Astronauts need brains AND brawn! Using your coordination, endurance and quick thinking, perform five jumping jacks, with a star-jump finish, while calling out the liftoff sequence: "5,4,3,2, 1, liftoff!". Repeat it again with one catch – call out the liftoff countdown in another language!

Film it, or snap a picture, and tag it on social media with #trainlikeanastronaut.
