What is Mars research for anyway? Harel Dor at NASA Jet Propulsion Laboratory explains how the tools we developed to study space also help us understand Earth. #Mars #Space #NASAJPL #SpaceExploration | Museum of Science, Boston

Mars lies an average of 225 million kilometres from Earth. Its surface is a cold, dusty desert with towering volcanoes, giant canyons, rocky plains, and unusual rock formations. Ancient riverbeds show that water once flowed here, raising the possibility that life might have existed on the Red Planet long ago. Every rover and orbiter sent there helps us uncover more secrets of this distant world. #NASA #mars #SpaceX | Space Journey
