Abstract
The proposed US Extremely Large Telescope (ELT) Program would secure national open access to at least 25% of the observing time on the Thirty Meter Telescope in the north and the Giant Magellan Telescope in the south. ELTs would advance solar system science via exceptional angular resolution, sensitivity, and advanced instrumentation. ELT contributions would include the study of interstellar objects, giant planet systems and ocean worlds, the formation of the solar system traced through small objects in the asteroid and Kuiper belts, and the active support of planetary missions. We recommend that (1) the US ELT Program be listed as critical infrastructure for solar system science, that (2) some support from NASA be provided to ensure mission support capabilities, and that (3) the US ELT Program expand solar-system community participation in development, planning, and operations.
Highlights
Over the last 25 years, a generation of 8m-class optical-infrared telescopes has allowed us to study faint objects from the outer reaches of our solar system to the first billion years of cosmic history
The proposed federal investment would maximize the scientific return from a cooperative, national US Extremely Large Telescope (ELT) Program
The angular resolution of ELTs operating with adaptive optics, as well as their sensitivity, will enable transformational new research on objects throughout the solar system
