NEW EXPERIMENTAL STUDIES OF ICE GRAIN EJECTION BY MASSIVE GAS FLOW, IMPLICATIONS TO COMETS, ENCELADUS, TRITON AND MARS.

Ice grains are ejected whenever gases are flowing from gas-laden amorphous ice upon its warming-up. We elucidated the mechanism of gas trapping when flowing onto a gas-free ice layer. The observations on ice grain ejection from comets, Enceladus, Triton and the Martian South Polar region are explained as well. [ABSTRACT FROM AUTHOR]
