Editing Clarke Orbital Assembly Ladder (section)

=== Conceptual Origins and Early Proposals ===
Theoretical groundwork for a partial orbital tether had circulated within engineering circles since the mid-twenty-first century, but practical proposals awaited both the material science advances of the 2060s and the institutional momentum generated by the [[First Sustained Mars Surface Missions]] of 2031 CE. As interplanetary ambition outgrew chemical-launch budgets, pressure mounted to find a structural solution to Earth's gravity well.

[[Engineer Yuki Tanaka]], then a senior structural analyst within the Commission's orbital logistics division, published a detailed feasibility report in 2081 CE that became the definitive technical argument for proceeding. Tanaka's report identified the Columbia Basin as the preferred anchor region on the basis of seismic stability, proximity to existing rectenna infrastructure, and political accessibility. [[Director Amara Sousa-Nkemdirim]], chairing the Commission subcommittee responsible for orbital infrastructure, used Tanaka's report to secure treaty approval and multi-body funding in 2083 CE, citing the Ladder as indispensable to meeting projected habitat tonnage targets through 2110 CE.
