The Wheel That Wasn’t: A Century of Rotating Space Station Concepts

The article surveys the long-running fascination with rotating, gravity-generating space stations—from early ideas by Oberth and Noordung to mid‑century experiments (Convair’s MARS, TASSEL/MTSS, Olympus, MOL) and the Soviet‑era Salyut/Almaz programs—progressing through docking milestones and into the modular, non‑rotating habitats of Skylab and Mir. Despite serious engineering interest in artificial gravity, the cost and practicality kept wheels from becoming reality, so rotating stations remained theoretical while non‑rotating, modular stations became the practical path forward. The piece closes by echoing the irony that the “wheel” concept has persisted as history’s curiosity rather than a future reality.
