Initial Mars Global Surveyor Findings
These are some of the initial findings of Mars Global Surveyor.
- There definitely is a magnetosphere near Mars.
- this finding suggests that scientists must rethink theories about the evolution of Mars.
- Surface features at Valles Marineris and elsewhere.
- suggests the importance of geologic processes such as erosion by wind and water
- Evidence of soil/atmosphere/water-cycle interactions somewhat like those of Earth.
- The altitudes of such features as Olympus Mons, the bluff separating the southern and northern hemispheres, and other features.
- More details about the Martian Atmosphere
These findings help address questions
which remain about Mars.
