The Man With the Yellow Hat's about to get a big job! He's going to go up into space to fix the Einstein-Pizza Space Telescope, which is broken & pointed right at Pizza's kitchen window. Dr. Einstein & Professor Pizza explain that the spaceship has a self-locking air lock but they accidentally forgot to make a way to open it from outside. George has to tag along to push the button that'd let him in but is forced to go outside & do the job when the Man's tether breaks. Worse off, George's told he has only 2 minutes of air to complete the job.
