Tim Peake's message for Limavady boy with autism

It's not everyday you get a message from a real live astronaut, but that's what happened to seven-year-old Hayden Geraghty.

Hayden, from Limavady, has autism and had limited speech until a momentous day in his life and the life of the astronaut Tim Peake.

As the astronaut was being launched into space in December 2015, Hayden began to say the count down to the rocket's take-off.

Since then, his speech has improved dramatically.

On Wednesday, Major Tim, who became the first British astronaut to blast off to the international space station, tweeted to say he was "delighted" that Hayden was making such great progress.
