AstroMC is a survival server that feels like space and tech but it is still vanilla Minecraft with no mods.

You start on Earth and the goal is to progress through a full tech style system and eventually go into space. There is a small galaxy with different planets. Each planet has its own ores and resources and there are new mobs being worked on.

The server has a lot of tech type features. There are things like logistic style pipes energy systems quarries and automation so it feels like a modpack but you do not need any mods.

The world is not calm either. There are disasters like tornadoes and earthquakes plus seasons and a thirst system. All of this makes survival harder and makes progression feel more serious.

If you like grinding progression tech and space themes this server is built for that style of play.
