TGO

Having measured HCl and water ice abundance in Martian atmosphere with the ACS spectrometer onboard TGO mission, scientists showed that it is HCl uptake onto water ice cloud particles that can swiftly reduce the content of HCl in the atmosphere.

Using data from ACS spectrometer onboard TGO spacecraft, IKI scientist Ekaterina Starichenko and her colleagues studied gravity waves in Martian atmosphere, from the surface to the 160-km height, and the effect, which seasonal changes and dust storms have upon them. Results were published in the Astronomy&Astrophysics.

On 20th May 2024 IKI instuments, working near the Red Planet, caught it and stayed safe.

Atmospheric Chemistry Suite, the Russian instrument onboard ExoMars TGO orbiter, found that carbon monoxide in Martian atmosphere yields less heavy carbon isotopes 13C than 'light" 12C. Results of the study have been recently published in Nature Astronomy.
