Exploratour - The Magnetosphere of Mars
Results and Conclusion
Recently, Mars Pathfinder returned a measurement which suggested that Mars has a large iron core. And there definitely is a magnetic field generated inside the planet as the Mars Global Surveyor measurement shows.
The presence of a magnetosphere helps scientists understand more about the interior of Mars and how Mars evolved. At this point, many questions still remain about the Martian magnetosphere. With further missions to Mars, we will certainly be able to investigate the magnetosphere of the Red Planet.
