Marsquakes, Add Water and Shake
An anonymous reader writes "Analysis of Mars orbital data shows northern pit chains as evidence for relatively recent seismic activity. If marsquakes release water-ice to the surface, then such young features may be reshaping and eroding the landscape from below. No modern volcanic or seismic activity has ever been confirmed before. A long-standing mystery is why the northern hemisphere is smooth, while the martian south is so rugged."
There's only one comment so far. That means nobody is reading this story. This looks like the perfect hiding place for those missle-launch codes. --Alpha--Delta--589--Charlie-- Ha ha!
