The announcement yesterday (Jan 31 2001) that the solar wind may have stripped off the early Martian atmosphere when the Martian magnetic field died and Mars lost its protective magnetosphere implies that, as a follow- on consequence, humans' potential attempts to terraform Mars by producing an earthlike atmosphere may suffer a similar fate. How seriously does this finding hurt the chances of terraforming Mars? Will humans be able to restart the internal Martian dynamo to resurrect the Martian areomagnetic field? Could any other process protect an atmosphere from the solar wind? Or does this finding imply that Martian colonists will necessarily be confined to domed/tented communities, and that a renascent Martian atmosphere is impossible?
