Scientific paper

The specific scientific objectives of POLO are described and the experimental techniques required to meet these objectives are discussed. A basic payload for the orbiter is proposed. Tracking of the orbiter and the Relay and 'bent-pipe' tracking of the orbiter via the Relay as well as additional objectives, not necessarily related to lunar science, are also discussed. It is shown that the orbital requirements of the mission can be satisfied by means of an Ariane I launcher with a 4th stage. In order to satisfy the pointing requirements of the payload, a 3-axis stabilized orbiter is required. Subsystem concepts, making extensive use of design inheritance from current and future projects are presented. It is shown that a relatively simple spin-stabilized Relay spacecraft with conventional subsystems is adequate to support the tracking and payload requirements. It is proposed to use ground stations at Kourou and Odenwald for tracking and data acquisition. The state of development of the required scientific instruments is discussed, and technical management and schedule aspects are outlined.
