argument asked british climb compelling everest famous george million mission mount reason reply rover trying
The British mountaineer George Mallory was once famously asked why he was trying to climb Mount Everest and his famous reply was 'because it is there.' That's a compelling argument when you are a mountaineer. But for an $850 million rover mission you better have a better reason than that.

Chris will remember vividly as we were struggling along the northwestern flank of that mountain how much loose, fine-grain stuff there was. Our wheels would dig in, we'd slip around and we'd dig in deep. Remember that potato-sized rock we got stuck in the wheel once?
