Cosmos mission
Moons, probes and nameless stars. Cosmos is one of the themed missions in OnlyClick: 50 stages and 250 questions, with 12,921 accepted answers. It begins with the planets and works outwards, past famous telescopes and probes, to the moons, craters and call signs that only real space fans remember.
The route runs from “Say Hi to the Sky” to “Starry Finale”. The first stages are free to fly, and later stages come with the full mission. Rarer answers fly you farther, and it takes enough thrust to clear each stage.
