I am currently reading Father and son launch iPhone into space.
As I think back to all of the fun things that my father and I did together when I was a kid, numerous Cub Scout activities come to mind such as the Pinewood Derby, but one particular favorite was launching model rockets. I remember wishing that there was a way that my rocket could go all the way up into space.
Fast forward about 30 years and Luke Geissbühler of Brooklyn, NY, who works by day as a Director of Photography on films, worked with his seven year old son Max — and other friends in a group he founded called the Brooklyn Space Program — to launch a homemade spacecraft all the way into the upper stratosphere. The contraption he built would need to be able to survive 100 mph winds, extreme cold temperatures, and a drop from 19 miles high at over 150 mph. It took eight months to design, but less than $500 to build. And it worked. I realize that this is the little boy in me talking, but oh-my-goodness what an an amazing father-son project!
How did he build it? He used a weather balloon to lift his 1.5 lb. spacecraft and a parachute to help it fall back to Earth. The spacecraft carried a GoPro Hero HD camera to record the flight. To keep track of the flight, he put inside the spacecraft an old iPhone 3G (that already had a cracked screen, donated by a friend) running the GPS Tracker app. [Click here for GPS Tracker (free): ] The GPS Tracker app sends information such as latitude, longitude, speed, and a timestamp every five seconds to the free InstaMapper website. Thus, during the flight, Geissbühler just had to view a page on the InstaMapper website to continuously monitor the iPhone as it ascended and descended and to locate the iPhone after it landed (in a tree). (Actually, the GPS could only pick up satellites below 50,000 feet, so for the second half of the flight he had to do some complex modeling to estimate the coordinates).
