Water on Mars?

Researchers recently analyzed the composition of some meteorites from Mars and found that the water content was very similar to that of Earth’s upper mantle’s water content! The meteorites were made from parts of Mars’ mantle, and the researchers suggest that volcanic eruptions may have brought these pieces of the mantle to the surface of Mars (before they turned into meteorites and hurtled toward Earth, of course). This re-starts the discussion of the possibility that Mars may once have sustained life…but I have a feeling that will continue to go in circles for a little while longer, at least.
