Mars has water on its surface, and it’s in liquid form at least some of the time.
NASA on Monday announced the results of a new study showing that salty liquid water flows seasonally on Mars, giving the red planet one of the essential ingredients for life.

Discovering life on another planet, only to contaminate that world with our own pesky microbes, is one of NASA’s nightmare scenarios. To find out whether single-celled Earthlings can hitchhike to Mars and survive on the Red Planet’s surface, NASA is going to see how they like it 120,000 feet up.

Our bodies aren’t meant for space. We require too much maintenance to speed through the stars. We need a steady supply of things absent from space — namely water, food and oxygen. We crave warmth but won’t find it in deep space, where the average temperature is -455 degrees Fahrenheit. Even if we could survive in an icy vacuum without sustenance, we’d probably go insane without distractions and room to move.

For more than century, humans have imagined building colonies on Mars, and now settling the Red Planet is no longer a pipe dream—it’s something we might achieve in little over a decade. And many people, including the author of the new book How We’ll Live on Mars, believe our very survival as a species hinges on it.

At the end of another long day examining rocks on Mars, Curiosity stopped for a moment to watch the sun go down — the first time in 956 sunsets that the rover has watched it in color.

Deep-space radiation is a serious but largely unquantified threat to astronauts making a long trip to Mars. A new study in mice is discouraging: Space-like levels of radiation exposure damaged their neurons, giving the mice cognitive problems.
