Model explains how life may have emerged on Mars
Harvard researchers have solved a decades-old mystery about how the early Martian atmosphere and climate may have evolved to support periods of warmth and running water on the planet.

A way to make Mars habitable
Researchers from Harvard University, NASA’s Jet Propulsion Lab, and the University of Edinburgh suggest that regions of the Martian surface could be made habitable with a material — silica aerogel — that would mimic Earth’s atmospheric greenhouse effect.

A watery Mars, a changed outlook
One of the lessons from this week’s announcement of liquid water on Mars is that the Red Planet is a much more diverse place than previously thought, one that holds a multitude of niche environments that might be more hospitable to life than average planetary conditions might indicate, said Professor Robin Wordsworth.

Unveiling the ancient climate of Mars
The high seas of Mars may never have existed. According to a new study that looks at two opposite climate scenarios of early Mars, a cold and icy planet billions of years ago better explains water drainage and erosion features seen today.

Mars rover, slightly used, runs fine
Originally scheduled to operate on the Red Planet’s surface for 90 Martian days, the rover Opportunity has now logged more than 3,500 days, traveled nearly 39 kilometers, and collected a trove of data that scientists have used to study the planet’s early history, particularly any past traces of water.

Mars’ water appears to have been too salty to support life
A new analysis of the Martian rock that gave hints of water on the Red Planet — and, therefore, optimism about the prospect of life — now suggests the water was more likely a thick brine, far too salty to support life as we know it. The finding, by scientists at Harvard University and Stony…

Oceans are back on Mars
Since spacecraft sent back the first close-up images of Mars more than 30 years ago, some experts have insisted that oceans once existed on the now dry, cold planet. Critics have maintained for decades that such an idea is the product of unrestrained imaginations. Now, a study published in today’s (June 14) issue of the…
