Korea joins giant telescope
DOI: 10.1063/1.4797089
On 6 February, South Korea joined the Giant Magellan Telescope (GMT). The country’s Daejeon-based Korea Astronomy and Space Science Institute (KASI) is the ninth partner and represents the second non-US country in the 25-m optical–IR project spearheaded by the Carnegie Institution for Science.
South Korea will contribute about 10% of the estimated $700 million total construction cost; so far $130 million has been committed. One of three huge telescopes in the works globally (see Physics Today, September 2008, page 28 ),the GMT primary mirror will comprise seven 8.4-m-diameter, 20-ton segments. KASI scientists will contribute their expertise in secondary-mirror polishing.
Assuming money is raised, construction is set to start in 2012 and the telescope would see first light at its Las Campanas site in the Andes Mountains of Chile in 2019.
