TL;DR
Building differents payload to launch with silo to get differents resultsWhat ?
Add researches and receipes for differents kinds of satellites. right now the satellites are made with radars. Replace those radars with another component for :- a scientific/high tech payload : build a sat. with science labs
=> get the space science packs ( as it is currently) - a scanning payload : build a sat. with radars (like the one we have currently)
=> reveal a large (maybe random) portion of unexplored map. Or a fixed amount in every direction. - a military payload : build a sat. with artillery shell/nuke/explosives/etc
=> get the option to make an orbital strike at any point on the map, clearing bitters, forest, cliffs... [not in multiplayer mode] - a manufacturing payload : build a sat. with assembly machines
=> get...hmmm... rock ? debris from previous launches ? a thank you note from the dev ?
Why ?
To add some option in the endgame, based on the path you want to choose.Plus we lack some long range scanning without military researches (or i missed it ? ). Trainworld require large exploration and oceans are hard to cross
