We plan to discover how to build the mechanical systems needed to We plan to discover how to build the mechanical systems needed to extend a platform with a cluster of mirrors on the end. This mission extend a platform with a cluster of mirrors on the end. This mission will hopefully give us the ability to learn about the near space will hopefully give us the ability to learn about the near space environment and many new technological skills involving the environment and many new technological skills involving the mechanical platform deployment. The mission will also help us mechanical platform deployment. The mission will also help us discover how to retrieve the mechanical platform back into the discover how to retrieve the mechanical platform back into the satellite before landing in order to keep the mirror from being satellite before landing in order to keep the mirror from being damaged.damaged.

We are doing this mission for the challenge of the extendable arm and We are doing this mission for the challenge of the extendable arm and the possibility of better images of stars.the possibility of better images of stars.
