First processed images from DESIS hyperspectral Earth observation instrument
02 October 2018
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), and Teledyne Brown Engineering presented the first images of the DESIS hyperspectral Earth observation instrument at the International Astronautical Congress (IAC). The instrument was mounted to the exterior of the International Space Station on 27 August 2018.
DESIS, the DLR Earth Sensing Imaging Spectrometer, has the highest performance of any hyperspectral Earth observation instrument in space. From its 400 kilometre-high orbit on the International Space Station ISS, this instrument acquires image data on 235 closely spaced spectral channels with a ground resolution of 30 metres. This data is making it possible for scientists to gain very precise details of changes to Earth's ecosystems. For example, they can use the information obtained to assess the health condition of forests or agricultural areas, and take such assessments as the basis for yield forecasts. They can also use this data to monitor environmental problems, thus providing the basis for devising measures to protect the environment and resources.
