Turns Out NASA Creates Posters For Every Space Mission And They’re Hilariously Awkward
Out of curiosity, presumably at some point the Moon will leave our orbit and become just another rock in our solar system, be it's own orbit around the sun or it'll just drift off into the abyss.
We've got ~500 million years to colonise and terraform the Moon then?Apparently not. Though the Moon is currently receding, this will stop in about 50 billion years. And in this more “stable” configuration, both the rotation of the Earth and the orbit of the Moon will take 47 days. Meaning: only one side of the Earth will ever see the Moon, and ocean tides will be “frozen” in place.
At least… that’s what could happen theoretically.
Long before then, most life will be dead (due to the cessation of photosynthesis - ~500 million years from now); and the Sun will expand and consume the Earth (~5 billion years from now).
IOW, certain other issues will present themselves before we have to worry about the Moon being too far way.

Thank You for the reply. I had assumed it would just drift off, though instead, it'll have burnt up - along with Earth long before it even attempts it's great escape.
It's scary, isn't it? To think how much life has preceded humanity, and yet here we are, ultimately still in our infancy. I don't think a lot of people quite comprehend just how long ago the Jurassic, Triassic and Cretaceous (and before) periods actually were.
And then you watch a video of Trump and begin to question said ingenuity.

HubbleSite: News - Young Planets Orbiting Red Dwarfs May Lack Ingredients for Life
As part of their natural (and volatile) formation, red dwarf star systems may blast away their supply of water. This means that Earth-sized planets in such systems (even if they’re in the “Goldilocks zone”) could be dry and lifeless.
As it happens, red dwarfs make up about three-quarters of all the stars in the Milky Way. So the hypothetical estimates for extraterrestrial life may have to be drastically reduced.
This is a variation of the “cosmic calendar” made famous by Carl Sagan. But in that model, the age of the entire Universe - rather than the age of the Earth - is compressed into a calendar year. As such, the dates and times of milestones are shifted slightly (as per the difference between 13.8 and 4.5 billion years).
Overlooked (or simply irrelevant) to so many people. It truly is astonishing when you think about it - and frightening too. In all that time, we're the only (known) species to have developed a sense of sentience in not only life on Earth, but (as we know it) life in the entire universe. Not that I believe we're alone in the universe for one minute, but when you factor things like this in, and the time scale of it, it truly does make you wonder what else is out there, or more specifically, what could have been a long, long time ago - and what may still come.
