Deep 'scratches' and craters on Mars tell the tale of a Red Planet ice age

Recent images captured by the Mars Express orbiter have revealed significant evidence of a past ice age on Mars, particularly in the planet's mid-latitudes. These findings provide insight into the dynamic climate history of Mars, suggesting that the planet has undergone substantial climatic changes over time. The deep scratches and craters observed in the images are indicative of this historical ice age, marking a crucial development in understanding Mars's geological and climatic evolution.
