Super metroid- after the end?

Hey, I've been stuck on this lately.

I beat mother brain and got sent back to the save station in Tourian, the one that I saved in right before beating mother brain. I reloaded my game from there, but the door that leads out of Tourian is grey (metal).

Is there any way to get out of tourian after having beat mother brain?

As said before, we've all been there. The good part about this is, well, nothing, but you now know. You can however beat the entire game in about 2 hours now that you know you're way through. I suggest trying to do a speed run and this time save outside. Go for 100% item completion this time, that makes the game good fun.

Ah yes, the infamous point of no return. You just have to have a save before that point with the giant hatchling, unfortunately.MAILER_DAEMON
