In the webcam view, that massive dome-like structure houses our satellite dish. So, for the webcam image to reach you, it's got to whizz through there first, and up to a satellite in space, then bouncing back down and around the Internet. Crazy stuff.

The two black pipes on either side are the smoke-stacks from the engines, and the two orange things just inside them are the two big inflatable boats. The two white things pointing in towards the dome are the cranes. The heli-deck is just visible in the background, and the yellow vertical thing in the foreground is an antenna (the mast is festooned with the things).

Through the course of this trip, and throughout the year, we'll be experimenting further with the webcam. So all ideas and suggestions (within reason!) - are welcome. Post them below!

In the meantime, here's some photographs of this morning's high-altitude expedition.
