GPT-6.1 Sol plots a 3-day Earth-Mars transfer orbit, but a Codex app update locked the session

The author's first experiment with the new GPT-6.1 Sol (High) model: inspired by The Expanse, they asked it to plot a fast Earth-Mars transfer orbit assuming a constant 1/3 g acceleration so Belters could walk comfortably on the ship. With optimal planetary alignment, the trip takes only about 3 days — an impressive result.
The catch: the session was run from a phone on the legacy Codex cloud, and after updating the app the author could no longer access it. A friendly assistant dot named "Loop" helped recover the animation from the inaccessible session.
