Could Mars have been the first planet in our solar system to support life? New research suggests it’s possible. Recently, EarthSky reported on a study showing that Mars was once likely a water world.

And the new study goes a bit further, suggesting that icy asteroids brought enough water to early Mars for a global ocean at least 980 feet (300 meters) deep (or deeper in some places). If so, those same asteroids might have brought organic molecules needed for life to begin on a young Mars.
