Welcome to Aperture Space Exploration. I am Cave Johnson, basically the found er of Aperture Science and its other sectors. If you are a test subject in the original Aperture Science, file out a form to be transfered from there to here. As of today, we are using the handheld portal device for space travel to make better airlocks. (loudly) And a certain someone needs to make better rockets! Greg's the rocket designer and whenever someone touches the rocket, it falls apart.
