Pupils at Sandringham School in St Albans are getting the chance to speak to astronaut Tim Peake live from the International Space Station.
To celebrate the occasion, they've been throwing a Space Festival at school - making models and even cooking space-friendly food!
School Reporters Kallum and Sebastian have been finding out more.
