A new hyperspectral camera able to fit in the palm of a hand, compact enough to fly on CubeSat-sized missions, is being developed by ESA.
Hyperspectral instruments divide up the light they receive into hundreds of very narrow, adjacent wavelengths to reveal 'spectral signatures' of particular features, crops or materials, providing valuable data for fields such as mineralogy, agricultural forecasting and environmental monitoring.
These cameras are typically bulky items of 100 kg or more, requiring costly full-sized satellites. But advanced electronics and new materials and methods are opening up new possibilities for miniaturising payloads.
