The man behind Scotland's Space School has been nominated for an award in the industry equivalent of the Oscars.
Nasa run space schools from pupils around the world
Alex Blackwood is on the shortlist for a 2006 Sir Arthur Clarke Award.
He has been nominated in the category of Achievement in Education for his work with the Careers Scotland Space School programme launched in 2002.
Mr Blackwood, 53, said: "This is great news for Scotland and our young scientists." Awards will be presented at a ceremony on Saturday 8 April.
The Space School aims to increase participation of school pupils in science, engineering and technology.
Every year 3,000 students from schools across Scotland participate in the programme.
Distance learning courses supplement their studies in maths, physics, chemistry and biology.
Learning modules are developed by Careers Scotland with Nasa scientists.
About 50 young people are then selected to attend a 10-day Space School in Nasa's Space Centre in Houston, Texas.
A further 120 pupils are chosen to attend a summer school hosted by the University of Strathclyde and the University of Glasgow.
There, they meet Nasa astronauts and scientists.
Mr Blackwood, of Alexandria, West Dunbartonshire, said: "I am delighted that the programme has been recognised by the UK space community.
"The Space School initiative is frequently described as a life-changing experience.
"Early indications suggest that it is making a difference to the levels of interest in, and the uptake of, science among young people in Scotland."
