- Martian meteorites analysis showed that Mars likely received water from at least two vastly different sources early in its history. The variability the researchers found implies that Mars, unlike Earth and the moon, never had an ocean of magma completely encompassing the planet. https://uanews.arizona.edu/story/martian-mash-meteorites-tell-story-mars-water-history 4 comments space
