gravity doesn't affectthem. (MORE)
