Mars atmospheric studies reveal solar wind effects and potential thickening methods

New research provides insights into the atmospheric loss of Mars and potential methods for its enhancement. Scientists from Boston University have discovered that solar winds create massive Kelvin-Helmholtz waves at the boundary between the Martian atmosphere and space. Because Mars lacks a global magnetic field to act as a shield, these waves mix the upper atmosphere and help eject particles into space, contributing to the planet's thinning atmosphere.

In a separate study, researchers from the Space Research Center of the Polish Academy of Sciences (CBK PAN) explored a theoretical method to thicken the Martian atmosphere. The proposal involves redirecting icy trans-Neptunian objects from the Kuiper Belt or the scattered disc toward Mars. These objects could deliver essential substances such as water, gases, and ammonia to increase atmospheric pressure and temperature.

Implementing this plan would be a massive undertaking, requiring the precise redirection of enormous bodies through gradual acceleration over hundreds of years. The study suggests that using a few very large objects would be more effective than numerous smaller ones for creating a sustained atmospheric change.
