Mars probably won’t be terraformed all at once.
It’ll be terraformed in pieces.
Paraterraforming sealed biodomes, aerogel-covered habitats, and closed-loop ecosystems sidesteps several of the hardest problems with trying to remake the entire planet.
Open liquid water on Mars is not automatically your friend.
Expose it to fresh basalt and you restart a geochemical carbon sink: water + basalt + CO₂ → carbonate minerals such as siderite.
On Earth, plate tectonics eventually recycles carbonates.
Mars has a stagnant lid.
Once that carbon is locked into rock, there is no planetary-scale recycling engine bringing it back.
So instead of fighting an entire planet:
> Contain the atmosphere.
> Contain the water.
> Isolate it from reactive regolith.
> Build the climate locally.
Silica aerogel is especially interesting because a thin layer can transmit visible sunlight while trapping heat beneath it a solid-state greenhouse capable of creating localized warm zones without thickening Mars’s entire atmosphere.
Inside those protected environments, cyanobacteria, algae and other photosynthetic organisms could begin producing oxygen and biomass from Martian CO₂ and water.
Then comes the harder engineering problem:
Dust storms.
During severe planet-encircling storms, surface sunlight can collapse by well over 90%, shutting down photosynthesis and crippling solar power simultaneously.
That means a serious Martian biosphere cannot be solar-only.
It needs dispatchable baseload power.
For a ~100 m² experimental biodome, maintaining lighting, circulation and thermal control during extreme opacity could require roughly 10–20 kW of continuous electrical power.
Nuclear becomes extremely attractive because the reactor does two jobs:
⚛️ electricity for LEDs, pumps and ISRU
🔥 waste heat for the habitat
Add aerogel insulation, optimized red/blue LED lighting, controlled photoperiods and metabolic dormancy modes, and the system becomes dramatically more resilient.
The path to a living Mars may not begin with changing the planet.
It may begin by building thousands of small artificial climates that Mars cannot chemically destroy.
Not terraforming.
Paraterraforming.
@ResisttheMS EMP could fix every problem. The problem is AI making an invasion in every computer on earth and it’s a global shutdown after this. Every digital money who is on trades, crypto etc would be gone. Every bank is working digital. In a financial case the world would stop
Bill Gates wants an international body to regulate AI.
“It's not the role of the industry to self-regulate or understand the whole-of-society impact that comes out of AI … The depth of understanding of AI … is too low in every entity, including the government.”
In his view, no single entity understands it well enough yet.
