Aeolus new special settings

"Starting today, Aeolus will be measuring stratospheric aerosol layers caused by the recent Australian bushfires using new special vertical range bin settings. It will be the first time aerosol particles and Mie winds will be measured by Aeolus from an altitude of up to 29 km", ESA announced today in a twitter thread on Aeolus' official account.

Australian bushfires' smoke detected in Chile

ESA also gives us more insight about the global impact of the Australian wildfires, with smoke detected by station in Chile as an example.

Smoke from the bushfires traveled around the globe and was detected by the Aeolus Cal/Val station at Punta Arenas in Chile. The new measurement will allow experts to determine the speed of the smoke plume and assess Aeolus’ capacity to measure aerosol in high altitudes.

This remarkable image was taken in the Terra Sabaea region of Mars, west of Augakuh Vallis, by the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ESA-Roscosmos ExoMars Trace Gas Orbiter. This mysterious pattern sits on the crest of a ridge, and is thought to be the result of dust devil activity – essentially the convergence of hundreds or maybe even thousands of smaller martian tornadoes.

This image is a colour-composite representation where features that are bluer compared to the average colour of Mars are shown in bright blue hues. In actual colour, the streaks would appear dark red. Dust devils churn up the surface material, exposing fresher material below.

The reason why the streaks are so concentrated on the ridges is not known at present, but a relationship to orographic lift as masses of carbon dioxide air flow uphill and converge with other air masses is one possibility.

The image was taken on 8 February 2019 and is centred at 26.36ºN/56.96ºE. North is up.

Luca was launched to the International Space Station for his second mission, Beyond, on 20 July 2019. He will spend six months living and working on the orbital outpost where he will support more than 50 European experiments and more than 200 international experiments in space.

Follow Luca and his Beyond mission on Twitter or Facebook on his website and on his blog.
