Rush to space

Space Age challenge. Research any tech using another planet's science pack (Metallurgic, Electromagnetic or Agricultural) before you've unlocked Production or Utility science. In other words, skip the back half of the Nauvis tech tree and rush off-world early: get to Vulcanus, Fulgora or Gleba, stand up its science and research with it before you touch purple or yellow. A deliberate detour best done on a focused run - Vulcanus is the usual pick as the friendliest first planet.
