Need some help with the spaceport

hey people. before stating the problem, i wanted to thank mr. Pancakes for making that beginner guide, because without it, i'll be a newbie forever. well, thats what i thought...

the problem is like this: i have ranked up from newbie rank, and now want to continue going to other planets for better parts and weapons. thing is:

Once you defeat him, you'll rank up, and have access to the spaceport.

now, sorry for being illiterate, but
- what is the spaceport actually? is it really the one that has a pelena in it? if it is,
- how do i unlock other selections?

please help, i love this game, its better than cosmicbreak by a mile ahead. thanks in advance.

here's a couple screenshots of what i currently think, is the spaceport::

that's not the spaceport, that's the central base.
to get to the spaceport
go to ポインドラ宇宙港

wow, i never thought it took such a short time to be replied. looks like there are still folks here playing c21jp huh? i have high hopes of meeting you guys in the game soon, especially Mr Cake and Mr Pancakes, you guys helped newbies like me so much.

Anyway thanks a ton Mr Cake for saving me from my illiteracy, cause i really thought its there with the pelena haha. now i safely arrived at gernia because of you. the space shuttle ride was something to be remembered, a feeling that cosmicbreak will never, ever give to me. its even better than getting lucky at thanks garapon and getting dieanarcams alot. thanks so much, i hope we can meet ingame and become buddies or something haha. maybe ill ask some more questions again here, since the response is really fast and clear.

here's a view of one of my best moments in the ship haha:
