Gregory Nemitz, President of Orbital Development, told CNN that the project might be "attractive to some bored rich guy who's tired of playing with his radio-controlled model airplanes and wants to move up to the next level." In addition, the company would return digital photos of the lunar journey and the impact as part of the project.
