# Expansion Missions

Expansion Missions are ongoing projects that introduce new inventory into the Mars economy. They come in four types: Construction Missions for buildings, Convoys for astronauts and equipment, Innovation Missions for discoveries, and Surplus Missions for highly sought-after items. Here’s how to get involved:
