After 5 ingame years, the 'tribe' feels ready to start work towards a gravship. After looking at the recipes, it seems clear we don't have nearly enough steel or plasteel to get thing really ready, so the core will be sitting on our stockpile for a while still, but I hope to have something airborne within maybe 2 years. At least we already have 3 colonists with recon armor+cataphract helmets that can be sent into orbit to maybe mine some asteroids or something, but our greatest priority currently is still getting the necessary plasteel and steel, and the deep mining scanner really isn't cooperating much on this front.
