Optimizing Science and Exploration Working Group (OSEWG)

♦ Managing entity for collaboration and communication between and among ESMD, SMD, the science community, and associated partners, to achieve NASA's science and exploration goals

♦ Chartered in 2007 by ESMD & SMD [Direction: ESMD/DIO & SMD/PSD] to: •  Coordinate and guide science and exploration planning, including identifying and

providing science objectives and requirements for consideration of inclusion into the Constellation architecture

•  Generate and integrate science inputs to exploration program (current policy) –  Includes all science fields –  Includes all scenarios: including orbital, outpost, and sortie planning – Science objectives input provided by NAS, Decadal, NAC, NRC SCEM, LEAG

•  Focus ESMD-SMD coordination and communications – Science Objectives and Scenarios – Science Payloads (1 way and Roundtrip) – Analogs – Lunar Data Integration

♦  Engage science and exploration communities (LEAG, CAPTEM, MEPAG, industry, academia, NLSI, LPI, etc) for input, peer review and participation in planning, prioritizing and development of products

Develop Initial Integrated Campaign Manifest

•  Filter out all individual Science Investigations/degrees that cannot be satisfied due to a particular Resource constraint (e.g. # sites)

•  Accommodate remaining Science Investigations based on resource availability, accounting for Investigation Phasing

•  Balance tradable resources to support investigations

Assess Ability to Address Science Objectives

•  Table identifying degree and schedule associated with addressing each Science Investigation

•  Summary table of the # of Investigations addressed to varying degree

Continuing and Forward Work

♦ Continue & Evolve: Science objectives and requirements ♦ Continue: Assess science specific mass, volume, mobility, etc. ♦ Continue: Refine and refresh potential payload process & database ♦ Continue: Leverage various science interests via diverse support team and

external science ties to determine all lunar science functional needs ♦ Develop: Processes for traverse planning, sample & data acq,

documentation, laboratory analysis, sample return and curation ♦ Continue work with:

•  ILIADS for traverse planning •  LSOS for various information such as lighting along a specific traverse •  Analogs for development, testing and training •  LRO and other lunar orbiter programs to obtain data) for efficient science plans •  CAPTEM to determine science return and sample handling issues

♦ Continue: Identify technology needs and dev opportunities ♦ Maintain: Awareness of commercial & int’l activities/dynamics ♦ Proceed: Study scoping science & payload integration process ♦ Further Investigate: Outpost and Sortie variations over campaign evolution ♦  Identify: payload sequencing and research plans to establish refined

manifest and integration schedule 13

Design Reference Mission Structure of South Pole Aitken Basin (SPA):

Malapert Mountain

•  Field Trip to Malapert Mountain –  Duration: 3 days –  Distance from Shackleton Outpost: <150km radius –  Provisions

•  4 crew •  2 Small Pressurized Rovers •  2 science packages

•  Plan –  Day 1: Shackleton to edge of Malapert Mountain Rampart –  Day 2: Ascend and Descend Malapert Mountain Rampart; drive along rim through Malapert

chaotic debris field near base of plateau •  Stop 1 at edge of Malapert Crater debris field, gateway to upsloping outer ring rampart ‘plateau’ including

site survey, structural analysis, rock and subsurface sampling. Drive to Malapert Rim •  Stop 2 at Malapert Crater rim, rampart cliffs, work as Stop 1. Drive to highest point on plateau •  Stop 3 for survey and structural analysis, rock sampling, experiment package deployment. Drive to steep

edge of Malapert Crater rim •  Stop 4 on opposite side Malapert Crater, work as Stop 1. Drive to bottom of plateau and another crater rim •  Stop 5 at edge of that crater, work as before

–  Day 3: Edge of Malapert Mountain Rampart to Shackleton

Modeling What-If’s ILIADS Path Planning

Modeling What-If’s LSOS Simulation

•  Data gaps influence simulated path

•  Variation between “planned/desired” path & possible path

•  More like “Orienteering”
