Transport of Water In A Transient, Impact
A new study using the PLANET DSMC code analyzes how comet impacts deliver water to Mercury's polar cold traps. The research quantifies the atmospheric evolution of water plumes and finds that Mercury is significantly more efficient at trapping impact-delivered water than the Moon.
Why it matters
Understanding water delivery mechanisms on Mercury provides critical insights into the geological and atmospheric history of inner solar system bodies.
Mercury s polar cold traps host water ice deposits that are likely populated with impact-delivered water via Mercury s exosphere.
