About

The US Extremely Large Telescope Program (US-ELTP) will provide US-based astronomers with nationally funded all-sky observing access to two of the world’s most powerful telescopes, the Giant Magellan Telescope and the Thirty Meter Telescope. NSF's NOIRLab will facilitate an open peer-review process of observing proposals, archive all data from both observatories, and provide an extensive suite of user support and data analysis services.
