2026-10-24 In the Solar System view you can now list and fly to every spacecraft, and time can run at 1 hour, 1 day or 30 days per second to watch planets move.
2026-10-24 Choosing a moon, planet or spacecraft in the side panel opens its card, and on phones the panel folds away so the map stays visible.
