Welcome back to our series on Martian colonization! In Part I, we looked at the challenges and benefits of colonization. In Part II, we looked at what it would take to transport people to and from Mars. In Part III, we looked at how people could live there. Today, we will address the question of how people could establish an industrial base there.
If we intend to “go interplanetary” and establish a colony on Mars, we need to know how to address the long-term needs of the colonists. In addition to shelter, air, water, food security, and radiation shielding, the people will need to create an economy of sorts. The question is, what kind of industry would Mars support?
There’s Gold in Them Thar’ Hills!
One of the main reasons why Mars is considered an attractive location for a colony is the similarities it has to Earth. Like Earth, it’s a terrestrial (aka. rocky) planet that’s composed primarily of metals and silicate minerals, which are differentiated between a metallic core and a silicate mantle and crust.
From a pile of seaweed to a packet of soy sauce.
The London startup Notpla has created a plastic alternative from seaweed that’s biodegradable — and even edible. And it’s hoping it could put a dent in the 300 million tons of plastic waste humans generate each year.
Notpla’s natural plastic-like casing is biodegradable within four to six weeks, the company says, compared to the several hundred years it takes synthetic plastics to biodegrade.
The technology doesn’t seem to be here yet; obviously, the ice on Mars will be harvested to provide drinking and irrigation water.
If we ever intend to send crewed missions to deep-space locations, then we need to come up with solutions for keeping the crews supplied. For astronauts aboard the International Space Station (ISS), who regularly receive resupply missions from Earth, this is not an issue. But for missions traveling to destinations like Mars and beyond, self-sufficiency is the name of the game.
This is the idea behind projects like BIOWYSE and TIME SCALE, which are being developed by the Centre for Interdisciplinary Research in Space (CIRiS) in Norway. These two systems are all about providing astronauts with a sustainable and renewable supply of drinking water and plant food. In so doing, they address two of the most important needs of humans performing long-duration missions that will take them far from home.

With fall and winter holidays coming up, many will be pondering the relationship between food and sleep. Researchers led by Professor Masashi Yanagisawa at the University of Tsukuba in Japan hope they can focus people on the important middlemen in the equation: bacterial microbes in the gut. Their detailed study in mice revealed the extent to which bacteria can change the environment and contents of the intestines, which ultimately impacts behaviors like sleep.
The experiment itself was fairly simple. The researchers gave a group of mice a powerful cocktail of antibiotics for four weeks, which depleted them of intestinal microorganisms. Then, they compared intestinal contents between these mice and control mice who had the same diet. Digestion breaks food down into bits and pieces called metabolites. The research team found significant differences between metabolites in the microbiota-depleted mice and the control mice. As Professor Yanagisawa explains, “we found more than 200 metabolite differences between mouse groups. About 60 normal metabolites were missing in the microbiota-depleted mice, and the others differed in the amount, some more and some less than in the control mice.”
The team next set out to determine what these metabolites normally do. Using metabolome set enrichment analysis, they found that the biological pathways most affected by the antibiotic treatment were those involved in making neurotransmitters, the molecules that cells in the brain use to communicate with each other. For example, the tryptophan–serotonin pathway was almost totally shut down; the microbiota-depleted mice had more tryptophan than controls, but almost zero serotonin. This shows that without important gut microbes, the mice could not make any serotonin from the tryptophan they were eating. The team also found that the mice were deficient in vitamin B6 metabolites, which accelerate production of the neurotransmitters serotonin and dopamine.
Artificial intelligence is being applied to virtually every aspect of our work and recreational lives. From determining calculations for the construction of towering skyscrapers to designing and building cruise ships the size of football fields, AI is increasingly playing a key role in the most massive projects.
But sometimes, all we want to do is move a can of beans.
According to a recently published abstract by researchers at the University of California, Berkeley, they have developed a mechanism that “couples a perception pipeline predicting a target object occupancy support distribution with a mechanical search policy that sequentially selects occluding objects to push to the side to reveal the target as efficiently as possible.”
Sales for the category have exploded as the pandemic disrupts business as usual. Is this because people are turning away from animal-based eating, or is it keeping with the segment’s trends?
