In 2026, Airi Toida and Yuichiro Ezoe modeled a sub-10-kilogram X-ray telescope that could spend two years tracing oxygen, iron, magnesium, aluminum, and silicon across the Moon, toward the complete elemental map Apollo never delivered

A sub-10-kilogram X-ray telescope modeled by researchers at Tokyo Metropolitan University could map oxygen, iron, magnesium, aluminum, and silicon across the entire lunar surface in about two years, if it ever flies on a small satellite around the Moon. The instrument is not a booked mission yet. It is a mission concept built from simulations, [...] The post In 2026, Airi Toida and Yuichiro Ezoe modeled a sub-10-kilogram X-ray telescope that could spend two years tracing oxygen, iron, magnesium,
