Fifty years ago this month, the Mariner 9 mission became the first spacecraft to orbit another planet beyond Earth. It created the first global map of Mars and set the course for Martian exploration for the next five decades. Dr. William K Hartmann was a co-investigator on the mission and wrote the book The New Mars: Discoveries of Mariner 9, and he joins Jake to talk about the impact this mission has, even today.We talk Mariner 9NSSDC Profile for Mariner 9Follow BillBill's Profile at Planetary Science InstituteBill's space-inspired paintingsFollow Jake & WeMartiansWeMartians.comPatreon (https://www.wemartians.com/support)WeMartians Shop (shop.wemartians.com)Mailing List (https://wemartians.com/signup)Twitter (@we_martians)Jake’s Twitter (@JakeOnOrbit)Off-Nominal PodcastMarsti.meMarsti.meLearn about time on Mars!
