The series was a hoax at the expense of its contestants, who were told they were being trained as cosmonauts at a Russian military base before undergoing a five-day trip into low Earth orbit. In reality, the entire series was filmed in Dore, and the contestants did not leave Earth.
It was a great setup, but ran out of steam in the last episode, I think.
Also one of Michelle Mylett’s first roles before she went on to star in Letterkenny.
