This ties into the point mentioned above. This is a problem because the atmosphere can blur our images. This is why such telescopes are often built at very high altitudes if possible, such as the Mauna Loa Observatory in Hawaii. 1 What are the advantages and disadvantages of the Hubble telescope? Time consuming Regardless of the work that needs to be done with the Hubble Space Telescope, you can count on a long wait. This ties into the point mentioned above. Observatories tend to be located at higher altitudes -- 18 kilometers (11.2 miles) above the Earth near the equator and higher than 8 kilometers (5 miles) in the Arctic -- to preclude the effects of cloud cover. Sure, flying above the atmosphere and receiving the omnidirectional perspective that going to space gives you are definite victories for the space telescope aficionados; theres no way adaptive optics or a pristine observing site can compete with an observatory that doesnt have the Earth to contend with. Webb will have significantly larger field of view than the NICMOS camera on Hubble (covering more than ~15 times the area) and significantly better spatial resolution than is available with the infrared Spitzer Space Telescope. Ground-based observatories have an advantage here over space-based ones because they can enjoy a much greater field of view.

Why is the Hubble telescope better than telescopes on Earth? The Hubble Space Telescope travels through space with Earth in the background in this picture, taken after the fourth servicing mission in 2002. Wernher von Braun, one of America's leading rocket scientists who came from Germany after World War II, had already looked into the challenges of a space telescope with his team at the Marshall Space Flight Center in the 1960s. A raw Hubble image shows a satellite streak. advantage is that such telescopes are not encumbered by the The air also blocks out light from parts of the electromagnetic spectrum. Lacking essential data, scientists were unable to extrapolate information such as the age of the universe, the birth of stars, the existence of black holes and dark matter until the advent of space telescopes.

One plain example of an advantage of a telescope that is based on the Earth is the same advantage carried by all systems without remote components: If the telescope needs to be repaired or otherwise services, it can be done by human beings on the ground under normal conditions of gravity and oxygen. The European Space Research Organization (ESRO), later to become the European Space Agency (ESA), was also invited to participate in the project by producing inexpensive solar panels and taking part in observations and research.

The ability to put Earth telescopes in space, such as the famed Hubble telescope, could also be described fairly as transformative, at least within the worlds of astronomy and astrophysics. Expensive The impact of satellite trails on Hubble Space Telescope observations The Advantages and Disadvantages of Using a Ground-Based Telescope What are the advantages and disadvantages of the Hubble telescope? Counting all the repairs and fixes since it was put in orbit since 1990, the total expense is around $10 billion. With a primary mirror diameter of 2.4 meters (94.5 inches). In addition to providing an ever-larger range and pool of space objects to catalog and classify, telescopes have both indirectly and directly helped scientists understand more about "invisible" concepts, such as gravity, the speed of light and the basic laws of physics that govern everything known to exist.

Born in 1889, Hubble discovered that many objects previously thought to be clouds of dust and gas and classified as nebulae were actually galaxies beyond the Milky Way. One advantage the HST has over ground-based telescopes is that there is no atmosphere through which the telescope must look to gather its data. One of the most technologically advanced pieces of equipment that humans have put into orbit, Hubble has helped researchers make important discoveries about our universe, ranging from planets and stars to galaxies and cosmology. Indeed, the capability of observing ultraviolet light is a major advantage of the Hubble Space Telescope over larger ground-based telescopes. Repairs are difficult Any kind of repair work is going to prove to be difficult. SpaceXs Starlink satellites are manufactured at a facility in Redmond, Wash., and Amazons Project Kuiper operation is headquartered in Redmond as well. Hubble flies around, or orbits, high above Earth and its atmosphere. Another disadvantage for ground-basedtelescopes is that the Earths atmosphere absorbs much of the infrared andultraviolet light that passes through it. C) It is a special technology that allows the Hubble Space Telescope to adapt to study many different types of astronomical objects. Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earths atmosphere. Following intensive training on the use of new tools never used before in space, two teams of astronauts completed repairs during a record five back-to-back spacewalks.

Subsequent final assembly of the spacecraft did not take place until 1985. Why was the telescope such an advancement for the study of space? A list of space telescopes. Lower Cost Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope. The first advantage is that the HST is above the atmosphere, which enables it to observe in the ultraviolet, visible, and infrared regions of the electromagnetic spectrum. What is the major advantage of space based telescopes over Earth based Theyre easier to maintain and upgrade. Astronomers could now take advantage of a fully functional space telescope, and the public was treated to breathtaking photos of stars, galaxies, nebulae, and other deep-space objects. This is not because such telescopes are materially closer to their objects of inquiry, but rather because the Earth's atmosphere can distort images so badly.
