9 OSEWG Surface Science Scenario Working Group Current Activities: Developing surface scenarios for individual lunar missions at different types of lunar sites: Phase 1: Exploration on the order of 7 days and 10 km radial distance from a landing site. Phase 2: Exploration on the order of 45 days and 100 km radial distance. Phase 3: Exploration on the order of 180 days and 1000 km distance. Developing overarching approach for metrics for evaluating likely scientific return from lunar missions and campaigns as measured against NAC lunar science objectives from Tempe Workshop as well as NRC SCEM Report Objectives 9

10 OSEWG SSSWG Conducted Phase 1 Workshop: Planning Sorties at Tsiolkovsky and Alphonsus Two groups of four scientists were tasked with Tsiolkovsky or Alphonsus craters and asked to design an exploration plan driven by scientific rationale. The exercise assumed a total of eight, two-man EVAs of eight hours, including the use of two unpressurized rovers Tsiolkovsky Alphonsus Results will be reported at NLSI Lunar Science Conference in July and folded into approach for longer surface stay scenario planning and metric development 10

16 ESMD Integrated Field Test, Moses Lake Washington, June 2008 A Record Setting Field Test: 7 Centers, 2 Directorates + 1 Univ. in the field Ground supervision of 3 robots (including incorporation of time delays) 8 Robotic systems at site >200 Hrs of experimentation >50 Kilometers driven >5km of night ops Most data collected (timelines, GPS ) Most alignment to architecture Most public participating at site Most integration of Lunar Science Lessons learned to be folded into HMP and October analog mission and field test activities 16

17 Moses Lake Field Testing of Science Operations Tasks: Identify visualization and science operation methods using the Apollo site survey baseline procedures and existing technologies for a science backroom Science Backroom: Use robotic rover to high grade a site: identify, triage, and prioritize science targets for follow-up human activity Obtain performance metrics of the ground control architecture s ability to effectively support science backroom operations Timeline baseline surface operations (i.e., sampling, tagging, etc.) Results: Current technologies and operational practices do not support real time science operations directed by the backroom. To perform a successful science operation, the science team has to coordinate and develop good pre-test science activity task planning. Exercises of this kind benefit from having at least one trained geologist among the crew to more fully exploit the significance of a site s geologic history and potential. Additionally, without a trained geologist among the crew, the back room is not exercised properly. It is difficult for a field observer to keep up with the extensive imagery and other information being analyzed and interpreted by many individuals manning the science back room. Forward Work: Complete collection, synthesis, and documentation of lessons-learned (in preparation for Oct field tests). Ensure site characterization data is available early enough to perform proper pre-mission planning (i.e., identifying sites of interest, laying out traverse paths, etc.). Identify exploration teams (including 2-3 geologists) that will be used over the next several years to validate operational concepts Incorporate the current visualization tools in the science backroom operations. 17

18 National Aeronautics and Space Administration Lunar Data Integration

19 Lunar Data Integration Activities & Plans Scientific Input to Landing Sites and Operational Decisions: The Lunar Reconnaissance Orbiter Camera (LROC) project of LRO has developed a target planning system to solicit, prioritize, and plan on-orbit operations to acquire exploration and science targets. Science targets will be solicited from the science community by the LROC project coordinated through the LRO project science office. A workshop will be planned to consolidate and prioritize the targets. The LPRP Lunar Mapping and Modeling Project (LMMP) is working with Constellation to identify required characteristics of exploration targets, i.e. geometry, landing hazard assessment, slopes, lighting, etc. This information will inform the development of the LMMP and be used as screening criteria for the selection and prioritization of potential landing sites. An OSEWG/LMMP sponsored LRO/LROC targeting workshop with Constellation will be held in October to integrate science and exploration targeting needs. 19

20 Lunar Data Integration Activities & Plans Integration of Orbital Data Sets: The LPRP Lunar Mapping and Modeling Project is tasked to ensure that LRO data sets will be geodetically controlled and co-registered based on a control network derived from the LRO/LOLA data. Exploration-relevant data will be geodetically controlled and co-registered. SMD will geodetically control and co-register science data. All LRO data will be available in the Planetary Data System LPRP has chartered the Lunar Geodesy and Cartography Working Group (modeled after the Mars Geodesy/Cartography Working Group) Chartered in late 2007 for coordination of lunar cartographic standards and constants Chaired by Brent Archinal (USGS) Membership from ESMD, SMD, external, international space agencies and lunar missions Will report results and findings to the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements 20

21 National Aeronautics and Space Administration Science Objectives

22 OSEWG Science Objective Team (SOT) Team: Interdisciplinary, NASA civil servant scientists Objectives: Conduct systematic science reviews of existing EARD and CARD Review output of other OSEWG working groups (Analogues and Surface Science Scenarios) to ensure consistency with EARD and CARD Begin generating and defining new science objectives not yet identified. Facilitate definition of science objectives in terms of threshold and objectives to facilitate architecture trade assessments Assess urgency of resolving uncertainty of science objectives based on when architecture development team needs the information. Propose recommended approach(es) to OSEWG leadership for prioritizing and further defining science objectives. 22

23 OSEWG Science Objective Team (SOT) Current Activity: Interdisciplinary science review of EARD and CARD for impact on science, identifying requirements as one of the following: requirement is conducive and adequate for science requirement could require additional study or trades for science requirement is inadequate or will prevent science OSEWG will use SOT results to: Submit request for assessment by Constellation Propose a change to current EARD and/or CARD Commission external studies or workshops to address yellow and red flagged issues (e.g. LEAG, MEPAG, CAPTEM, NRC, etc.) 23

32 Lunar Data Integration Activities & Plans General coordinates issues addressed: Have affirmed IAU Working Group on Cartographic Coordinates and Rotational Elements (and LRO Data Working Group) recommended use of the mean Earth/polar axis (ME) coordinate system for the Moon for creation of cartographic products Recommended use of the JPL DE 421 ephemeris to specify the initial lunar body-fixed frame in the principal axes system, with associated Euler angles, to define a ME frame Informal current gravity model recommendation of using LP155P, A. Konopliv et al. s update to their published LP150Q formal recommendation later after new models appear Working jointly with LRO Data Working Group to maintain Lunar Coordinates White Paper Have reviewed Constellation coordinate standards Planned: Developing recommendations or a standard for creating lunar mosaics and global map products Developing recommendations for assessing lunar digital elevation models Planning web site for distributing information and recommendations on lunar mapping standards and conventions Meeting COSPAR and NLSI conference Serving as forum for announcing new lunar data products (e.g. ephemeris, Lunar Orbiter mosaic) 32
