Martian Caves Discovered

FLAGSTAFF, Ariz., Sept. 24 (UPI) -- NASA spacecraft have detected entrances to seven possible caves near a Martian volcano, increasing interest in that planet's possible underground habitats.

Very dark, nearly circular features as large as 820 feet in diameter puzzled researchers who found them in images taken by the National Aeronautics and Space Administration's Mars Odyssey and Mars Global Surveyor orbiters. Using infrared imaging, NASA scientists concluded the circular features might be openings to cavernous spaces beneath the planet's service.

"They are cooler than the surrounding surface in the day and warmer at night," said Glen Cushing of Northern Arizona University and a member of the U.S. Geological Survey's Astrogeology Team. "Their thermal behavior is not as steady as large caves on Earth that often maintain a fairly constant temperature, but it is consistent with these being deep holes in the ground."

A report of the discovery of the possible cave skylights by Cushing and his colleagues was published online recently by the journal Geophysical Research

This was first published a while back (a couple months?). I wish we knew more by now!

So that is where the little buggers are hiding.

The information goes back to mid March of this year. Would be nice to get further reports.

While the news is a bit dated, I don't recall any threads on it.

I do find that strange given the fascinating aspect of the information.

John Carter is investigating.

can't we use some sort of sonic sensor (the kind used for oceanography) next time a craft goes to Mars to tell if there are lifeforms? Or does it work poorly through ground?
