What are some reasons that we place telescopes on satellites in orbit around the earth instead of building them on the ground?

The atmosphere of the Earth filters out and blocks plenty of radiation from outer space. Thus, telescopes are placed on satellites to glean information from these rays that would otherwise not be able to reach Earth-based telescopes.

∙ 8y agoThe primary reason is that until recently, telescopic images taken from the ground encountered atmospheric distortion that made accurate optical imaging difficult or impossible, and interfered with radio astronomy. Orbiting satellites can get clear images across a wider variety of spectra.
Today, digital imaging and modern computers have enabled methods to reduce or eliminate distortion, using adaptive optics, multiple-point imaging, and similar technologies.

Why do single dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter?
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.
What do scientists build telescopes on top of?
Some telescopes are on the earth this is because they are easier to maintain as it does not require launches to get astronaughts up there to fix them. Also they are cheaper having to make a telescope usable in space takes time and money, it also requires a launch which is expensive as well. It is easier to view the results as you can view them directly from the telescopes, instead of them having to be sent from space down to earth using microwaves then you need an antenna and other.
What are the two reasons for land preparation?
Land could or can be prepared for building on or for farming,such as planting crops or grazing cattle or sheep.
What are some reasons why the damage from the earthquake was so severe?
the type of earthquake was a strong one and the building were not made to withstand an earthquake
The natural body in space that orbits a planet?
A natural celestial body that orbits a planet is called a satellite. Moons are satellites of planets. The Earth has one moon, but other planets like Jupiter and Uranus have many moons or satellites.
What are some reasons you keep building larger and larger telescopes?
because the people of the world suck their dicks very hard
What were some of the reasons that Jamestown nearly failed?
The settlers were looking gor gold instead of farming or building houses
Two reasons for sending telescopes into space?
One reason for sending telescopes into space is so that people can get a better look at the stars the second reason for this is so that scientist can discover more about stars.
Why do we use satellites?
As a planet, We use satellites for heaps of different reasons. The most common are for taking pictures of the earth to predict the weather and for the use of Gps devices. Satellites are very important because they can help predict some forms of natural disasters.
Give some reasons why artificial satellites are launched?
Satellites are used for a great many things. Communications satellites beam TV, radio, and telephone signals all around the world. Navigational satellites help people know where they are and get where they are going. Weather satellites take pictures of clouds and storms from above to help make weather forecasts. Spy satellites look down and snoop on other countries. Other satellites help scientists to study Earth and other planets
Why has the number of known satellites for the inner planets remained almost constant while the number of known satellites for outer planets has increased during the past 400 years?
Two reasons basically. One, the inner planets are a lot closer and therefore accessible by even modest telescopes. We know that Mercury and Venus have no moons and Mars has two small ones. Beyond that optical telescopes on earth have a little trouble seeing something as small as a moon from that distance. Which brings us to reason two - spaceships. The spacecraft we've sent to the systems of Jupiter and Saturn have discovered literally dozens of previously unknown moons. They were simply too small and too close to their primaries to show up on earth-bound telescopes. We've also gotten our first good looks at Saturn's rings and probably posed more questions than we answered.
What are 2 reasons for sending telescopes into space?
Telescopes in space are able to view objects clearly without having to look through a thick layer of the Earth's atmosphere. This enables them to capture better pictures and observe dimmer and more distant objects.
Explain why earth has only one satellites?
I've never seen a book that deals with this question. But I suspect that if the questioner is able to discover an answer some day, the answer will be related somehow to the reasons why Mercury and Venus have no satellites, why Jupiter and Saturn have at least 60 satellites apiece, and why the sun has only eight or nine planets.
What were Constantines reasons for building Constantinople?
so he can have his own capital.
State four reasons for building a nation?
Four reasons for building a nation might include creation of a national identity, cohesion of a society, cohesion of government, and the creation of economic stability.
