Did Mars' Magnetic Field Die With a Whimper or a Bang?

Giant asteroids may have wiped out Mars's magnetic field. The energy released by massive collisions upset the heat flow in the planet's iron core that produced the magnetism, according to a new study. The finding offers a solution to the mystery of the disappearing magnetic field and sheds light on early Earth conditions.

Webmaster's Commentary: 

Even during the Viking Missions, the subjective consensus was that we were looking at the remains of a dead world, one that had once had, water, once had more atmosphere, once had life.

The Hella Planitia region is an obvious impact feature, and what is interesting is the antipode of that monster impact is the obviously elevated and fractured Tharsis/Valles Marineris region, suggesting that the impact almost punched its way completely through the planet! Such a deep impact would disrupt the normal internal convection currants that generate a magnetic field, and without that field, the solar wind would over millions of years strip away whatever was left of the atmosphere of Mars after the impact.
