All the probes now at Mars were focused on observing the comet.

Hot Times Inside Luna

A new study of Lunar Reconnaissance Orbiter images finds lava may have flowed on the Moon much more recently than previously thought-- perhaps only tens of millions of years ago instead of 3.5 billion.

That would mean the interior of the Moon remained hot and active into recent times, not the dead world we thought we knew.

Building Civilizations

Yesterday marked the 522nd anniversary of Columbus' discovery of the New World, as Europeans dubbed the lands between them and Asia, sailing west.  At the time, this area was home to a wide array of cultures and societies, many if not all of which were linked together by trade.  At least a couple of those may have approached ancient Rome in sophistication and vision.

Unfortunately for them, their technology probably wasn't quite on the level of ancient Rome, which meant they were no match for their European visitors in that regard.  Fewer than 400 years after Columbus-- an eye blink in the history of Earth-- the most powerful industrial nation in the world was in North America, stretching from sea to shining sea.

An awful lot can happen awfully quickly.  Those who argue against expanding into space should keep that in mind.
