So today I would like to bring in another gameplay mechanic - Exploration.
Feeling adventrous? Here it goes!
Basically exploration will help colonists understand the planets (i.e, research) as well obtain some surplus resources from somewhere. A exploration will always award you some resources, based on the grid explored, exploration scale and your fleet scale. Some grids can even establish outposts to get surplus resources periodically, but has to be manually collected, and requires some population, food and water to begin production.
Exploration is classified into Surface Exploration and Stellar Exploration. The previous one has lower cost and risk however with less yield and booty; the later one has more unpredictability and costs starships but has lot more yield.
