This week the clubhouse reaches for the stars with a space special! Let's Goers Mason and Matthew explore a new world underwater when they try out scuba diving. CBeebies stargazing scientist Maggie Aderin-Pocock joins us for some rocket-fuelled fun, helping Joanna make and launch paper-cup rockets, and Craig spots some shooting stars with a bit of a difference! Abe has a new, anti-gravity Cool Move - The Astronaut - to watch and learn. There are out-of-this-world animated facts all about space, and more super Send-Ins from CBeebies viewers. Plus everyone is singing and dancing with the Get Set, Let's Go! song, and a boogie-brilliant Club Dance.
