Building the Giant Magellan Telescope with Dr. Rebecca Bernstein and Dr. Jim Fanson
The Giant Magellan Telescope will be a member of the next generation of extremely large ground-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed in the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2029. The GMT has a unique design that offers several advantages. It is a segmented mirror telescope that employs seven of today’s largest stiff monolith mirrors as segments. Six off-axis 8.4 meter or 27-foot segments surround a central on-axis segment, forming a single optical surface 24.5 meters, or 80 feet, in diameter with a total collecting area of 368 square meters. The GMT will have a resolving power 10 times greater than the Hubble Space Telescope. The GMT project is the work of a distinguished international consortium of leading universities and science institutions. Link:

The Giant Magellan Telescope: 10x The Power of the Hubble
The Giant Magellan Telescope is an extremely large land-based telescope that has been under construction since 2015. When completed, the telescope will be the seventh large telescope on the planet. The telescope will consist of seven 27 feet diameter primary segments that will be able to observe near-infrared and optical light. These segments will have the resolving power of an 80.4 ft primary mirror and collecting area equivalent to a 72.2 ft one. This means that the Telescope is expected to have a resolving power that is at least ten times greater than that of the Hubble telescope. You may think telescopes can be located anywhere with a clear view of the sky. But it's way more complicated than that. For a telescope, especially an extremely large one, to have a good view of the sky, it needs to be placed at an altitude of about 2000 meters above sea level.

Ingersoll to build the megastructure for the Giant Magellan Telescope
Ingersoll Machine Tools will play a critical role in the construction of the Giant Magellan Telescope, which will help scientists explore the frontiers of the universe and seek forms of life beyond our solar system. Magellan will measure 80 feet in diameter and is billed as a next-generation giant optical infrared observatory capable of changing the history of space exploration. Rockford-based Ingersoll and MT Mechatronics of Mainz, Germany, will partner to design and manufacture the 1,800-ton precision mechanism known as the “telescope structure” that holds the Magellan’s optics. The telescope will be designed by MT Mechatronics and manufactured, assembled and tested by Ingersoll before it is installed at an observatory high in the remote Andes Mountains of Chile in 2025. “We selected Ingersoll Machine Tools and MT Mechatronics for their commitment to quality, extensive experience with astronomical telescopes and abilities to manufacture complex precision structures,” Giant Magellan Telescope Organization Project Manager Dr. James Fanson said in a news release. The nine-year contract for the telescope structure is valued at $135 million. The structure of the telescope will hold seven giant mirrors in position as they bring the light of distant stars and galaxies into focus so they can be analyzed by the scientific instrumentation built into the huge device. The structure of the telescope, complete with mirrors and instrumentation, will weigh 2,100 tons. “It will be a special day when the Giant Magellan Telescope structure is completed and placed in service in Chile, as part of one of the most complicated and fascinating projects that the world scientific community has ever undertaken,” Ingersoll Machine Tools CEO Chip Storie said. Ingersoll Machine Tools develops advanced machine tools for the aerospace, transportation, energy and other industries. The company has about 200 employees. Ingersoll International, the forerunner of Ingersoll Machine Tools, was founded in 1891 and employed about 2,000 during its heyday in the 1960s and ’70s. Ingersoll International went bankrupt in 2003 before the company was purchased by the Camozzi Group of Italy.

Computational Fluid Dynamics simulation of GMT enclosure
This video is a simulation of the GMT enclosure and the air flow through it. These lines are not precisely the airflow however: technically they are the "magnitude of the spatial gradient of the refractive index of air on a plane parallel to the wind and aligned with the enclosure symmetry axis". What this means in practice is this simulation shows the regions of optical turbulence – or random variations in air speed and temperature – that can affect the image quality of the telescope. We run simulations like this with various orientations of the telescope relative to the wind and for different environmental conditions such as temperature and wind speed. We analyze all this information to understand which aspects of the design of the enclosure negatively affect image quality, and what can be done about it. As the design of the enclosure moves into its final stages these kinds of simulations are important to ensure our design guarantees the best possible image quality from the telescope.
