ADM-Aeolus will gather data using the active Doppler Wind Lidar (DWL) method, whereby an active instrument emits laser pulses into the atmosphere and measures the Doppler shift of the collected return signal, backscattered at different levels in the atmosphere, creating a wind profile showing the relative strength of winds at different altitudes, as well as moisture and dust levels in the atmosphere.
Aeolus’ instrument is Aladin (Atmospheric LAser Doppler INstrument), a direct detection lidar incorporating a fringe-imaging receiver (analysing aerosol and cloud backscatter) and a double-edge receiver (analysing molecular backscatter). The mission is named after the mortal in Greek legend appointed by the gods as keeper of the winds.
Astrium is prime contractor for the Aeolus mission, and also responsible for the Aladin instrument, platform electrical architecture and subsystems.

The Aestus rocket engine powers the Ariane 5 ES and GS version bipropellant upper stage for the insertion of payloads into LEO, SSO and GTO. For the ES version, Aestus uses its re-ignition capability to place ESA's 21 tonne (ATV) into a low Earth orbit. Aestus is a pressure fed engine that consumes up to 10 tonnes of the b i p r o p e l l a n t c o m b i n a t i o n MMH/N2O4.
