Students have captured images of Earth after launching their own mission.
The pupils, from Giles Academy in Boston, Lincolnshire, used a balloon fitted with an iPhone and camera to take pictures from 18 miles above the planet.
A parachute system was then used to return the equipment - which was tracked using satellite technology - to Downham Market, Norfolk.
The flight captured more than two-and-a-half hours of footage.
