CU Boulder scientists might have found as to how Mars got all of its clouds: just include meteors. Astronauts have long seen clouds in the middle atmosphere of Mars, which starts almost 18 Miles (almost 30 Kilometers) on top of the surface but have grappled to clarify how they are created.
Now, new research, which will be posted in the Nature Geoscience journal, evaluates those wispy accumulations and recommends that they owe their presence to a phenomenon dubbed as “meteoric smoke.” This is nothing but the icy dust generated by space wreckage slamming into the atmosphere of the planet.
The results are a good warning that planets and their patterns for weather are not isolated from the solar systems surrounding them.
“We are used to thinking of Mars, Earth, and other worlds as actually self-contained planets that decide their own climates,” claimed the lead author of the study and a graduate student in the ATOC (Department of Atmospheric and Ocean Sciences), Victoria Hartwick, to the media in an interview. “But climate is not reliable on the solar system surrounding them.”
On a related note, newly found layers of ice covered a mile below the north pole of Mars are the remainders of old polar ice sheets and can be one of the biggest water reservoirs on the Red Plant, as per researchers at the University of Arizona and The University of Texas at Austin.
The group made the invention with the help of calculations collected by the SHARAD (Shallow Radar) on MRO (Mars Reconnaissance Orbiter) of NASA. SHARAD emits radar waves that can infiltrate almost a mile and a half below the Mars’ surface. The results, posted in Geophysical Research Letters, are essential since the layers of ice are a record of earlier climate on Mars in much the similar method that tree rings are a record of earlier climate on our planet.
