EnMAP (Environmental Mapping and Analysis Program) is a high-resolution imaging spectroscopy remote sensing mission that was successfully launched on April 1st, 2022. Equipped with a prism-based dual-spectrometer, EnMAP performs observations in the spectral range between 418.2nm and 2445.5nm with 224 bands and a high radiometric and spectral accuracy and stability. EnMAP products, with a ground instantaneous field-of-view of 30m×30m at a swath width of 30km, allow for the qualitative and quantitative analysis of surface variables from frequently and consistently acquired observations on a global scale. This article presents the EnMAP mission and details the activities and results of the Launch and Early Orbit and Commissioning Phases until November 1st, 2022. The mission capabilities and expected performances for the operational Routine Phase are provided for existing and future EnMAP users. •EnMAP launched on April 1, 2022, and entered routine operations on November 2, 2022.•Satellite checked out and cycle of acquisition planning to product delivery confirmed.•In-flight spectral, radiometric and geometric calibrations performed and analyzed.•Fully-automatic image processing chain for three user product levels released.•Quality assessment and product validation of imaging spectroscopy data conducted.
