On the possible presence of ice on the moon
Web31 de mai. de 2024 · Another tantalizing question is how old the moon’s ice is. If the water was delivered by icy comets or asteroids, it could be as ancient as the solar system and could mark the early delivery of water to Earth and the moon. But if the water was produced by chemical reactions driven by the solar wind, it is much more recent. Or both may be true. Web20 de ago. de 2024 · In the darkest and coldest parts of its polar regions, a team of scientists has directly observed definitive evidence of water ice on the Moon’s surface. These ice deposits are patchily distributed and could possibly be ancient. At the southern pole, most of the ice is concentrated at lunar craters, while the northern pole’s ice ...
