Planetary researcher Erdal Yiğit, with George Mason University, has published a Perspective piece in the journal Science proposing that upper atmospheric interactions with solar wind can’t completely clarify the deficiency of surface water on Mars. In his paper, he recommends three other major factors should be thought about also: gravity waves, convection and dust storms.
Planetary researchers by and large concur that there used to be a great deal of water on the surface of Mars, and they additionally concur that the surface water was gradually lost to space as hydrogen throughout billions of years. Earlier research has recommended that water molecules were destroyed by sunlight in the lower Martian atmosphere, bringing about the hydrogen from the water floating off into space. In his paper, Yiğit proposes that there is as yet lacking proof to recommend that the water misfortune was so clear.
He proposes that there were different factors impacting everything too, noticing that new experiments have shown that water in the Martian atmosphere might have been carried straightforwardly into the upper atmosphere, where it would have been destroyed prior to drifting into space. This new proof proposes things probably been going on in the lower environment to drive the water into the upper atmosphere. Yiğit proposes it might have been a blend of things, for example, low height convection currents, dust tempests or gravity waves.
Yiğit starts his contention by noticing that new proof from Mars probes shows that water is as yet getting away into space—and that it happens for the most part during the Mars summer, when the planet likewise experiences global dust storms. He further proposes that such dust tempests might have played a role in circulating hydrogen after it was parted from oxygen molecules by solar radiation. He says that it shows up probable that upward-propagating gravity waves might have played a role in pushing water up.
Yiğit proposes that the deficiency of surface water on Mars can’t be completely clarified without thinking about factors in both the upper and lower atmosphere and the upward coupling that probably happened between the two.
