Large Areas of Mars could Sustain Life

Scientists from the Australian National University modeled conditions on Mars on a global scale and found that large regions could be capable of sustaining life – three percent of the planet actually, albeit mostly underground. By comparison, just one percent of Earth's volume, from the central core to the upper atmosphere, is inhabited by some kind of life.

We need some global cooperation to open up this new frontier.  Are there any countries in a cooperative mood these days?

A very nice article on the Khan Academy and how it is a revolution for students and online education.

Note:  If you have a Roku box, it has a Khan Channel.
