Vulture's Statue

S1, E16: When Vulture demands that a larger statue of his glorious image be erected on the school campus, the funds must come from somewhere – and the first casualty is the school’s large telescope. After all, who needs a “stupid old telescope”? The Space Racers are soaring through space all the time, he reasons; they can see whatever they need to see with their own eyes. Problem is, once the telescope is gone, no one notices a massive comet on a dangerous trajectory for their space station on the moon! Now the cadets need to race against the clock to somehow avert the impending disaster, when some simple observation in advance would have made their job a lot easier.
