Editor's 12:00 am note: Scott Parazynski checked in a few minutes ago at Everest Base Camp using his SPOT Satellite Personal Tracker. After settling in we should start to get a lot more from Scott via a BGAN (INMARSAT satellite) phone. You can track Scott's progress here and on Twitter. You can see the path he took (and the one I will take in a week or so) here.
Editor's update: More updates just in from Scott at Everest Base Camp:
