Space Cadets was a British television programme made by Zeppotron for Channel 4. Presented by Johnny Vaughan, it was aired across ten consecutive nights beginning on 7 December 2005
The concept of the show was that a group of twelve contestants - who answered an advert looking for "thrill seekers" - were selected to become the first British televised space tourists, including going to Russia to train as cosmonauts at the "Space Tourist Agency of Russia" (STAR) military base, with the series culminating in a group of four embarking on a five-day space mission in low Earth orbit.
The show and space mission contained aspects of Reality TV, including hidden cameras, soundproofed 'video diary' rooms and group dormitories. However, the show was in fact an elaborate practical joke, described by Commissioning Editor Angela Jain as Candid Camera live in space.
I had forgotten all about this on account of only watching 1 episode and then deciding it was utter shite. (IMO, as the kids say!)
