Location of Antarctica Schmidt telescopes

[edit on Wikidata]

The Antarctica Schmidt Telescopes project (also known as Antarctic Survey Telescopes (AST3)) is a joint project between Texas A&M University (TAMU) and the Beijing Astronomical Observatory to build three small (50cm aperture) wide-field telescopes at the Antarctic Kunlun Station near Dome A in Antarctica; Lifan Wang at TAMU is the main instigator of the project. [1][2][3]

These telescopes will take advantage of the low background and the long Antarctic nights to provide high-accuracy photometric time series for finding extrasolar planets, and to observe wide fields in the infrared to look for new supernovae.

The first of three Antarctic Survey Telescopes AST3-1, was installed at the Antarctic Kunlun Station in April 2012. 2nd and 3rd telescopes will be installed in 2013 and 2014 [4]

An update was published indicating that the first telescope operated for only a few weeks in 2012 before a power failure, and was repaired in 2013, but the CCD controller proceeded to fail after further data collection. The AST3-2 unit has seen several design revisions to improve reliability in the harsh Antarctic environment, and was tested over the 2013-2014 winter in Mohe, China before being sent to the field.[5]
