CU Science Discovery and Fiske Planetarium are teaming up to offer regular in-person WHIMC workshops and summer camps for kids who would like to visit our crazy-cool “What-if” worlds and exoplanets and also work in teams to build mars habitats to later share. This is the best way to explore the server, especially for kids without their own Minecraft Java Edition accounts.

Alternatively you can explore the International Space Station subject kit or Artemis Missions with Minecraft Education Edition. If you can’t connect to our server for whatever reason you can download individual worlds and resource packs at Planet Minecraft or as a bundle from us.

Otherwise you should be all set to join us at
