Via Colony Worlds comes the news that Tom and Tina Sjogren, a dedicated pair of adventurers, have announced their intent to head to Mars in the year 2014. The Sjogrens are experienced and hardy types, having climbed Everest and visited the South Pole twice (under their own steam and unsupported), and have apparently made serious and detailed plans as to how they intend to go about this incredible undertaking. I’d love to see them succeed, but there are so many factors to overcome that it seems a long shot at best. But who knows? Maybe the molten core of Mars will have started to generate a magnetic field by then.
