HiPOD 21 Jan 2019: Contours

The objective of this observation is to search for layers in the northern ice cap. And also to marvel at the contours that were centuries in the making.

HiPOD 22 Jan 2019: Chain of Craters

The terrain here looks like it took many serious lashings. Could any of these impacts be secondary craters?

We’ve been studying #Mars for more than 15 years with Mars Express. Now ExoMars @ESA_TGO is sniffing for gases and sending images like this: an ancient river delta that once carried liquid water across the planet’s surface! #ScienceAtESA
