Satellite is a very good way to get the information of a planet before you get there. you can get information of planet like: Heat,Day/Night time,Air ingredient(Some planet may have toxic gas) or any kind of inormation...you may send it to the planet you want by special tire rocket,from earth to space station. Space debris is the worst thing you can ever meet in space. Some time you may lost some stuff in space,they will become Space debris,they may stay at where they are, or become a bullet and destory your space station. anti-satellite multistage missile is a good way to destory people's space station or satellite! Idea From ICBM,you may launch a kind of anti-satellite missile to space,they will target player's space station or their satellite and destory it. Radio town,Track your satellite or space station,or even find else player's space station. Like the one in the ICBM,but more powerful,it don't track the mob,only tracking the thing flying on sky. Also...The defferent Day time at defferent planet There is 24 hours on earth of a day,but not for every planet in solar. add 10/13: Information block I guess most of you used the IC2's addon Nuclear control,if NO,then there is how it work This block will get the information inside the room,if you are in a full cover place,it will show the text of information on the screen(as a side of block texture),if you got 30% oxygen in this room then it show 30% O,and it will also show heat,time,anything useful. Other solar system??? Get better engine first! Well,it take very long to get other solar system for now,so in minecraft,we need a very special tech named Warp core from Star Trak,you will only able to launch it in space, this idea is about we need some other way to get power,easy to say... STOP BURN STUFFS,Now the newest rocket will be tire 3,Not sure what will it be but, I wish we can stop brun stuff to get speed power at least tire 5 rocket,no need to be Warp core,just something else. My ideas will not only for Galacticraft it self,sometime it will up to mods API,by the way add a Idea Buildcraft engine can get more engery on space. Why? Because on earth,the BC engine work as a piston,the gravity will make it push harder to gen power, But if we are in a zero or lower Gravity place,we may need less power to push piston to gen MJ,that mean a Buildcraft engine may be able to gen more power in one minute than on earth. but if we are in heavyer gravity place,then...you know!
