Abstract

Images from the Mars Orbiter Camera on the Mars Global Surveyor spacecraft show crater populations extending the size distribution down to around 16 m. The results suggest a broad range of surface ages. Lava flows within the Arsia Mons caldera are estimated to be no more than 40-100 million years old, and it is suggested that on Mars, volcanism is a continuing process.
