Terraformed Mars from human base on Phobos by David A. Hardy

In 1994 the famous British space artist David A. Hardy created several retrofuturistic illustrations of a human base on Phobos, the closest of two natural Martian moons, in front of a terraformed Mars.

Mars Base Alpha in a crater by Anastasia Volyk & Vladyslav Lysenko

Ukrainian 3D artists Anastasia Volyk and Vladyslav Lysenko have created a concept for SpaceX's Mars Base Alpha in a small Martian crater.

In the further future hyperloop lines could connect Mars Base Alpha with other human colonies on Mars. I would place Starship launch pads outside the crater.
