WORKSHOP CONTENTS: LUNAR ORBIT CUBESAT MISSION AND LUNAR SURFACE
ROVER MISSION.
UNISEC Global is pleased to announce the 9th Mission Idea Contest Preliminary
Workshop seeking exciting ideas for lunar orbit and rover missions. These lunar mission
ideas will be presented at the workshop for discussion and development with theassistance of experts.
The lunar missions consider the use of one or more CubeSats placed into lunar orbit orone or more rovers deployed on the lunar surface. Designs are encouraged todemonstrate originality, impact, engineering elegance, and feasibility.
The requirements presented in this document are the top-level driving mission
requirements for mission designers in order to specify and design either a:•Lunar Orbit CubeSat Mission (LOCM) - Section 3; or•Lunar Surface Rover Mission (LSRM) - Section 4.
