WebMAVEN. Planets can lose water and CO 2 above their surfaces in two ways. The Sun and its solar wind can strip water vapor and gaseous CO 2 from the top of the atmosphere … WebJeans’ escape applies when a gas evaporates molecule by molecule from an exobase. But if conditions favor faster escape, the air flows into the vacuum of space, pushed along by pressure from below. This can occur if the bulk gas in the upper atmosphere is a good absorber of ultraviolet light and the heated air flows en masse.

WebSep 2, 2015 · During its periodic "deep dip" campaigns, MAVEN lowers its closest approach to only 125 km above Mars, dipping into the upper atmosphere to measure it in situ. When water molecules are split apart in the Martian atmosphere, the resulting hydrogen atoms escape more easily from the planet than the heavier oxygen atoms. WebMar 31, 2024 · Gases are being lost from the Mars atmosphere to space today [e.g., (1, 2)], potentially in quantities sufficient to change the planet’s climate [e.g., ()].
