Theoretical Physicist: Colonizing Mars Is a Ridiculous Idea

Making Mars habitable (terraforming) has been kicking around engineering circles for decades. What are the chances, given Moore’s Law-level increases in technology?

And so what does a theoretical physicist know about it, you ask? Well, when it’s Sabine Hossenfelder, she is alwaysworth listening to: The biggest problem is not that Mars is “minus 60 degrees Celsius or minus 80 Fahrenheit,” she explains, but that it has no magnetic field so the atmosphere was blown away by the solar winds. So to form Mars into a second Earth, we would first need to give it a magnetic field. How easy is that?: In a paper that was just published in April in the International Journal of Astrobiology, two physicists explain that all you have to do put a superconducting wire around Mars, simple enough, isn’t it? The circle would have to have a…

Sci-fi Saturday: When Terraforming Mars Means Mars-forming People

In this award-winner, the underground humans must, according to the terraforming colony's rules, deny emotion, which pretty much guarantees a story

“New Mars” at DUST by Susie Jones (March 30, 2021, 19:14 min) Earth is no more. A new generation lives underground on Mars preparing to begin a new life as the colonists of a planet which is being terraformed into a new habitable world. ‘New Mars’ is a society driven by science and logic to ensure humans will not make the same destructive decisions this time round. But two young hopefuls struggle with the intensity of their feelings – which inadvertently propels them towards an unexpected truth about their existence. (IMDB) “New Mars” premiered in 2019 and has won a number of awards. It conveys the claustrophobia of an underground world where death rules the planet’s surface. Life on a…

Why Search for Extraterrestrial Life? Why Not Make It Ourselves?

A NASA astrobiologist’s bold suggestion is likely to spark debate

Recently, we have been looking at the question of why we don’t see aliens, with as many as 75 hypotheses offered. But one astrobiologist has a bold suggestion: Why not just seed life on various suitable exoplanets, once we have the means to do it? We need not search for extraterrestrial life if we can learn how to create it ourselves. There are a lot of reasons to think very carefully about doing something like that, as Betül Kaçar (pictured), director of the NASA Astrobiology Consortium MUSE, acknowledges: Rather than regarding the overwhelming majority of planets and moons as failures unworthy of further study, we should instead recognise them for what they are: they’re not empty. In fact, a very…
