volcanic activity may still be taking place on Mars. In a
paper published in Thursday's issue of the journal Nature,
planetary scientists said high-resolution stereo images
taken by the orbiter revealed lava flows without any
evidence of impact craters. The lack of craters implies that
the flows must be very young, likely no more than about two
million years old. Scientists believe that volcanic
activity, once thought to have died out hundreds of millions
or even billions of years ago, may still be possible on the
planet today, taken place during very brief, intermittent
periods. The Mars Express images also reveal evidence of
glacial activity within the last few million years on the
slopes of Olympus Mons, the planet's tallest mountain.
