If you wanted to make a Space Station in Waste Of Space and still don't know how to go to space i recomend taking a look at Building A Ship and then coming back here.
First, inside a planet you make a pole, then you add a floor and a anchor, activate the anchor and remove the pole, now you just need to make the body of your station.
The components for your station:
Spawn point - Used for respawning on where it is, add at least 3 to make sure it's safe for you and lock them.
Power Cell - Use at least 2 power cells to mantain your power up to 100k energy, you will need to make them 10x10x10 soo that both have 50k energy.
Solar Panels - They will generate energy every second on space, since there isn't night or day in space and the sun is always visible, it's important that you have at least 4 solar panels for lights and air supplyers.
Lights - Space is kinda bright but probabbly dark inside your station, add lights on the ceeling to light the place soo that you can see what you are doing.
Air Supply - There's no air in space, there's only vaccum, soo, you will need only 1 powered air supply soo that you can breathe. But, depending on the size of the station you will need more air supplyers. OBS: One air supply has a range of 300 studs of where you can breathe.
Hyper Drive - You will need one to travel between regions(Planets or Solar Systems)
Star Map - This goes along with the hyper drive soo that you can search for planets, then you can click on the planet you want to go and it will seet the cords on the hyper drive.
Telescope - Another part that goes along with the hyper drive, same thing as the star map but it will set the cords on the telescope soo you can click on the planet and then on the telescope to take a look on how the planet is.
Radar(Optional) - Using a radar can be usefull sometimes, for example, it can locate aliens or ships, when you see a yellow arrow far from the green arrow and mooving towards your location or another, it's probabbly an alien or another ship. Also the radar can be a little decoration.
Teleporter(Optional) - You can use teleporters in case you need to travel to somewhere else but faster, it will use 1k energy when triggered and you must stay on top of it to work, it will also need the cords and a ID.
Turrets - To keep away enemies like aliens, make four platforms around the station and mount turrets on them, search for turret tutorials and customise them the way you want.
Energy Shield - This will create a bubble around it when powered, use it to defend the station from anything. Depending on the size of the station, change the shield size (it will use more or less energy depending on the value)
This is it for now, i will think of other stuff later, have fun!
