The ESA Space Debris Telescope is located at the Teide Observatory on the island of Tenerife, Spain. The telescope is ESA's Optical Ground Station forming a part of the Artemis experiment. As a large part of the observation time is dedicated to space debris surveys, in particular the observation of space debris in the geostationary ring and in geostationary transfer orbits, the term ESA Space Debris Telescope became used very frequently. Space debris surveys are carried out every month, centered around New Moon.
The telescope is a Ritchey-Chrétien telescope with an aperture of 1 m and field of view of 0.7 degrees, equipped with a cryogenically cooled mosaic CCD-Camera of 4k*4k pixels. The detection threshold is between 19th and 21st magnitude, which corresponds to a capability to detect space debris objects as small as 15 cm in the geostationary ring.
Famous quotes containing the words space and/or telescope:
“To play is nothing but the imitative substitution of a pleasurable, superfluous and voluntary action for a serious, necessary, imperative and difficult one. At the cradle of play as well as of artistic activity there stood leisure, tedium entailed by increased spiritual mobility, a horror vacui, the need of letting forms no longer imprisoned move freely, of filling empty time with sequences of notes, empty space with sequences of form.”
—Max J. Friedländer (1867–1958)
“The telescope at one end of his beat,
And at the other end the microscope....”
—Robert Frost (1874–1963)
