What '90s Nickelodeon show am I thinking of?

I’m a child of the ‘90s, and as such, I had extensive exposure to the Golden Age of Nickelodeon television programming, particularly their action and physical challenge-oriented gameshows. I remember the names of most of these shows pretty accurately, but there is one in particular that, despite my research and excellent google-fu, I am unable to find the name of. Perhaps you can help me, Fluther? I recall the kid contestants on the show having to don very futuristic looking, sci-fi style gear, including a unique helmet and answering questions before running through a maze and being interrogated by a giant floating head on a screen. At the end of the show, the winner would cross their arms over their chest and a cheesy, 1995tastic animation of them rocketing into the cosmos would play.

So am I being a good little Freudian and fabricating these memories, or was this an actual show? If so, what was it called? Was it even aired on Nickelodeon, or was it *gasp, Cartoon Network? Thanks in advance, my Fluther lovelies.
