Spherical underground Mars colony by Michel Lamontagne

One of the weak spots for any domed human colony on Mars would be the enormous pressure difference needed between the higher interior pressure suitable for humans (~ 1 bar) and the near-vacuum exterior pressure of the Martian atmosphere (0.004-0.011 bar). The dome for such a structure should have heavy anchoring deep underground. But there is a much simpler solution - a spherical hermetic structure mostly underground where only the tip of the sphere (visible as a dome) is located above the ground level. Sphere is the strongest geometric shape for containing internal pressure and the structure can be kept in place by the mass put inside the sphere.

Canadian design engineer Michel Lamontagne has created two concept drawings for such a colony where there is only a domed park above the ground level and all the rest of the colony is located below the ground level with a vertical central opening for natural lighting:

The geodesic surface dome is subdivided into small panes for easier replacement and safety:

Valles Marineris compared to USA

Valles Marineris (or Mariner Valleys) canyon system on Mars is one of the largest canyons of the Solar System. It is located along the equator of Mars and stretches for nearly a quarter of the planet's circumference. Valles Marineris is more than 4000 km (2500 mi) long, 200 km (120 mi) wide and up to 7 km (23,000 ft) deep.

Here is an infographic created by NASA comparing Valles Marineris to the territory of Contiguous United States (48 US states without Alaska and Hawaii) for scale:

SpaceX Starship landing on Mars - 4K UHD renders from Elon's Starship update 2022

When SpaceX CEO and lead designer Elon Musk gave his latest Starship update in February 2022, the presentation contained an animation of Starship's mission to Mars with a landing at Mars Base Alpha in the end. Today SpaceX finally gave public access to 4K UHD version of that animation. Here are some images from it.

"For All Mankind" season 4 - concept art for Helios' Mars colony and space transport

In episode 9 of For All Mankind 3rd season Helios' CEO Dev Ayesa presented a vision for company's next generation spaceship, Mars orbital station and colonies on Mars, some of which we will most likely see realized in season 4 of the show which will air this autumn. We obtained high resolution concept images used in Dev's presentation, you can view further ahead.

For All Mankind is an alternate history sci-fi TV series exploring the idea of never ending space race if Soviets would have beaten US in the race for the Moon:

• In season 1, depicting alternate 1969 to 1974, both Soviets and US start building their separate bases near the lunar South pole;
• In season 2, depicting the alternate 1983, both bases have been expanded and the superpowers compete for resources on the Lunar surface;
• In season 3, depicting alternate 1992 to 1995, Soviets and US are joined by a private company Helios and.. North Korea for a four way race to establish the first human base on Mars.

The intention of the show is each season to jump about a decade further into the increasingly diverging reality of the show. The final scene of season 3 hints season 4 will depict alternate 2003 or so.

Exploring Mars with children by Jon Hrubesch

In "Captain Imagine: Tour of the Solar System" (2020) children's book by Karim Elmahmoudi Captain Imagine, a futuristic space explorer, takes young Emily and her brother Simon on a guided tour of our Solar System. The retrofuturistic illustrations for the book were created by American digital painter Jon Hrubesch. Here is one of the illustrations where Captain Imagine and the two children are exploring a Martian canyon.
