Two teams touch down at the STARS space station to take on three scientific challenges to win out-of-this world prizes. First, the teams must identify objects using just one of five senses. Then, in a game based on energy, they have to pedal bikes to power up lights and launch a rocket. Finally, a player from each team must memorise a pattern of animals on the Memory Path, before guiding their partner across it.
