Plate tectonics on Mars?
Article Abstract:
The first observations of martian magnetic anomalies have been reported, made with magnetometers on the Mars Global Surveyor spacecraft. Connerney and colleagues argue that the satellite tracks could have been produced by early plate motions. They note that they need an intensity of magnetization greater than that of the largest magnetic anomaly on Earth. A crust of around 20 km thick is adequate to generated the observed magnetic anomalies, and Connerney and colleagues suggested that iron sulphides are needed as well.

Pathfinder probes the weather on Mars
Article Abstract:
NASA is resting the Pathfinder Mars probe at night after using the vehicle to explore the surface of the planet for more than one month. The move will hopefully keep the lander operational for a few more months using solar power. It will also reduce the charging and discharging activities which drains Pathfinder's batteries. In recent weeks, scientific attention has focused on the lander's data involving the Martian weather.
