Genius! Not a mile from where I worked this summer, Cambridge University students earlier this month launched Nova 1, a meteorogical balloon juryrigged with a digital camera, GPS, mobile phone and radio transmitter. The thing went 32 km straight up and took 857 photos at 15-second intervals, some of which show some clear curves. it returned to Earth via parachute, landing 45 km due East a little under three hours later.
They’ve turned the positioning data into KML, though their link is a bit iffy. Here is a proper network link for it. The result looks like this:
What I’d really love to see is a time-enabled path with screen overlays for all 857 photos. It’d be trivial to do. I can’t wait for Nova 2.
