PRIRODA, the last of the Mir modules launched on April 23, 1996, was designed for the Earth’s remote sensing. The experiments conducted by an international team supported a research program for the determination of atmosphere-ocean system characteristics and measurements of atmospheric optical characteristics. The vehicle also supported materials science, space technology, biotechnology and life sciences studies. Poland provided the digital camera that was a part of the scientific experiment ISTOK-IR spectroradiometer (wavelengths between 4.0-16.0 micrometer, 7km swath and 0.7 x 2.8km resolution).
