Laboratory evidence is challenging theories that Mars’ ruddy surface came from a past when the planet was awash with water, New Scientist said.
Defenders of this hypothesis say Mars’ reddish dust came from iron in rocks that over billions of years dissolved into the planet’s oceans, lakes and rivers.
When will we start to judge planets based not on the color of their surface but on their character alone. Red planet, big blue ball, enough is enough.
Can’t we all just get along? 😉
One wonders then why our moon is not also red as it has been a popular final resting place for for meterites going on 4.5 billion years.
