Scientists have reported the first evidence of the presence of solitary waves or distinct electric field fluctuations in the Mars magnetosphere. The study of these waves is crucial as they directly control particle energisation, plasma loss, transport etc. through wave-particle interactions. Scientists Report First Evidence of Solitary Waves in Mars’ Magnetosphere; Discovery May Decode Mystery Behind Ion Loss.

If Mars s water escaped into space through the atmosphere, the researchers would expect to find a very specific ratio of hydrogen to deuterium.
Instead, their findings suggest the planet s water was lost through atmospheric escape as well as being locked up in the crust.
On Earth, water that seeps into the crust forms mineral with water in their structure.
The minerals are melted down and the water works its way back into the atmosphere through plate tectonics and volcanism.

Mars, however, does not have any plate tectonics so when the planet dried up, the drying was permanent.
