We all know how beautiful our Earth is with those oceans, lakes and running rivers, but another planet used to be just like that. Mars used to be wet, and that can be observed in the ancient shorelines, dried up riverbeds and winding canyons that are all over the Red Giant. However, that period has ended, and now Mars can no longer be inhabited as people would die from the deadly space radiation of which we are protected on Earth by the magnetosphere, and we could not survive anyway because of the too-thin atmosphere.
What happened to all that water that was previously on Mars?
NASA scientists have thought about this for a while now, and you can read all their conclusions in the journal Nature where their new study has been published on 10th of April. The water might have disappeared because of giant dust storms that are regular events on Mars and have such an intensity that even the telescopes scientists use on Earth can see them. The duration of such a martian storm might be extended over weeks, and they are so long they could cover continents.
The Red Planet is suffering annually of at least one storm like that, according to NASA scientists. N the summer of 2018 one such storm has also caused the heartbreaking death of the Opportunity rover from NASA that has served America for years.
Are dust storms to blame?
A planetary scientist at NASA’s Goddard Space Flight Center, Geronimo Villanueva, said that we might get an explanation from the global dust storm as he finds them the cue to solving this issue: “ Where went all the water from Mars?” He claims that the water vapor was lifted up by the dust storms and because the altitude was too high, the natural water cycle would have gotten disrupted and this way the water could not come back as rain.
Karen and her husband live on a plot of land in British Columbia. They aim to grow and raise a significant part of their food by maintaining a vegetable garden, keeping a flock of backyard chickens and foraging. They are also currently planning a move to a small cabin they hand built. Karen’s academic background in nutrition made her care deeply about real food and seek ways to obtain it. Thus sprung Anna’s interest in backyard gardening, chicken and goat keeping, recycling and self-sufficiency.
