Satellite Time-Lapse Imagery

Google Earth put images from LandSat satellites together to create time-lapse images of our changing Earth. You can see how some places have changed dramatically over the past 30 years, such as the Amazon, where agricultural plots and towns are carved out of the rainforest (shown here); Las vegas as it grows; retreating glaciers; the Aral Sea drying up; and Saudi Arabia, where irrigation is making farms bloom.

Now that was cool. I wish I can do sky diving one day. :(

Docking in mid-air is one of the last skills a skydiver learns on the way to receiving his "A" license. I had to repeat that lesson four times before I finally got it. I've been working on it with a friend of mine who's roughly the same skill level (most definitely not an instructor) for a couple of weeks and finally succeeded.

This is a really neat trick. As for the motivation--does "because it was there" still count for anything?

Jason is talking about docking with another skydiver in freefall, obviously. That's a fundamental part of sport skydiving. Docking with a plane is not.

For anyone interested, I have some examples of freefall docking here, and you can see the original plane-chasing experiments and other nutty skydiving business on Joe Jennings' DVD "Good Stuff" at JoeJennings.com.
