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).

We are pleased to host 11 posters and 14 talks, inluding the folowing sollicited ones

  • Spectropolarimetry of Mars: Why and how?, Daphne Stam
  • The diurnal and seasonal variation of dust observed by the Perseverance rover and Emirates Mars Mission, Michael Smith, Khalid Badri, Samuel Atwood, Germán Martínez, Eduardo Sebastián, Victor Apéstigue, Ignacio Arruego, Daniel Toledo, Daniel Viúdez, Jose Antonio Manfredi, Christopher Edwards, Nathan Smith, Christopher Wolfe, Michael Wolff, Philip Christensen, Saadat Anwar, Mark Lemmon, Eman AlTunaiji, and Manuel de la Torre
  • A lower-than-expected saltation threshold at Martian pressure and below, Philippe Claudin, Bruno Andreotti, Jens Jacob Iversen, Jonathan P Merrison, and Keld Romer Rasmussen
  • Retrieving scattering properties of Martian dust analogues by modelling light scattering, Julia Martikainen, Olga Muñoz, Teresa Jardiel, Marco Peiteado, Juan Carlos Gómez Martín, and the RoadMap Team

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.

RoadMap partners presented their advances at the 7th Mars Atmosphere Modelling and Observations (MAMO) workshop, which was held in Paris, France from June 14 to 17.
We had several talks and posters showing the results obtained so far.
