2. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  Mariner 4: 1964 flyby mission  So much for a nice, Earthlike planet  Magnetometer showed no magnetic field (team thought instrument buggy)  Occultation of spacecraft by Mars showed a really thin atmosphere  First image showed a cloud, thought impossible and a lens crack  Craters up the wazoo: Mars looked like the Moon  First topographic maps

3. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  Mariner 4: 1964 flyby  So much for a nice, Earthlike planet  Craters up the wazoo: Mars looked like the Moon  First topographic maps  One dead, bleak, battered planet

4. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  Mariner 6 and 7: 1969 flyby mission and first dual mission  Again, Mars is pretty disappointing  Both S/C flew over heavily cratered terrain  They both missed the big volcanoes and Valles Marineris  Dark areas were no canals  Dead, dry Mars

6. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  USSR Mars 4  S/C fails orbit insertion and becomes unintended flyby  It does return some pictures  Dead, dry Mars

7. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  NASA Mariner 9  First successful orbiter  Active for ~1 year  Arrived during huge global dust storm  Saw Olympus Mons emerge from the dust  Photomapped 100% of Mars

8. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  NASA Mariner 9  First successful orbiter  First glimpse of possible river valleys

10. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  USSR Mars 5 orbiter  Failure in orbit insertion  It did send back several images

11. C.M. Rodrigue, 2007 Geography, CSULB Mars: Data from Robotic Missions  USSR Mars 5 orbiter  Failure in orbit insertion  It did send back several images
