The EnMAP Mission: Foundation for new scientific research and application - Sabine Chabrillat

Prof. Sabine Chabrillat GFZ Potsdam @GFZvideos @HelmholtzTV Helmholtz Center Potsdam GFZ German Research Center for Geosciences, Potsdam, Germany and Leibniz University Hannover (LUH), Institute of Soil Science, Hannover, Germany On April 1, 2022, EnMAP, the first hyperspectral satellite built and developed in Germany, was launched into space aboard a Falcon 9 rocket from Cape Canaveral, Florida, by the US aerospace company SpaceX. The mission is managed by the German Aerospace Center (DLR) in Bonn on behalf of the Federal Ministry for Economic Affairs and Climate Action (BMWK). OHB-System AG was commissioned to develop and build the satellite and the hyperspectral instrument, while the ground segment is being developed and operated by DLR in Oberpfaffenhofen. The mission is under the scientific coordination of the German Research Centre for Geosciences (GFZ) in Potsdam. On April 1, 2022, the mission is under the scientific coordination of the GFZ German Research Centre for Geosciences in Potsdam. ... The environmental satellite EnMAP (Environmental Mapping and Analysis Program) will map the state of the Earth's surface using imaging spectroscopy. EnMAP's primary scientific objectives are to investigate environmental changes, study ecosystem responses to human activities, and monitor natural resource management. The satellite will provide a continuous spectrum across 224 spectral bands from 420 nm to 2450 nm, with average spectral sampling of 6.5 nm (VNIR) and 10 nm (SWIR). Crucial to EnMAP's scientific goals are high-quality spectral data, a spatial resolution of 30 m, a 27-day repetition interval at the nadir, and a 4-day repetition interval with a 30° tilt outside the nadir, which can be used to monitor dynamic events. After the commissioning phase, EnMAP data will be made freely available to the international user community. ``` Imaging spectroscopy enables the identification and quantification of surfaces based on their spectral characteristics. The EnMAP mission represents a milestone in imaging spectroscopy for several reasons. The unprecedentedly high data quality is ensured by precise onboard calibrations, which allow for an accuracy in quantifying surface properties previously unattainable from space. Furthermore, the mission is characterized by intensive scientific preparation for data use, including the development of evaluation algorithms, aerial surveys, doctoral student training, and online courses, all aimed at enabling the user community to make the best possible use of the data. The diverse applications of EnMAP data range from exploration of mineral deposits and soil mapping to monitoring water quality, early detection of plant stress, and the assessment of pollution. EnMAP will provide crucial data for accurately determining the consequences of climate change and other environmental changes on Earth. This presentation provides an up-to-date overview of the development of the EnMAP satellite, its current mission status, and the scientific research expected. Videos from #WiKoRaumfahrt 2022 The first German science conference was a great success! With a diverse program of keynote speeches, lecture sessions, and panel discussions, all participants had ample opportunity for a lively exchange of information about space science "Made in Germany."
