The costs of the Hubble Space Telescope have been estimated to be between $1.5 to $2.1 billion . 1672, P.R.S. The main reason we put telescopes into space is to get around the Earths atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. This ties into the point mentioned above. Disadvantages and limitations of Earth based optical telescopes They can only be used at night. Which country ruled the world the longest? The detail is absolutely extraordinary When you can eliminate the atmosphere, you have a degree of clarity that is still largely unmatched. Optimal ground telescope operation requires low temperature and pressure conditions, but instruments in space don't require environmental stability because space is devoid of large fluctuations in lighting, temperature and pressure. The air also blocks out light from parts of the electromagnetic spectrum.

Space.com: Why Are Space Telescopes Better Than Earth-Based Telescopes? The future of telescopes appears to be advanced ground-based telescopes for frequencies of light that make it through the atmosphere, and space telescopes to lift our eyes above the atmosphere of Earth, which will always block most wavelengths of the em spectrum. During the EVAs, COSTAR was installed and the Wide Field/Planetary Camera was replaced with the Wide Field/Planetary Camera 2, which was designed to compensate for the mirror problem. 1 What advantages does the Hubble space Telescope have over ground-based telescopes?

The system designed to correct the error was designated COSTAR, for Corrective Optics Space Telescope Axial Replacement. The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry. What are some advantages and disadvantages of interferometry over individual telescopes? 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. For optical telescopes such as the ones being discussed, the only real advantage of putting a telescope in space is that it can do its job much better there. 17 Perhaps the most famous telescope to suffer from spherical aberration was the Hubble Space telescope or HST. COSTAR was a set of optics that compensated for the aberration and would allow all of Hubble's instruments to function normally.
