HiRISE PICTURE OF THE DAY: 16 JULY 2025
Bright Patches in Terra Sirenum
This observation is a good example of when different missions work together: the CaSSIS instrument on the ExoMars Trace Gas Orbiter identified here 10-meter scale bright patches on irregular collapse feature rims. An example of a location with possible mud volcanism? An image at HiRISE resolution can help to answer that question.
