FAYETTEVILLE, Ark. -- A team of researchers from
the University of Arkansas has measured water evaporation
rates under Mars-like conditions, and their findings favor
the presence of surface water on the planet. Water on the
planet's surface makes the existence of past or present life
on Mars a little more likely, according to the group.

The researchers have brought on-line a large planetary
environmental chamber in which temperature, pressure,
atmosphere, sunlight and soil conditions can be reproduced.

I take it that gravity on Mars being a mere 38% of that in the
experiment has little bearing on the evaporation rate?
