So what? Well, if we ever have to go there, then we don’t have to worry about bringing a big waterbottle with us. Yeah, we are nowhere near that point, at least so we don’t need to journey to Mars out of necessity.
Apparently, the proof of liquid water comes from narrow streaks in satellite images during the summer of the planet that lengthen during warm seasons and fade when it gets cold. This was discovered by Lujendra “Luju” Ojha, who is a death metal guitarist as well as a scientist.
There doesn’t really seem to be a clear source for wear the water is coming from, so it is condensing out of the thin Martian atmosphere or rising up from the salty aquifers or underground ice.
Whatever the case, I suppose it would be possible to live on Mars. Yeah, I know that won’t be in my lifetime, but shoot, I saw want to see that.
