The first images of Mars captured by the James Webb Space Telescope on September 5, 2022, offer views of the planet at different infrared wavelengths and some spectroscopies. Webb is in a position where it can see part of the sunlit side of Mars and can provide images and spectra to help complete the detections of space probes, rovers, and other telescopes. The red planet is very close and very bright compared to the normal targets of Webb’s observations, so the exposures used were very short to avoid causing problems to the instruments.
