I suggest you go on YouTube and find a walkthough or go on a FAQ.
Go to Space Center and......you will see Team Magma.
This is not the team magma cave that is team aqua cave. Team magma cave opens when you have the magma symbol.
You must beat the gym leaders,then go.They will be there.Good luck fighting!
When u get your badge there and go to the space shuttle.Then you talk to Team Magma's boss and Steven will pop out of no where and ask if he can fight with u.

They will come and try to steal the fuel from the space station. This takes place after you have beaten the Mossdeep gym leader
