The US-Extremely Large Telescope Program

The US Extremely Large Telescope (ELT) Program is a joint endeavor of NSF’s NOIRLab and the organizations building the Thirty Meter Telescope (TMT) and the Giant Magellan Telescope (GMT). The US-ELT Program is a “two telescopes, one system” program on a mission to revolutionize humankind’s understanding of the Universe. Once complete, the TMT and GMT will be among the largest and most powerful ground-based optical/infrared telescopes on Earth. The US-ELT Program will provide the US science community with nationally funded, full-sky observing access and diverse research opportunities.
