The astronaut Tim Peake will be guest speaker at a major space conference for young people in York today.
It's being hosted by the University of York and will involve hundreds of youngsters showcasing their projects linked to Tim Peake's Principia mission.
Mr Peake had previously said he hoped to attend the conference .... 'subject to operational requirements'. But a tweet he posted yesterday afteroon saying he was on a train bound for York has delighted delegates.
Mr Peake made history earlier this year when he became the first astronaut representing the UK to complete a spacewalk.
The Department of Physics does a tremendous job at delivering outreach activities to schools and the public, reaching many thousands every year. The Department's observatory, Astrocampus, is the hub for astronomy and astrophysics, both at the University of York and for the local area.
