Mars Ain't the Kind of Place to Raise Your Kids

Sad:

The Mars rover Curiosity is doing more than channeling its inner tourist and snapping photos every chance it gets. Two new papers appearing in this week's issue of Science are the first to come out of the Mars Science Laboratory that talk about the planet's surface. Both papers say that Mars has been steadily losing its atmosphere over the past 4 billion years.

We'd better hurry, while there's still enough left for terraforming.
