KMTNet is relevant here, because- even though the Korea Microlensing Telescope Network is primarily an exoplanet search program, it’s still a wide-field, high-cadence sky sweep. It’s no coincidence that the program gathers asteroids/comets as an everynight coproduct. The Korean program is a valued complement to the rest of the world’s sky search efforts, and it’s great to see the telescopes are on the job. We await the Korean community’s second-generation telescope, NSOS-α (Near Space Optical Survey-α).
Süli Forgács-Dajka 2024 is EXTREMELY relevant, because the full title continues: “and its role in the origin of terrestrial water.” The authors find that, even after collisions, the debris from Ceres-like objects in the asteroid belt is sufficient to bring water to Earth. Plenty of water.
