A persistent browser MMO set in a 1:1 scale solar system built on real NASA MOLA/LOLA altimetry data, with real orbital physics. Explore the planets, mine asteroids in real-time skill-based instances, refine and craft using a periodic-table economy, trade in a player-driven market, and fight aliens in a fully cooperative universe where nothing ever resets. Free to play, no download — runs in any browser, including mobile.
