Title: Mars Exploration Program

Mars Exploration Program
MEPAG February 20, 2008
Those who labor over robotic missions are some
of the great explorers of our times, even though
their feet never tread the soil of another
world National Academy of Science Assessment
of NASAs Mars Architecture 2007-2016

AGENDA
  • Key Accomplishments and Program Status
  • Mars Sample Return Progress
  • Mars Program RADr. Jim Green

3
Key Accomplishments
  • Scout--2011
  • Phase As completed and Concept Study Reports
    received
  • During review, a conflict of interest was
    identified that resulted in a slip to 2013
  • Selection planned September 2008
  • ExoMars--2013
  • ESA Implementation Review Board in May approved
    baseline mission
  • No orbiter but full 16.5kg payload2 US
    instruments included
  • NASA provision of telecommunications, engineering
    (w/in ITAR constraints) and science adopted
  • Requested NASA provide landing site imagery and
    dust storm monitoring for landing
  • PDRs start in early to mid 2008
  • Urey and MOMA selected for technology development
    as MoOs under Scout AO
  • Tech development selections due to immaturity and
    2-year ExoMars launch slip
  • Independent Assessment Panel chartered by HQ to
    work with UREY and MOMA
  • Focus is Technology Readiness Levels, budgets,
    etc.
  • Selection process and additional technology
    development in planning
  • Mars Sample Return2018
  • US Studies underway for FY10 POP process

4
Key Accomplishments
  • National Academies Solar System Assessment
    ReportMars
  • Released in December 2007 Mars Program assessed
    against
  • 2003 New Frontiers in the Solar System (Decadal
    Survey)
  • 2003 Assessment of Mars Science and Mission
    Priorities
  • 2006 Assessment of Mars Architecture
  • Key recommendations
  • Active planning for MSR? In progress

5
Mars Sample Return
6
Mars Sample Return Progress
  • Mars Sample Return is the Programs major focus
    for the next decade
  • Objectives
  • Develop affordable and successful first sample
    return mission
  • Ensure science value is worth the investment
  • Include international collaboration to enhance
    science, mitigate risk, and share costs
  • New planning for MSR started Fall 07
  • Mars Exploration Program planning
  • Advisory groups
  • International cooperation
  • Significant efforts are underway to plan
  • US-only mission capped at 3.5B
  • Internationally-dependent Mars sample return
    missions
  • IMARS international working group chartered by
    IMEWG
  • NASA-ESA bi-lateral activities

7
MSRs Expanding International Nature
  • International interest in 2020 mission expanding
  • NASA dates align with ESA Aurora Program MSR
    plans.
  • ESA considering adding caching to 2013 ExoMars
    mission.
  • NASA offered the MSL cache ExoMars real estate
    limitations
  • ESA proposed a 2016 Mars MSR precursor mission to
    Programme board in Feb 08
  • Initial funding request to November 2008
    Ministerial
  • ESAs Aurora Program contains MSR in 2020
  • Largely aligns with NASA/MEP timing
  • NASA Leadership planned, with ESA partnership
    (30-40)
  • IMARS provides opportunity for individual
    countries to participate in shaping an
    architecture and joining the partnership
  • The potentially paradigm-changing nature of
    sample return from Mars, and mission expense,
    lends itself to an international effort
  • IMEWG-chartered working group (iMARS) is critical
    to solidifying plans, architectures, partnerships

8
Supporting Efforts for MSR Concepts
  • MEP planning
  • Established Program Executive and JPL/MPO Team
  • Overall planning, technology, architecture,
    planetary protection, etc.
  • Dual-function as US support to IMARS team formed
    by IMEWG
  • Critical milestone for MSL implement-ability
    through FY2010 budget process
  • ND-SAG
  • Analyze critical Mars science that can be
    accomplished in conjunction with MSR
  • Evaluate science priorities guiding the makeup of
    the sample collection to be returned by MSR
  • Determine dependencies of mobility and surface
    lifetime on science objectives, sample
    acquisition capability, diagnostic instrument
    complement, and number and type of samples.
  • Support MSR science planning as requested by
    IMARS (international participation)
  • Technology Workshop February 6-8
  • High-level survey to assess current state of the
    art in key MSR technology areas
  • Validate assumptions on
  • Availability
  • Technology Readiness levels
  • Key Technology Challenges
  • Identify new technologies or developments

9
Draft Baseline Architecture
  • Baseline two launches
  • Orbiter w/EEV
  • Lander w/rover and MAV
  • One landing site w/one lander
  • If cost vs. risk reduction indicates multiple
    landers/rovers, additional science objectives can
    also be met
  • Same major building blocks, shared testing, same
    workforce, common parts to minimize cost, etc
  • Latitude /- 30 degrees, Landing elevation lt
    0km MOLA
  • Time on surface driven by number of samples and
    sample suites
  • Design for 12 months
  • Horizontal mobility is necessary
  • Have to return to lander from sample siteround
    trip travel!
  • Samples packaged separately in airtight
    containers
  • Thermal control lt 20C
  • Additional Features in IMARS Intl MSR
    Architecture
  • Precision landing is a requirement
  • Land within 100m - 3km of highest priority sample
    site
  • Trade between precision and landed mass
  • Special region would not impose requirements
    beyond those required to avoid organic
    contamination
  • Study feasibility and cost/mass of -10C thermal
    control
