Mars minerology points to cold, icy ancient climate
The climate throughout Mars’ early history has long been debated – was the Red Planet warm and wet, or cold and icy? New research published in Icarus provides evidence for the latter. Mars is littered with valley networks, deltas and … Continue reading

Is underground the best place to look for origin of Mars life?
The planet Mars has long drawn interest from scientists and non-scientists as a possible place to search for evidence of life beyond Earth because the surface contains numerous familiar features such as dried river channels and dried lake beds that … Continue reading
Curiosity: Looking into the Phyllosilicate Trough
Sol 1949, January 29, 2018. The rover’s Navcam shot a composite that looks down into the low-lying area behind Vera Rubin Ridge. This is known as the Clay Unit or the Phyllosilicate Trough because clay minerals have been detected there … Continue reading
