While Mars' surface is considered to have become cryogenic ~3.7 Ga, stable subsurface aquifers persisted long after this transition. Their extensive collapse triggered megafloods ~3.4 Ga, and the resulting outflow channel excavation generated voluminous sediment eroded from the highlands. These materials...
One of the biggest: What’s the most practical way to power future Mars colonies? The seemingly simple question took UC Berkeley engineering students Anthony Abel and Aaron Berliner four years of hard work to figure out. In findings published last week in Frontiers in Astronomy and Space Science...

In light of these aspects, our research group was naturally led to one key question: could the same life-generating events that occurred on Earth have also happened on Mars? A portrait of Mars from four billion years ago We set out to answer this question using three models, which culminate...
While the cold, dry surface of Mars, with itsharsh radiation environment, is widely considered to be uninhabitable, the subsurface has been hypothesized to be a viable, long-lived habitable environment, protected from the punishing surface conditions of Mars and a place where water could be stable...
