There is also evidence of flooding that occurred less than several million years ago, most likely as the result of the release of water from aquifers deep underground or the melting of ice. Although recent study has suggested that Mars may have initially had a substantial atmosphere, largely of...
In the next 20-40 million years Mars’ largest moon Phobos will be torn apart by gravitational forces leading to the creation of a ring that could last up to 100 million years. Sunsets on Mars are blue. During the martian day the sky is pinkish-red, this is the opposite of the Earth...
Scientists have no direct evidence for recent or ongoing eruptions, but if these volcanoes were active as recently as 100 million years ago (an estimate of the time of last eruption based on the extent of impact cratering on their slopes), some of them may still be at least intermittently ...

In the 1960s, humans set out to discover what the red planet has to teach us. Now, NASA is hoping to land the first humans on Mars by the 2030s.
These features are probably quite young, formed 1.5 to 200 million years ago in Mars’ late Amazonian period when the planet was volcanically active. The team’s paper presented at the 2012 Lunar and Planetary Science Conference
Recently, SpaceX founderElon Muskmade some interesting comments on Earth Day 2021. A casual and barefoot Musk spoke with Peter Diamandis, who is launching a competition with a $100 million prize. TheXPRIZE Carbon Removal competitionis the largest incentive prize in history to tackle the biggest ...
