![]() In addition, the TRISAT-R team embarked a pair of tiny cameras, with lenses made from clear borosilicate glass to provide limited radiation resistance, mounted directly onto 320x320 pixel image sensors. This allows TRISAT-R to test a suite of radiation-detection payloads. The mission’s orbital path takes it right through the heart of the ionosphere – an electrically active layer of Earth’s atmosphere – as well as the inner Van Allen radiation belt. ![]() TRISAT-R project manager Iztok Kramberger of the University of Maribor explains: “This tiny camera measuring less than two cubic millimetres in size took a picture of an object measuring approximately one trillion cubic kilometres – our beautiful planet Earth – from thousands of kilometres away.”Ī CubeSat made from three standardised 10-cm boxes, TRISAT-R is Slovenia’s second space mission, which flew on Europe’s inaugural Vega-C launch last year to the relatively inhospitable environment of medium-Earth orbit, at 6000 km up. This unusual image was acquired using an extremely miniaturised camera about the size of the edge of a 20 cent coin – a miniscule technology experiment aboard ESA’s shoebox-sized TRISAT-R CubeSat.
