🚀 Top Astronomer Warns That Elon Musk's Mars Plans Are a Dangerous Delusion | Futurism
「 "I don’t think it’s realistic and we’ve got to solve those problems here on Earth," he said. "Dealing with climate change on Earth is a doddle compared to making Mars habitable. So I don’t think we should hold that out as a long-term aim at all." 」
#SciFi#ScienceFiction#SpaceExploration#Mars#Capitalism#SiliconValley: "If you listen to the libertarians pushing the notion of space settlement, you could be tricked into believing that Mars is some kind of distant paradise-in-the-making that we need only seize and remake for our species. As the crises escalate here on planet Earth, the solution isn’t to do all we can to make a world that works for all, but to find a new frontier that will magically cure all of our ills. Except there isn’t an ounce of truth in those stories.
Mars is no backup planet. It’s a hostile world where humans can’t breathe without technological assistance, can’t walk freely on the surface without a space suit, and would have to live far underground to avoid developing cancer from the radiation on the surface since the world has no magnetosphere. As Zach and Kelly Weinersmith explain in A City on Mars, the soil on Mars is toxic and not as easy to clean as boosters of space settlement like to suggest. There’s also very little research on the social and biological considerations of long-term habitation in space, particularly reproduction and child rearing in a hostile environment that lacks the gravity we’ve evolved to live with. And that’s before considering the legal questions that people like Musk pretend don’t exist.
There’s no future for humanity in space — or at least not for such a long time that it’s pointless to make sacrifices to try to realize it in the present. Intergalactic travel and adaptation to different planets seems easy in science fiction because the challenges can be ignored or explained away so as not to get in the way of the story — and there’s nothing wrong with that. Science fiction’s job isn’t to predict the future, but to use an imagined universe as a setting to probe the problems of the present." https://disconnect.blog/what-if-we-never-live-on-mars/
The possible identification of a previously unknown Martian volcano has made waves across the planetary sciences community since Mars Institute Chairman Dr. Pascal Lee, lead author of an abstract about the formation, presented the findings on March 13 at the 55th Lunar and Planetary Science Conference in The Woodlands, Texas.
The research has drummed up excitement — and attracted some skeptics.
Elon Musk uses sci-fi dreams like colonizing Mars to distract us his real business goals and how SpaceX has trampled workers’ rights and the environment to achieve them.
If we ever hope to build a better future, we need to stop falling for false futures.

Le rover se dirige vers une zone riche en carbonates en longeant le lit asséché de la rivière Neretva.
L'horizon diffus témoigne que l'atmosphère est très poussiéreuse. Une tempête de poussière est en effet passé sur le cratère Jezero il y a quelques semaines. https://www.flickr.com/photos/thomasappere/53617450798/in/dateposted-public/

Note: Full high-resolution frames are usually about 1 km across; however, this image was cropped. This skylight is still probably several hundred meters across.
#ElonMusk just proved how absurd, and detached from reality he is. In the mind of this ultra-wealthy apartheid supporter, pretty much everybody can afford a $100,000 ticket to #Mars by simply working hard, and saving their money! Meanwhile, back on Earth, more than half the country can't afford an unexpected $1000 emergency. Fuck you, Elon.
A team of European scientists have published the most detailed geologic map of Oxia Planum – the landing site for ESA’s Rosalind Franklin rover on Mars. This thorough look at the #geography and geological history of the area will help the rover scout the once water-rich terrain, in the search for signs of past and present life.
A 280-mile-long volcano may have been discovered on Mars—hiding in plain sight
The colossal volcano is taller than Mount Everest, would reach from New York City to Washington, D.C., and may be a promising site to look for ancient remnants of microbial life.
Le rover Perseverance roule actuellement le long des rives de l'ancien fleuve Neretva Vallis, depuis bien longtemps asséché. On le voit qui serpente ici vers l'est. Au loin, le rempart du cratère Jezero se perd dans l'atmosphère poussiéreuse. https://www.flickr.com/photos/thomasappere/

It's not every day that a giant volcano is discovered hiding in plain sight. By reviewing satellite imagery from many missions, scientists have spotted the remains of a colossal volcano on Mars. The volcano, provisionally named “Noctis Mons,” had been imaged repeatedly since the early 1970s, but extensive erosion had concealed it from view. Researchers have also spotted hints at an adjacent glacier buried underneath the volcanic slopes.
