pasadena calif the giant magellan telescope organization (gmto) along with its international partners including texas a&m university today announced the start of hard rock excavation for the giant magellan telescopes massive concrete pier and the foundations for the telescopes enclosure on its site at las campanas observatory in chile artists rendering of an aerial view showing the giant magellan telescope and support facilities at las campanas observatory chile high in the andes mountains (credit: giant magellan telescope – gmto corporation) the excavation work which uses a combination of hydraulic drilling and hammering and is expected to take about five months to complete will be performed by miner&iacutea y montajes conpax (known as conpax) a construction services company that has previously performed site work for other observatories in chile excavation is a key step toward the construction of the gmt which is expected to see first light as early as 2024 the 25-meter diameter gmt expected to have a final weight of about 1 600 metric tons will comprise seven 84-meter mirrors supported by a steel telescope structure that will be seated on the concrete pier it will be housed inside a rotating enclosure that will measure 65 meters (~22 stories) tall and 56 meters wide as well as working on the enclosure and telescope pier foundations conpax will excavate a recess in the summit rock for the lower portion of the mirror coating chamber and foundations for a utility building and tunnel on the summit with the start of construction of the permanent buildings on the site the gmt is showing tangible progress toward completion said gmto project manager james fanson we are delighted that conpax is carrying out this important work the most challenging part of their work on the summit will be to excavate the solid rock of the mountain top to a depth of 7 meters (23 feet) to hold the concrete for the telescope pier much of this work will be done with a hydraulic rock hammer and jack hammer to ensure that the integrity of the solid bedrock below the pier is undamaged artists rendering of the giant magellan telescope reflecting the chilean sunset for more images visit giant magellan telescope gallery in total we expect to remove 5 000 cubic meters or 13 300 tons of rock from the mountain and will need 330 dump-truck loads to remove it from the summit fanson said las campanas observatory located in the southern atacama desert of chile and owned by the carnegie institution for science is one of the worlds premier astronomical sites known for its clear dark skies and stable airflow that produces exceptionally sharp images with its unique design the gmt will produce images that are 10 times sharper than those from the hubble space telescope in the infrared region of the spectrum and will be used by astronomers to study planets around other stars and to look back to the time when the first galaxies formed in the past year the gmt project has cast the fifth primary mirror segment at the university of arizonas richard f caris mirror laboratory announced a new partner for the project in arizona state university and awarded design-build contracts for the telescope mount #
