M.I.T. students launch $150 space camera
You don't always need an expensive professional dSLR to capture awe-inspiring images. Sometimes, a basic Canon A470 point and shoot, a little ingenuity, and a beer cooler are all you need. That is what two M.I.T. students used to capture images of the Earth from space, well, actually the upper atmosphere; technically, it wasn't high enough to be space.
Justin Lee and Oliver Yeh, M.I.T. students, had a goal of flying a camera high enough to photograph the curvature of the earth, they named it Project Icarus. With out having a NASA size budget for a rocket, they opted for the more cost effective method of filling a weather balloon with helium and suspending a Styrofoam cooler underneath that held the camera. They also placed some instant hand warmers inside the cooler to try to keep the camera and its battery from freezing.
