NASA | El Océano Antiguo de Marte

NASA researchers have measured the proportion of heavy water on Mars, revealing that at least 20% of the planet was once covered by water. Over time, nearly 90% of this water was lost to space, with the remainder stored in the polar caps. These findings suggest Mars was wetter than previously thought, potentially improving its habitability prospects.
