So the answer is 17,100 km, or about half the altitude required for earth (35,700 km).
And Deimos orbits at...
>Semi-major axis 23,460 kilometres (14,580 mi)

So yeah, only Phobos to worry about, even with a counterweight.

You can smash Venus gladly, we need that thick atmosphere gone.
It won't cost billions upon billions in building in maintenance as it would completely use automation and asteroid mining in order to create such colossal superstructures.

But but but I don't want to leave Mars yet ;_;

We're the kind of species that needs a frontier — for fundamental biological reasons.
There is a new world next door. And we know how to get there.

>A sky with two suns is a favourite image for science fiction films, but how would a binary star system affect life evolving on an orbiting planet? Jack O'Malley-James of the University of St Andrews has studied what plants might be like on an Earth-like planet with two or three suns and found that they may appear black or grey.

>NASA's Mars Reconnaissance Orbiter has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet's axis varies. This process can affect the stability of liquid water, if it exists on the Martian surface, and increase the frequency and severity of Martian dust storms.
