Episode 554 - Collaborating to solve Martian Mysteries

What caused those large quakes on Mars? How can Mars have big Mars-quakes without plate tectonics? If an impact crater isn't too blame for the Mars quakes what may be the cause. An international collaboration pooled the instruments of many countries Mars Missions to solve a mystery. Even using many different countries space ships, no 'smoking crater' was found that caused a mysterious martian quake. How can we study the ancient martian rivers and oceans using data from old martian missions? Jaroslav Klokočník, Gunther Kletetschka, Jan Kostelecký, Aleš Bezděk. Gravity aspects for Mars.
