  1. 1. Follow Me to the Moon Cathy Peddie Deputy Project Manager Lunar Reconnaissance Orbiter (LRO)NASA’s Goddard Space Flight Center Project
  2. 2. NASA’s Vision For Space Exploration LRO’s Role Robotic Lunar Exploration Program Jan. 14 2004 – The President announced a new vision for space exploration that included among its goals “… to return to the moon by 2020, as the launching point for missions beyond. Beginning no later than 2008, we will send a series of robotic missions to the lunar surface to research and prepare for future human exploration.”NASA’s Goddard Space Flight Center
  3. 3. Lunar Reconnaissance Orbiter Mission Objectives Locate Potential Resources Safe Landing Sites Space EnvironmentHydrogen/water at the lunar poles High resolution imagery Energetic particles Continuous solar energy Global geodetic grid Neutrons Mineralogy TopographyNASA’s Goddard Space Flight Center Rock abundances
  4. 4. LRO Follows in the Footsteps of the Apollo Robotic Precursors• Apollo had three (Ranger, Lunar Orbiter and Surveyor) robotic exploration programs with 21 precursor missions from 1961-68 1. Lunar Orbiters provided medium & high resolution imagery (1-2m resolution) which was acquired to support selection of Apollo and Surveyor landing sites. 2. Surveyor Landers made environmental measurements including surface physical characteristics. 3. Ranger hard landers took the first close-up photos of the lunar surface• Exploration needs the above information to go to new sites and resource data to enable sustainable exploration. Lunar Orbiter ETU in Smithsonian Air & Space Museum, Washington DC NASA’s Goddard Space Flight Center
  5. 5. The Lunar Reconnaissance Orbiter (LRO) is NASA’s first step in returning humans to the moon. LRO focuses on the selection of safe landing sites, identification of lunar resources, and studies how the lunar radiation environment will affect humans. LRO will create the comprehensive atlas of the moon’s features and resources necessary to design and build the lunar outpost. The LRO mission will not only enable future exploration but also return lunar data that will significantly advance lunar and planetary science. The LRO payload, comprised of six instruments and one technology demonstration, will provide the most comprehensive data set ever returned from the moon..NASA’s Goddard Space Flight Center

  7. 7. LRO Mission Overview• Launch in early 2009 on a Atlas V into a direct insertion trajectory to the moon. Co-manifested with LCROSS lunar impacter mission.• On-board propulsion system used to capture at the moon, insert into and maintain 50 km mean altitude circular polar reconnaissance orbit.• 1 year mission with extended mission options.• Orbiter is a 3-axis stabilized, nadir pointed spacecraft designed to operate continuously during the primary mission.• Investigation data products delivered to Planetary Data Systems (PDS) within 6 months of primary mission completion.

  30. 30. Help!Traditionally in NASA projects, deputies are often added once “go ahead” has been given and/or the Project Manager “screams” for help!! NASA’s Goddard Space Flight Center
  31. 31. Deputy “how to” Guide• Establish expectations – What do you want from me? – What I want from you• Roles and responsibilities – How are we going to work together – Lines of authority – Good cop/Bad Cop – External (up & out)/internal (down & in)• Calibrate the situation – Styles – Skill mix – Strengths/weaknesses – Team environment• Work towards the “best” for both (and project) NASA’s Goddard Space Flight Center Slide - 31
  32. 32. Deputies wear many hats • Hot Back-up/Stand in • Technical Lead • Business Lead • Owner of Project processes • Complaints department • Coach • Trainer • Mentor • Counselor • Lead Pooper Scooper • “other duties as assigned”NASA’s Goddard Space Flight Center
  33. 33. Advantages to having a Deputy Sharing the work load Sharing the burden 2nd opinion, alternate viewpoint Sounding board Additional set of skills Complementary skills Validation of prime’s judgement “you are not alone”NASA’s Goddard Space Flight Center
  34. 34. Potential Pitfalls Confusion on who’s in charge Lines of Authority and Responsibility Must be clearly understood by all Must be worked out and orchestrated Must be supported Disconnected Leadership Vulcan mind meld or… Need effective communication & coordination Marginalization Underutilization of a key resource To truly have a back-up, shared knowledge base is key Too many cooks Roles & Responsibilities must be clearly definedNASA’s Goddard Space Flight Center
  35. 35. LRO’s PM and DPMo Project Manager & Deputy are truly partnerso Complementary skill set o Strengths & “non-strengths” are fully coveredo Relationship evolution o Adapted throughout project’s life cycles o Continuous “working it’o Flexibility, Process of Discoveryo Supportive of one anothero Loyaltyo Passion for the LRO Project NASA’s Goddard Space Flight Center
