On November 19, 2022 (late-winter in the northern hemisphere), images from the EMM/EXI camera system revealed the fully-developed winter expanse of the North Polar Cap (formed by surface deposits of frost and ice composed of frozen carbon-dioxide and water).

Bands of bluish water-ice clouds surround the polar cap. The northern extent of the dark surface feature Acidalia Planitia was visible through a large gap in the clouds (near image center)

يتدفق عمود سحابي يبلغ طوله أكثر من 1500 كيلومتر غربًا من بركان ثارسيس أرسيا مونس (يبلغ ارتفاعه حوالي 20 كيلومترًا). A more than 1500 km long cloud plume streams westward from the Tharsis volcano Arsia Mons (itself nearly 20 km high).

Understanding Martian water ice clouds is key to studying the planet's climate. A new study, the first between EMM & ESA’s TGO, reveals how cloud vertical profiles impact data accuracy across latitudes. Learn more in the paper by Aurélien Stcherbinine et al.

To retrieve cloud optical depth from nadir observations, scientists often assume a uniform cloud profile. However, with multiple probes observing Mars from different angles, more precise cloud property retrievals are possible.

From crustal-field auroras to proton auroras, the Red Planet continues to amaze. Read more here: pubs.aip.org/physicstoday/ar… Stay connected with the Emirates Mars Mission as we journey further into the mysteries of Mars.

A menagerie of Martian auroras

The red planet’s auroral activity stems from processes that are not seen on Earth.

Geo maps show aurora occurrence on Mars from EMM EMUS data. Aurora is frequent in strong vertical crustal field regions and very weak ones with open magnetic topology (field lines connected to the collisional atmosphere).

The Emirates Mars Ultraviolet Spectrometer (EMUS) has observed Martian nightside auroras in far UV wavelengths. Two Mars years of data reveal dependencies on crustal field, magnetic topology, local time, and season, enhancing our understanding of Mars' magnetic environment.

The figure shows variability in average emission intensity profiles of H Lyman emissions across Martian seasons. There's a notable increase in H Ly-γ and Ly-β emissions during the southern summer solstice and dust storms. More in the JGR Space Physics paper by Raghuram Susarla.
