Other Launches
Several other groups have successfully launched balloons into the upper stratosphere and taken photographs of the earth from way up above (click on any of the links below to check out their launches). As far as we know, however, we are the first group ever to accomplish this feat on a budget of $150 and with off-the-shelf components available to the average layperson.
