On Mars, deep-water diversity has stood the test of time, meteorites show


The water buried deep within Mars likely came from at least two very different sources long ago, a new study suggests.

“These two different sources of water in Mars’ interior might be telling us something about the kinds of objects that were available to coalesce into the inner, rocky planets,” Jessica Barnes, an assistant professor of planetary sciences in the University of Arizona Lunar and Planetary Laboratory, said in a statement.

“This context is also important for understanding the past habitability and astrobiology of Mars,” Barnes added.
