This project is solving the Reach For the Stars challenge.

This website/application combo introduces you to Moon Bounce communications or Earth-Moon-Earth, EME, bouncing radio signals off the moon! The activity enables you to encode and decode Slow Scan Television images, store and retrieve content for later transmission to the moon and back.
It uses application software for the Iphone, which decodes the audio tones of a Slow Scan Image Transmission, into an image on the Iphone Screen. This is an enhancement to existing MMSSTV software which does this on a PC, and makes Image Bounce, a special form of Moonbounce accessible to many in STEM Projects.

Also planned is an overview of how to make a Scientific Measurement of the distance to the moon, using Moonbounce, and to check your calculated distance against a NASA Gold Standard, a Moon Ephemeris on line, with precision distances to the moon for any date and time.
The distance measurement experiment is done by measuring the round trip time of the radio signal between the Earth and the Moon, about 2.5 seconds, varying above and below, depending on whether the moon is at Apogee, Perigee, or somewhere in between.

This application is designed to stimulate interest in space and STEAM (Science, Technology, Engineering, Arts and Mathematics). An Enhancement of the more commonly known Acronym, STEM.
