Abstract
The hybrid integration of ground-based telescopes with space-based optical components has the potential for unprecedented observational precision, opening new horizons for scientific discoveries in astronomy. We focus on the first hybrid ground-space observatory dedicated to the search for life beyond Earth-a top scientific priority in modern astronomy. In this talk, we present, on behalf of the KISS team, the findings of our recent study supported by the Caltech KISS program, which outlines a clear implementation plan, mission architecture and workflow for designing and deploying a shared 99 m orbiting starshade to work with large ground-based telescopes equipped with adaptive optics (AO) such as the 39 m ELT, 30 m TMT, 24 m GMT, and 10 m Keck to directly image the first Earth-like planet around a Sun-like star. This approach provides high-contrast imaging and high-resolution spectroscopy, enabling the search for potential biosignatures such as oxygen and water.

As a NASA postdoc and later civil servant at Goddard Space Flight Center, Mather conceived the COBE (Cosmic Background Explorer) and led the team beginning in 1974, leading to launch in 1989 and a Nobel prize in 2006 (physics), for the first precise measurements of the spectrum and anisotropy of the cosmic microwave background radiation. As the senior project scientist for the James Webb Space Telescope (1995-2023) he led the science teams and worked with engineers and managers to make the world’s most powerful telescope. With Webster Cash, he proposed a starshade to work with the JWST. Since 2018, he has led studies of the HOEE, building teams, and finding innovative solutions to technical challenges. Mather received his BA (highest honors, physics, 1968) at Swarthmore College, and his PhD (physics) at the University of California, Berkeley (1974).
