Role of Inner Planets Panel (IPP)

•  Develop/refine Goals and Objectives for exploration of the Inner Solar System

•  Identify interconnections to other solar system objects and extrasolar planets

•  Role and relative value of human exploration •  Supporting research and related activities (NASA and

NSF) – R&A, theory/modeling, computing, data distribution/analysis/archiving, E&PO

•  Instrument and infrastructure, including: curation, technology development, telescopes

•  International interconnections •  Recommendations to steering group: identify potential

missions for Inner Solar System exploration and prioritize them (Flagship, NF, balance of missions)

3rd Meeting: Inner Planets Panel April 21-23, 2010, Boulder CO

Agenda: TBD

IPP Science Themes

1) Understand the origin and diversity of terrestrial planets.

2) Understand how the evolution of terrestrial planets enables and limits the origin and evolution of life.

3) Understand climate change on Earth-like planets.

White Papers

35 Moon-focused 9 Venus –focused 0 Mercury-focused 2 relevant to all three inner planets 32 general topic papers submitted to multiple

panels Total of 78 papers

During second IPP meeting all white papers presented by panel members and discussed in detail.

Examples of White Papers

Exploration concepts: (1) The Lunar Exploration Roadmap. Exploring the Moon in the 21st

Century: Themes, Goals, Objectives, Investigations, and Priorities, 2009.

(2) The Scientific Rationale for Renewed Human Exploration of the Moon. (3) Summary and Highlights of the NRC 2007 Report: The Scientific

Context for the Exploration of the Moon.

Mission concepts: (1) Constraining Solar System impact history and evolution of the

terrestrial planets with exploration of and samples from the Moon’s South Pole-Aitken Basin.

(2) Lunar Polar Volatiles and Associated Processes. (3) Sampling the age extremes of lunar volcanism: The youngest and

oldest lunar basalts.

Examples of White Papers

Science concepts: (1) Importance of Measurements of Charging Properties of Individual

Submicron Size Lunar Dust Grains. (2) Solar Radiation Output: Reading the Record of Lunar Rocks. (3) Determining the Origins of Lunar Remanent Crustal Magnetism . (4) Lunar Pyroclastic Deposits and the Origin of the Moon.

Technology investments: (1) On Lunar Volatiles and Their Importance to Resource Utilization and

Lunar Science . (2) A Survey of Technologies Necessary for the Next Decade of Small

Body and Planetary Exploration . (3) Developing Sample Return Technology using

the Earth's Moon as a Testing Ground (4) Development of Capabilities and Instrumentation for Curation and

Analysis of Returned Samples.

Mission Planning New Frontiers and Flagship

3 teams: Moon, Venus, Mercury -  Review previous decadal survey plus other planning documents (NRC,

NASA, etc.) -  Update for recent missions, new science, new technologies

(worldwide) -  Review White Papers and Presentations to Panel -  Recommend mission studies: Rapid Mission Architecture (RMA)

Studies, Full Mission Studies, Independent Cost Estimates

Lunar Missions discussed -  Sample return missions -  Geophysical network - Exploration of polar deposits

1 round already, to be announced at DPS. From IPP: -  Mercury lander mission (RMA) -  Venus near-surface mobile explorer mission (RMA)
