JunoCam is a special camera, sitting aboard NASA's Juno spacecraft, that requires the public to contribute to virtual imaging work having to do with the planet Jupiter.
The JunoCam is going to be capable of imaging Jupiter in the highest resolution ever achieved, and will represent a significant improvement over previous kinds of cameras. The public will be asked to help decide which regions of the massive gaseous planet the camera should focus on via a voting system.
Broadly speaking, the JunoCam initiative enables people -- particularly young people -- to feel like they are a part of humanity's space exploration missions. It's only the latest example of how NASA is leading the way in terms of public engagement, something that science-based businesses would do well to emulate.
