Before we build a Mars colony, why don't we build a 100% self-sustainable test colony in the Antarctic?

The colonization sites under consideration would be in the mid latitudes or equatorial, and would be more like Arizona than Antarctica in terms of sunlight, with a near 24 hour day/night period and ...

Before we build a Mars colony, why don't we build a 100% self-sustainable test colony in the Antarctic?

One reason for not starting a new one is that we have already built several: Flashline Arctic Devon Island Utah Dessert Sealed 500 day missions Hawaii Underwater And the actual antarctic stations, one ...

Is a dome really the most efficient way to contain gas in a vacuum?

It all depends on the material. A dome/balloon is mechanically same thing as an arch, just loaded in the opposite way. The material of a balloon is all under tension, the material of a masonry arch is ...

Before we build a Mars colony, why don't we build a 100% self-sustainable test colony in the Antarctic?

The conditions in Antarctica are very different from Mars so building a base there is not a good analogue. There is a near a vacuum on Mars and the amount of sun light received on Mars would be much ...

Nuking mars for colonization

Fusion bombs have existed for decades, they are called thermonuclear weapons, and are many thousands have been produced. A thermonuclear bomb uses a small fission bomb primary to cause the extreme ...

Is a dome really the most efficient way to contain gas in a vacuum?

Engineering Trade Offs Everything in Engineering is about trading something for something else (cost for time, strength for weight, etc.) In the 1960s, solar panels and grow lights were both immature ...

Is a dome really the most efficient way to contain gas in a vacuum?

Technically, assuming the dome was made of a material strong enough to hold in the air, and the internal atmospheric pressure doesn't get too high, the dome should keep from exploding. The main ...

Is a dome really the most efficient way to contain gas in a vacuum?

Structures under internal vacuum or compressive loads can be fairly complex to analyse, as they can buckle. Structures under tension or internal pressure are much simpler. These structures use ...

Before we build a Mars colony, why don't we build a 100% self-sustainable test colony in the Antarctic?

There are three main location categories for analog tests for Mars colonization: Lunar base Space station Biosphere on Earth A lunar base will have the highest fidelity, providing an environment ...

Nuking mars for colonization

when fusion bomb technology is proven, couldn’t we just use that to colonize mars instead No. Fusion bomb technology is already proven, but it is entirely inadequate for terraforming. or do we just ...

Could a framework of mirrors static in space above the Lunar south pole illuminate a moonbase there continuously?

Answer: No, it ain’t gonna work. Pole-sitter orbits for the inner planets (using a combination of light sail pressure and low-thrust propulsion) have been modeled. https://www.researchgate.net/...

Asteroid orbiting between Earth and Mars as ferry?

One would most likely want to lasso a water-ice comet like 238P. The H2-O2 fueled rockets would carry nuclear reactors, water mining equipment, and H2O splitter. They would plug into the "gas ...
