All our science buffs might remember the Martian sandstorm of 2018. The storm also gave us an unknown gas that wasn’t detected before in the planet’s atmosphere. For the first time in history, the ExoMars orbiter sampled traces of hydrogen chloride, consist of chlorine and a hydrogen atom. This discovery gave Mars scientists a new mystery: how the gas got there? And we all are eager to know the answer to this mystery.
“For the first time we discovered hydrogen chloride on Mars,” said Kevin Olsen, a physicist of the University of Oxford in the UK. This is the main recognition of halogen gas in the atmosphere of Mars, and addresses another compound cycle to comprehend.”
Since the scientist confirms the volcanic activity in Mars they’ve been keeping an eye on the gases that contain chlorine in the mars atmosphere. Although if hydrogen chloride is produced by volcanic activity then it should only spike regionally and can co-exist with other volcanic gases.
But the hydrogen chloride detected by the EcoMars did not show such signs. It was detected in both the northern southern hemisphere of Mars during the hey great Martian sandstorm of 2018 hey and the absence of other volcanic gases was obtrusive. This points out that the hydrogen chloride gas was being produced by some other procedure. Fortunately here on earth, we have a similar process which will help the scientist to understand what it could be.
Olsen said “To free chlorine you need water vapor and to form hydrogen chloride by-products of water is essential. Water is critical in this chemistry”
“We likewise notice a correlation to dust: we see more hydrogen chloride when dust action increase, a cycle connected to the occasional warming of the southern side of the equator.”
For the moment, Laboratory research analyses, modeling, and assumptions will help researchers preclude or verify likely mechanisms behind the break of hydrogen chloride in the Martian environment. The study has been published in Science Advances.
