Another Earth-orbiting spacecraft, the Extreme Ultraviolet Explorer (EUVE) satellite, which operated from 1992 to 2001, surveyed the sky in the extreme ultraviolet region between 7 and 76 nm. This is absolutely not a duplicate of the other question. For example, they can detect certain planets, (I think they're considering this to avoid having to plan around eclipses, which can occur in L2 orbits). Fuel is needed for orbit maintenance as well as for attitude control. In space, however, telescopes are able to geta clearer shot of everything from exploding stars to other galaxies . So we have to send them to earth orbit above our atmosphere which filters radiations.Certain objects emit only radiation in UV range.So to study them we have to use UV ray telescopes. Since it will always be at the same location relative to Earth-in the midnight sky about 1.5 million km away - we can have continuous communications with it as the Earthwith rotates through the Deep Space Network". They can go through these Optical telescopes can be classified by three primary optical designs (refractor, reflector, or catadioptric), by sub-designs of these types, by how they are constructed, or by the task they perform. @RobJeffries I didn't mention it there, but that's mostly compared to the HCO that Spitzer is in. WebAn infrared telescope is a telescope that uses infrared light to detect celestial bodies. The satellite that contains the space telescope is injected into a low Earth orbit shortly after launch. A brief review of the IR sky and astronomical sources of infrared is followed by consideration of the advantages and disadvantages of IR astronomy, and problems from atmospheric absorption of infrared radiation.

Telescopes can also be classified by where they are placed, such as space telescopes. Another disadvantage for ground-basedtelescopes is that the Earth's atmosphere absorbs much of the infrared andultraviolet light that passes through it. The Deep Space Network is not needed to receive data from a satellite orbiting Sun-Earth L2, and the antenna on the spacecraft can be fairly simple. Does it also help that the dark side of Earth is the one facing L2, or is the difference minimal in the IR spectrum? Connect and share knowledge within a single location that is structured and easy to search. JWST sunshield is about 22 metres by 12 metres (69.5 ft x 46.5 ft). Would an accumulation of dust in a planet's L1 Lagrange point plausibly obscure it from Earth? Earths stratospheric ozone layer See all questions in The Electromagnetic Spectrum. Surprisingly, this alternative is rather expensive in terms of launch V. Later, when the satellite reaches apogee, another burn might be performed to raise perigee a bit (but not a whole lot). Telescopes in space are able to operate twenty-four hours a day, free of both Earth's day-night cycle as well as clouds and other weather conditions that can hamper observing. With balloons, they were able to reach about 25 miles (40 kilometres) up. Communication is easy; this is the cheapest of all alternatives regarding communications -- assuming the vehicle does make it to the intended geosynchronous orbit. international travelers, no matter where they may be, High noise immunity: not as likely to have interference from It revealed information about other galaxies, as well as information about the center of our galaxy the Milky Way. Fuel should be reserved for end-of-life activity. Ultraviolet radiation has wavelengths of about 400 nanometres (nm) on the visible-light side and about 10 nm on the X-ray side. The Webb Space Telescope will be positioned there. The other main benefit from being in L2 is that being so far away from Earth means that there is a much greater available field of view as the Earth blocks a very minor portion of the sky. Parking a telescope at a Lagrange point: is this a good idea from a debris point of view?
