Robotic Telescopes Enable Advanced Antarctic Observations

Antarctica is more like interstellar space than any other place on earth. It is extremely cold‚ dry‚ calm‚ and extra dark with clear seeing to great cosmic distances. As a result‚ a telescope just a few meters tall near the South Pole can make observations as good as larger telescopes at more temperate locations and study the same objects that space satellites can study [1]‚ but at lower cost without sending telescopes into orbit [2]. But installing a telescope in Antarctica is not easy. It requires the use of a giant ice-breaker ship‚ track-wheeled tractors pulling huge storage containers‚ and a crew of woolen boot- and parka-clad “expedition astronomers” [3]. In 2005 a Chinese expedition became the first to reach the peak of the Antarctic ice cap‚ the highest point on the Antarctic Plateau 4093 meters above sea level. It was called Dome Argus‚ now known as Dome A.
