Projekt Satellite Zodiac

short project description

Since the majority of the world's population now lives in cities, starry nights have become increasingly rare. However, our life is dominated by artificial heavenly bodies. In my installation I make satellite positions visible – the room becomes a planetarium, with satellites replacing stars. Laser pointers display the positions of satellites. Additionally, illustrative interpretation of the emerging (satellite-) constellations explain their meaning and reflect our technological contemporary mythology. The C64, iPod, Gameboy and Walkman are among zodiac symbols of satellite constellations.

Stars are decorations of the night sky. Their arrangement have ever since been subject to explanation based on the contemporary cultural framework. This pattern interpretation has created the so called modern (western) constellations. The majority of which depict animals (Aries, Aquila, Dorado, Taurus, Cancer, Leo, Scorpio, Capricorn, Pisces, Canis Major, Canis Minor, Lupus, Lynx and so forth), followed by roman, greek and babylonian mythological characters (Andromeda, Aquarius, Auriga, Hercules, Pegasus, Perseus, Orion, Virgo and others). Already the third biggest group of constellations are man-made machines – pieces of technology like an the arrow (Sagitta), the triangle (Triangulum), the balance (Libra) and the lyre (Lyra). But there are also more curious ones like a ships keel (Carina), poop deck (Puppis) and its sails (Vela), an air pump (Antlia), a pair of compasses (Circinus), a carpenter's level (Norma), a mariner's octant (Octans), and compass (Pyxis), a eyepiece graticule (Reticulum), a telescope (Telescopium), a pendulum clock (Horologium), a microscope (Microscopium), a chemical furnace (Fornax), a sculptors chisel (Caelum) and a painter's easel (Pictor). Those constellations were given names by the french theologist and scientist Nicolas Louis de Lacaille (1713-1763) during an astronomical expedition to study the southern heavens at the Cape of Good Hope. When Lacaille looked up to the nightly firmament he saw the high-tech equipment of artists, craftsmen, seafarer and scientists of his time. Like a Rorschach test he made his sense of the patterns in the sky according to his conditioning. If the stars would miraculously appear rearranged night – how would we name the new constellations? Wind generator, Pedelec and iPad?

Since a majority of the world's population now lives in cities, starry nights have become increasingly difficult to witness. The chances are that it's easier to get a women's magazine at a newsstand an read an extensive horoscope. Astrology proclaims to have powers on our lives, however, our everyday life is dominated by artificial heavenly bodies. The times are at an end when stars meant guidance and orientation. Navigation and positioning is the domain of man-made orbital vessels. Guidance systems from missiles to cars use satellites triangulate the position. Weather forecasts are based on remote sensing satellite imagery. Communication and television is transmitted over satellite dishes. We know the size of the ozone hole just as well as iranian nuclear sites from a satellite's perspective. Every day satellites will most likely have impact on your routine - yet for the most part they stay invisible and their names and constellations remain obscure.

Satellites reflect sunlight to the earth rendering them visible to the eye just shortly after sunset, when their orbital position is still in the sunlight and just before dawn, when it is already in it. Most satellites are registered and their orbits are published by the authorities. Some “secret” ones aren't, but a small group of amateurs hunt them down for their diversion, calculating the orbits by collecting individual spottings from different times and points around the globe. Figuring the orbital data out makes prediction for future passes and subsequently adjustments to the orbit possible. The enthusiasts exchange their findings through the See-Sat e-mail list.

Satellite Zodiac is a taxonomy of satellite constellations to give satellites visibility and meaning. Satellites can either stand still relative to our position or move on asynchronous paths with different speeds depending on their orbital type. The constellations are therefore determined by time and location. They are ephemeral by nature, existing only for fractions of a second. A theory of satellite constellations must allow for those special circumstances of moving objects in different orbital planes.

Satellite Zodiac is an installation where motor controlled laser pointers display the current position of up to 12 moving satellites in our field of view in real time plus the belt of geosynchronous satellites - the satellites milky way. Just like in a planetarium where the star constellations can be displayed, illustrative interpretation of the emerging (satellite-) constellations explain their meaning and reflect our technological contemporary mythology. The C64, iPod, Gameboy, Polaroid and Walkman are among zodiac symbols of satellite constellations.

The satellite zodiac project was made possible with the support of the Thuringia Arts Council (Kulturstiftung des Freistaats Thüringen).
