Sam is a clever boy who loves maths. Maths is his favourite lesson. But there is something he loves more than maths - Space! He is mad about Space. He loves thinking about rockets, astronauts, satellites, Space stations, the planets, gravity, stars, red dwarfs, black holes... Anything about Space! One day, NASA organised a competition and it was to name a new shuttle. A shuttle is a type of rocket. Sam thought up a name for the new shuttle and he sent it to NASA. Sam won the competition! They chose his entry! Sam was thrilled that he named the new shuttle! The scientists at NASA invited Sam to NASA and he met some astronauts. It was a great day! They showed him a huge telescope and Sam looked right out into Space. He saw millions of stars. Then they asked Sam: 'What do you want to be when you grow up?' Sam told them that he wanted to be an astronaut, of course! And what name did he choose for the new shuttle? Serafina. It was the name of Sam's cat. The astronauts loved the name. Now, Serafina the Shuttle is orbiting Mars and Serafina the Cat is orbiting the fireplace.
