FULL SYSTEM OVERVIEW

The entire plan was analyzed against the **NASA Technology Readiness Level (TRL) scale**—the global standard for measuring a technology's maturity.


The analysis, which is available in the full report, concluded the following:

* **The EGS Furnace (Pillar 1)** has a high TRL, validated by the real-world success of the Utah FORGE project.

* **The HAPS Ladder (Pillar 2)** has a high TRL, de-risked by the multi-billion-dollar commercial HAPS industry.

* **The Orbital Hub (Pillar 3)** has a very high TRL, based on an evolution of flight-proven hardware (like the ISS radiators).


**The Conclusion:** The "Direct Path" has an overall feasibility rating of **65-80%**. The remaining challenges are not in new science, but in **engineering, manufacturing, and integration**. It is a tangible, achievable project for this generation.
