X-Rays from Space

On 2 June the new all-British satellite, Ariel 6, was put into orbit more than 600 km above the earth's surface. Like its highly successful predecessor, Ariel 5, one of its main tasks will be to study x-rays and cosmic rays from deep space, and it is carrying experiments from four British universities. Patrick Moore talks about this new astronomical satellite with Dr Leonard Culhane, the project scientist for the mission.
