Hi, some suggestions :
- Reinforcement from mother company
- Visiting by smugglers (trade ressources or special items) or mercenaries (corruption for dissuading to attack, giving target)
- Alone ship is lost during travel
- Discover a wreaked ship during exploration by scout (lost transporteur full of ressources, fighter prototype or powerfull alien artefact for exemple)
- Better or less ressources discovered in Asteroid colonized
- Unknown SOS detected by radar in space (bonus like wreaked ship or trap by pirates or mercenaries)
- Missions giving by mother company
- Best prices for an ressource because running out in Mars or Earth (limited time).
Very rare event : Strange aliens waking up inside colony, last survivors use self destruction protocol (initially prevent to capture by enemy company). Colony is lost but Asteroid is safe. :D
