Mars (Planet)

Extract....

While Mars may be a desiccated place where water no longer flows, the planet still has glaciers slowly moving across its surface. Previously, it was thought that Martian glaciers were pure ice with a thin cover of rock and dust. But after 20 years of exhaustive research, scientists have concluded that glaciers all over the planet contain more than 80% water ice, meaning they are nearly pure. These findings could alter our understanding of Mars' climate history and have significant implications for future crewed missions dependent on in-situ resource utilization (ISRU)......

Can you make babies in space? Should corporations govern space settlements? What about space war?

Here's a short timelapse movie I made of Mars emerging from behind the Moon after the occultation. Not the best quality, but my setup wasn't great and it was -20C outside. (Look right at the top of the Moon if you aren't seeing it).

Highly recommend. The red planet you can sleep on

First, let me say, I'm an absolute sucker for European style graphic novels. So when I caught On Mars_ at my local shop, I thumbed through it... Yeah, I'm in.

Dystopian future, criminals are used as slave labor to build a colony on Mars. The story follows a new prisoner, sent to Mars for 20 years. As a police officer, she accidentally killed a kid, the daughter of an influential politician.

The prison colony is full of gangs, religious fanatics, and escapees operating in the wild.

Through the three sections, she encounters these multiple groups and struggles to survive. Until someone decides to overthrow the power structure and take over everything for themselves.

It's honestly, a GREAT read, I had no problem with it at all until the last few pages.

Consider the following tech tree.

• The rocket can double as a living habitat, if it manages to land in one piece. Martian dirt could be used to re-inforce the walls to protect against radiation.

• Solar energy with a battery or nuclear could serve as a power source.

• Water can be extracted from regolith (martian rock) by baking the regolith in a furnace, the water evaporates and can the be re-condensed.

• Oxygen can be produced through the electrolysis of water. One kilogram of water produces approximately 880 g of O~2~, which is roughly enough for a day per person.

• Methane can be produced through the Sabatier process, which takes as input H~2~ and CO~2~, and can be used as a rocket fuel and to make bioplastics out of it.

• Plants are the tricky part. I will create a further post later in the future to give more detailed information about this. The basic gist is that you can create greenhouses if you have the basic ingredients (mostly water).

from left to right:

• living inside the spaceship to reduce the need for construction/habitats
• solar panels (800 m² per person gives 80 kWpeak)
• bagger + furnace (not sketched) for excavating hydrated minerals and heating them in an oven to release water
• some greenhouses (recycled water for watering is displayed)

it's my first drawing, please be kind <3
