The James Webb Space Telescope captured its first images and spectra of Mars on September 5, 2022. The telescope’s remarkable infrared sensitivity provides a unique perspective on our neighboring planet, complementing data collected by orbiters, rovers, and other telescopes.
Because it is so close, the Red Planet is one of the brightest objects in the night sky in terms of both visible light (which human eyes can see) and the infrared light that Webb is designed to detect. This poses special challenges to the facility, which was built to detect the extremely faint light of the most distant galaxies in the universe. Webb’s instruments are so sensitive that without special observing techniques, the bright infrared light from Mars is saturating the detector.
The final programme of the EPSC 2022 has been announced. In particular the schedule of the RoadMap session “Martian dust and clouds: from lab to space” (TP6) is now known: two oral sessions will take place on Tuesday 20 Sept. (15:30-16:55) and Wednesday 21 Sept. (10:00-11:30) and posters will be on show on Monday 19 Sept. (18:45-20:15).

The RoadMap project, its teams and their research are represented at the ExoMars exhibition of the (Flemish) Astropolis Space Science Center in Ostend, Belgium. The exhibition is centered around ESA's Mars missions and wil be open to the public from April 1 until October 31, 2022.

The session “Martian dust and clouds: from lab to space” (TP6) proposed by the RoadMap consortium, has been officially accepted by the Europlanet Science Congress organizers. EPSC will be held in Granada (Spain) from 18 to 23 September 2022.
Martian dust and clouds: from lab to space
Dust and clouds are critical elements in the Martian atmosphere. They control the radiative budget, have an impact on the composition, and affect its dynamical processes.
The aim of this session is to bring together scientists involved in modelling and observing Martian dust and clouds, from the lab to the analysis of space data. We will consider presentations on observations, field and laboratory experiments covering different aspects of dust and clouds, such as aeolian processes, dust lifting, sedimentation, scavenging, nucleation, aggregation, optical properties including scattering characterization, etc., but also on modelling of these processes from the perspective of implementation in radiative transfer codes or Global Circulation models.
