Suggested by <a href="/wiki/Lyman_Spitzer" title="Lyman Spitzer">Lyman Spitzer</a> in 1946, the first operational telescopes were the American <a href="/wiki/Orbiting_Astronomical_Observatory" title="Orbiting Astronomical Observatory">Orbiting Astronomical Observatory</a>, <a href="/wiki/OAO-2" class="mw-redirect" title="OAO-2">OAO-2</a> launched in 1968, and the Soviet <a href="/wiki/Orion_(space_telescope)" title="Orion (space telescope)">Orion 1 ultraviolet telescope</a> aboard space station <a href="/wiki/Salyut_1" title="Salyut 1">Salyut 1</a> in 1971. Space telescopes avoid several problems caused by the atmosphere, including the absorption or scattering of certain wavelengths of light, obstruction by clouds, and distortions due to atmospheric refraction such as <a href="/wiki/Twinkling" title="Twinkling">twinkling</a>. Space telescopes can also observe dim objects during the daytime, and they avoid <a href="/wiki/Light_pollution" title="Light pollution">light pollution</a> which <a href="/wiki/Observatory#Ground-based_observatories" title="Observatory">ground-based observatories</a> encounter. They are divided into two types: Satellites which map the entire sky (<a href="/wiki/Astronomical_survey" title="Astronomical survey">astronomical survey</a>), and satellites which focus on selected <a href="/wiki/Astronomical_object" title="Astronomical object">astronomical objects</a> or parts of the sky and beyond.
