What Would Life Be Like On Deimos?
Let’s all just assume that Deimos, the smallest moon of Mars, is capable of sustaining life, instead of being the lifeless rock that it is today, and that on the moon of Deimos is a population of living organisms not too different from humans, in fact let’s assume they are exactly the same as humans. What would life be like for them?
First off, they would have significantly less muscle mass, since the gravity of Deimos is 0.0003 meters per seconds squared, compared to Earth’s 9.8 meters per seconds squared, and as such they would weigh much less, requiring significantly less muscle in order to move the same amount of body mass.
If you chose to walk all the way around Deimos, you could probably do it in about 10 hours, since its mean circumference is about 24.2 miles, and the average human walking speed is 2.5 mph. In addition, if you had a car, you could drive all the way around the world in a little under half an hour, assuming you traveled at 60 mph. Visiting the in-laws has never been easier.
However driving at 60 miles per hour around Deimos would be absolutely silly, since the escape velocity of Deimos is 5.6 m/s. The maximum speed limit of Deimos would have to be about 12mph, since if you traveled any faster than that you would essentially turn your car into a rocket.
In fact while we’re setting speed limits, we’d have to make jumping illegal as well, since one good jump would put you in orbit. In fact we’d probably be reading obituaries and missing people reports every day about that sort of thing, something along the lines of “Jacob decided to go on his morning run, and was last seen in the sky heading towards Mars”. There would probably be public service announcements every day, like “ENTERING ORBIT: IT COULD HAPPEN TO YOU”. It also wouldn’t be too uncommon for Martians to see humans falling from the sky down onto Mars.
Overall, life on Deimos would be rather silly and I would not recommend it.
