Aeolus set for Instrument Telescope Refocussing exercise

Aeolus’s telescope requires periodic collimation and refocussing. To this end, the Instrument Telescope Refocussing activity aims to improve the radiometric performance of the Atmospheric Laser Doppler Instrument (ALADIN)’s telescope by optimizing the throughput at the field stop, the smallest aperture where the return light has to pass. This is done through a change of the temperature settings on the telescope.

Around the world in eight balloons with Strateole-2

Strateole-2 is a French-US project supported by ESA that uses CNES superpressure balloons drifting around the globe to study the climate processes in the Tropical Tropopause Layer (TTL) and the lower stratosphere, helping Aeolus validation activities along the way.

scientific highlights

Heritage data still widely used today

For about 30 years now, ESA satellites have been cruising some 800 km above our heads, collecting information about our planet-but why are older missions still so fundamental today?
