Pathfinder's rover was a toy-size machine. Barely 1 ft. high and 2 ft. long and weighing 24 lbs., it operated for three months and in all that time toddled across a stretch of Martian terrain little bigger than a football field.

Barely 30 cm high and 60 cm long and weighing just under 11 kg, it operated for three months and in all that time toddled across a stretch of Martian terrain little bigger than a football field.

But I had prepared for 16 years, learning to feel my way up mountainous terrain using ice axes and long poles. I finally concluded that when other people's expectations become barriers, the best thing to do is to surmount them...
...albums. Using touch-screen monitors mounted on the back of each seat, travelers will also be able to surf 24 channels of live satellite TV, challenge their seatmates to multiplayer video games from Nintendo and map the airplane's exact location--zooming in to street-level detail on the terrain below...
