Company DeskSiemens has opened an Egyptian manufacturing facility with a customer technology centre and Power Academy, following its earlier agreement to localise electrical production.
PerspectivesTwo small satellites compare direct and reflected navigation signals to study soil, wetlands, frozen ground and vegetation. Their measurements pass through calibration and specialised scientific processing.
PerspectivesCeltic’s construction links cable factories, coastal works and converter stations in Ireland and France. Dated milestones track installation, equipment preparation and community funding.
PerspectivesIMAP combines neutral-atom imagers, particle instruments, magnetic measurements and dust analysis. Its integration tests, flight operations and dated data releases trace the path from individual instruments to a working observatory.
PerspectivesAriel links a cold infrared payload with the preparation of future exoplanet observations. Structural tests, instrument electronics, cooling and simulated data each have their own development stages.
