Lowell Observatory technology to be telecast on the Discovery channels. The primary mirror of the Discovery Channel Telescope will be in diameter, with an uncommon meniscus design for such a large mirror. This mirror was ground and polished into its parabolic shape at the Optical Fabrication and Engineering Facility of the College of Optical Sciences of the University of Arizona (in Tucson, Arizona). Lowell Observatory's astronomers conduct research on a wide range of solar system and astrophysical topics using ground-based, airborne, and space-based telescopes. Among the many current programs are a search for near-Earth asteroids, a survey of the Kuiper Belt beyond
Lowell (Martian crater) then started observing Mars intensively for years. He used the observatory and his large refractor telescope to discover over 500 canals on Mars. Lowell promoted the idea that they were constructed by an intelligent race of Martians. However, when pictures were received from spacecraft, the canals were found to be optical illusions. Nevertheless, much of the later interest in Mars exploration resulted from the efforts of Lowell. Lowell (Martian crater) The Lowell Crater is a large impact crater on Aonia Terra in the Thaumasia quadrangle of Mars. The crater is about 203 kilometers (127 miles) in diameter. Lowell Crater has
