Project Introduction

Planetary Instrument Definition and Development Program (PIDDP)

The Planetary Instrument Definition and Development Program (PIDDP) supports the advancement of spacecraft-based instrument technology that shows promise for use in scientific investigations on future planetary missions. The goal is to define and develop scientific instruments or components of such instruments to the point where the instruments may be proposed in response to future announcements of flight opportunity without additional extensive technology development.

Results of PIDDP have contributed to the development of flight hardware flown on, or selected for, many of NASA's planetary missions. The instrument technology selected through PIDDP addresses specific scientific objectives of likely future science missions. Instrument definition and development studies take place at several stages, including feasibility studies, conceptual design, laboratory breadboarding, brassboarding, and testing of critical components and complete instruments. The technology readiness level (TRL) that PIDDP supports is TRL 1-6. For immature or particularly complex new instruments, proposers initially may choose to only define or develop the most risky components. When the proposed effort is for a component only, the proposed effort describes one or more likely scenarios for possible follow-on instrument development. Scientific objectives of the instruments, proposed follow-on instruments, and future candidate missions are discussed in the proposal for each selected activity. It is the responsibility of the proposer to demonstrate how their proposed instruments address significant scientific questions relevant to stated NASA goals and not for NASA to attempt to infer this.
