Study Says Mars Terraforming Needs 380 Terawatts for 1,000 Years, Pushing Habitability Centuries Away

Summary
A new APS Open Science study by NASA JPL's Slava Turyshev finds Mars terraforming is theoretically possible but effectively out of reach for centuries with current technology.
380 terawatts of continuous power for 1,000 years would be needed just to generate enough oxygen for a breathable atmosphere—about 20 times current annual global energy consumption on Earth.
10^18 kilograms of atmospheric gas, a 60 C average warming, and 8.2 x 10^17 kilograms of oxygen would be required; proposed heating options include nanoparticles, CO2 release, or vast orbital mirrors.
70 million square kilometers of mirrors would be needed under one sunlight-concentration approach, while the oxygen target would require splitting water equal to about six cubic meters per square meter of Martian surface.
The study says Mars does appear to hold enough accessible ice—roughly five times the water needed for the atmosphere—making smaller-scale paraterraforming greenhouses a more plausible near-term path than full planetary transformation.
With terraforming deemed nearly impossible, how does SpaceX's plan for a million-person Mars colony still hold up?
If its weak magnetic field isn't the dealbreaker, what overlooked challenge could actually stop us from colonizing Mars?
Mars Terraforming by the Numbers: Why Full Planetary Habitability Remains Centuries Away
Overview
A major 2025 study led by Dr. Slava Turyshev at NASA’s Jet Propulsion Laboratory provides a clear engineering analysis of Mars terraforming. The research shows that, while the basic physics and raw materials for making Mars habitable are understood, the real barrier is humanity’s current lack of industrial and energy capacity. Transforming Mars into a world suitable for life would require technology and resources far beyond what we have today, making full planetary habitability a challenge that will take centuries to achieve. For now, Mars remains a destination for exploration, not a second home.
