Experiments carried out in the OU Mars Simulation Chamber — specialised equipment, which is able to simulate the atmospheric conditions on Mars — reveal that Mars» thin atmosphere (about 7 mbar — compared to 1,000 mbar on Earth) combined with periods of relatively warm surface temperatures causes water flowing on the surface to violently boil.

Here is what scientists think is happening: when Ceres swings through the part of its orbit that is closer to the sun, a portion of its icy surface becomes warm enough to cause water vapor to escape in plumes at a rate of about 6 kilograms (13 pounds) per second.
