Next month Tim Peake will be the first British astronaut to go on an official mission to space.
But back in 1991 a British woman Helen Sharman also went to the international space station.
It was after answering a radio advert and beating 13,000 applicants to take part in Project Juno, which was a Russian funded space mission. She spent 18 months training in Star City, 30km north-east of Moscow.
During her eight days in space, she carried out medical and agricultural experiments.
Helen spoke to Dick and Dom about her space adventures.
