ESA has published images of the area of the planet Mars known as Libya Montes taken by its Mars Express space probe. It’s a mountain range near the Martian equator and is one of the oldest in Mars, altered by volcanic processes and impacts but also by processes associated with the existence of rivers. In the pictures it’s possible to identify various channels and valleys, traces of the ancient water streams.

ESA has released new images of a crater with a diameter of about 70 kilometers in the region of the planet Mars called Margaritifer Terra. This is a composite of two images captured by the Mars Express Space space probe’s High Resolution Stereo Camera (HRSC) instrument almost exactly 10 years away in March 2007 and February 2017. The crater and the surrounding area show yet again evidence of the presence of liquid water in Mars’ distant past.

NASA started publishing the first photos taken by the Cassini space probe after its descent into the gap between the planet Saturn and its rings. These are the closest photos taken during a risky maneuver for Cassini, performed only because within a few months it will end its mission so it was decided that it’s worth taking risks to collect close-range data.
