Mars, a Post-Habitable Planet?
Matteo Crismani, Richard Cartwright, Michael Chaffin +3
Mars provides a critical analog to once habitable exoplanets that have since lost their surface liquid water. The current atmospheric state of Mars retains the chemical fingerprint…
Nonthermal hydrogen loss at Mars: Contributions of photochemical mechanisms to escape and identification of key processes
Bethan S. Gregory, Michael S. Chaffin, Rodney D. Elliott +3
Hydrogen loss to space is a key control on the evolution of the Martian atmosphere and the desiccation of the red planet. Thermal escape is thought to be the dominant loss process,…
Fully coupled photochemistry of the deuterated ionosphere of Mars and its effects on escape of H and D
Eryn M. Cangi, Michael S. Chaffin, Roger V. Yelle +2
Although deuterium (D) on Mars has received substantial attention, the deuterated ionosphere remains relatively unstudied. This means that we also know very little about non-therma…
Higher Martian atmospheric temperatures at all altitudes increase the D/H fractionation factor and water loss
Eryn M. Cangi, Michael S. Chaffin, Justin Deighan
Much of the water that once flowed on the surface of Mars was lost to space long ago, and the total amount lost remains unknown. Clues to the amount lost can be found by studying h…
