Economical snapshot of earth's curvature
Cognitive geneticist Dr. John Fossella points out this story...4 teens in Spain sent a weather balloon to the edge of space...20 miles up and snapped pictures of the earth with a $120 camera.
Here's the story....here's the photostream
Just imagine if there was a way to carry a model rocket engine as payload (one or more) and ignite them via radio signal...achieving the cheapest ever geosycnchronous orbit for an object..could be an action figure in a space suit. Bypass earth's gravitational cocoon and you would have your own interplanetary (and interstellar) probe, on the cheap.
