Three sixth-form students are back home after attending this year’s United Space School in Houston, Texas.

All pupils at Ballakermeen High School, they were selected to attend the school on a River Advisers scholarship, which this year celebrated its 25th anniversary.

Siobhán Fletcher went to meet this year's cohort - Hollie Patterson-Hannay, Patrick Williams and Guy McGuinness, as well as Chris Stott and Dr Jennifer Stone from the company, to find out more.
