Underground oasis in a Martian lava tube

Shane Powers (USA) & Linjie Wang (China) have created a design of an artificial underground oasis in a Martian lava tube for Marstopia international design contest held by Eleven Magazine. Their design named "Below Freezing" won the "honourable mention" award in the contest. Its main feature, besides utilizing natural lava tubes, is a vertical transportation system (surrounded by 3D-printed ice walls) to Mars's surface. Martian lava tubes could become very handy in creating large, radiation-protected spaces for future human colonists on Mars.

SpaceX Mars Base Alpha concept by Sotiris

Here is a concept of SpaceX's early Mars Base Alpha by Twitter user Sotiris. The concept features a pair of crew Starships with Falcon 9 style landing legs, several pressurized Mars Cybertrucks, The Boring Company's tunnel boring machine and 3-level habitation modules derived from used Starship propellant tanks and connected in pairs (a questionable idea, we think).

Total Recall (1990) concept art by Ron Cobb

Australian artist Ron Cobb has done concept art for many famous sci-fi movies, as Star Wars, Alien, Back to the Future and countless other. One of the movies he has worked on is a movie known to all Mars fans - Total Recall (1990), stared by Arnold Schwarzenegger, Rachel Ticotin, Sharon Stone and Michael Ironside and directed by Paul Verhoeven. Here are some historic concept art images created by Ron Cobb for the famous movie:

Short film: honeymoon trip to the Moon with SpaceX Starship

Two brothers from DeepSpaceCourier have created an animated short film of a newly married couple taking their honeymoon trip to the Moon with SpaceX's Starship. The short film starts with the couple boarding Starship Super Heavy at ocean launch platform; Starship is launched to the Moon and after a few days voyage docks to Lunar Gateway; there the couple switches to a Lunar Starship and lands on the surface of the Moon.

Some images from the short film in chronological order:

Earthscrapers (inverted underground skyscrapers) could be perfect for Mars

When building on Mars you need to seriously consider measures to protect the inhabitants from cosmic radiation. You can cover your very first Martian outpost with few meters of regolith or use expensive materials with radiation blocking properties but for larger structures the obvious choice is to build underground. Lava tubes could be a solution but they are not present everywhere on Mars. So most likely you will need to dig your habitats.

One of the building types perfect for Mars could be earthscrapers (or would you call them marsscrapers on Mars?) - inverted underground skyscrapers with large vertical central void (covered with a transparent dome on the surface) for natural lighting. The living and public space is arranged in multiple levels encircling that central void. Here is an example of such structure designed by Fernando Castiñeira, Hernan Goldfarb, Alejandro Ispani, Alex Nelken, Javier Maratea & Malena Verni for 2007 Skyscraper Competition by eVolo.us

Donut cafe on Mars by Natalia Babiy

As Elon Musk has said: colonizing Mars will create "an explosion of entrepreneurial opportunity because Mars will need everything from iron foundries to pizza joints to nightclubs. Mars should really have great bars". Here is a donut cafe on Mars by Ukrainian concept artist Natalia Babiy. More of her art here.
