"even the researchers working inside will need to take precautions to stay healthy in the face of altitude sickness. The team plans to eventually operate the telescope remotely from a lower base facility to avoid such issues."

I assumed having the humans at lower altitude was pretty much standard for these things. I assume trying to build a structure that could be pressurized for better human comfort just to be closer to the scope would be an unnecessary expense and maintenance issue easily avoided by a lower altitude control offices.
