NASA spacecraft finds possible Mars caves



WASHINGTON (Reuters) - An orbiting spacecraft has found evidence of what look like seven caves on the slopes of a Martian volcano, the space agency NASA said on Friday.

The Mars Odyssey spacecraft has sent back images of very dark, nearly circular features that appear to be openings to underground spaces.

“They are cooler than the surrounding surface in the day and warmer at night,” said Glen Cushing of the U.S. Geological Survey’s Astrogeology Team and Northern Arizona University.
