That’s just because our neighbourhood is so boring in comparison to Earth.
Imagine that by some chance Mars was another Earth with a breathable atmosphere. NASA would have been given a trillion dollar budget and we would have been there in the 80s. Instead it’s a dead red rock so NASA gets a small budget and the US spends its money on blowing people up instead.
We have the technology to be a spacefaring civilisation but we won’t care until Earth becomes a worse place to be than the rest of the solar system, which is probably never given how bad the other bodies in the solar system are. Most likely we develop Von Neumann probes before we ever get bored of Earth.
- XorNot 3y agoI do keep hoping we get lucky in my lifetime and a massive, water bearing comet with slam into Mars and jumpstart the terraforming. Watching a planet which could retain water go from "nothing to oceans" would be amazing.
- lostemptations5 3y agoEvidence suggests Mars had oceans before and they just evaporated due to the thin atmosphere and non-existant magnetic field no? I'm not sure how that would get solved without some active technological solution by humans let's say.
- XorNot 3y agoOver a timespan of hundreds of thousands of years. Which is short in geological terms, but an eternity in technological ones. We would have plenty of time to solve that problem.
- mjevans 3y agoI'm not sure which is more practical. Diverting enough material to replicate earth's natural magnetic core system on mars into the planet, or building an artificial system. The knowledge gained from attempting either is likely valuable.
- ben_w 3y agoSynthetic magnetic field is much easier than messing with the planet's core. Put a relatively small power plant in the Sun-Mars L1 point, and attach to a big conductive ring: https://phys.org/news/2017-03-nasa-magnetic-shield-mars-atmosphere.html https://phys.org/news/2017-03-nasa-magnetic-shield-mars-atmo...
- marcosdumay 3y agoFucking journalists publish an article with magnetic dipole measured in Teslas... So I go to the linked paper, and it has basically the same contents, on basically the same wording, with the magnetic dipole measured in Teslas. It appears that at some point, somebody involved with this knew what they were doing. But we are removed so many steps from that person, that anything said there could as well be Star Trek techno-jumble. Including the conclusions.
