Senior Space Systems Design Mars Scout Project Guidelines

Senior Space Systems DesignMars Scout Project
Guidelines

• Spring Semester 2005

2
Mars Scout 2011

• Competitive-award of robotic exploration mission
  established by Science Mission Directorate of the
  National Aeronautics and Space Administration.
• PI-led mission
• 2011 launch
• Less than 450M (FY07)
• Proposals for Mars Scout investigations that
  involve complete spaceflight missions including
  the experiment hardware, the spacecraft, launch
  services, mission operations, and science team
  data analysis (including archiving).
• Investigations proposed as Mars Scouts may
  include remote observations from Mars spacecraft
  missions that deploy aerial, landed, or
  penetration systems to study the Mars surface,
  interior, geopotential fields, deep subsurface,
  and/or sample return missions.
• Mars Scouts are intended to complement, extend or
  amplify and not duplicate core missions currently
  being planned as part of NASAs Mars Exploration
  Program or those planned by foreign space
  agencies.

MEPAG Scientific Goals and Priorities

• MEPAG has created a document outlining the
  science goals and priorities in each of four
  broad categories.
• Science goals and objectives are based on the
  current state of knowledge and the scientific
  questions that we are asking.
• The four broad categories are
• Past and present life,
• Atmosphere and climate,
• Geology and geophysics, and
• Human exploration.
• First report published in 2001 (R. Greeley et
  al.). Updated in response to new discoveries and
  recognized limitations in 2004 (G.J. Taylor et
  al.), and seen as a living document.
• Currently undergoing revision primarily in the
  area of Goal IV, dealing with measurements
  relevant to human precursor missions.

2007 Phoenix Scout Mission
10
2007 Competed Scout Mission Phoenix

• First in-situ investigation of existing surface
  and subsurface water, and assessment of
  habitability zones
• Odyssey data indicating ubiquitous water
• Mobility not required
• First of the Mars/Scouts competitively selected
  missions
• PI Peter Smith, University of Arizona
• Leverages existing MSP01 lander components, and
  MSP98 instrument designs
• Currently conducting thorough engineering
  heritage assessment of S/C prior to PDR /
  Confirmation Review

11
Team Assignments

• Teams have approximately 15 weeks to develop a
  pre-Phase A mission and system concept and the
  associated proposal.
• Teams responding to this AO are responsible for
  all aspects of a stand-alone space flight mission
  to be launched no later than December 31, 2011.
• Proposals for Mars Scout investigations will
  require careful tradeoffs between science yield,
  implementation risk, cost and schedule to produce
  investigations that return the highest possible
  science impact for the lowest possible cost.

• Launch no later than December 2011
• Total life cycle cost lt 450M(FY07)
• Investigations must be performed in the Mars
  system (no Earth-based observations)

  extend or potentially amplify science results of
  core Mars program

  instrument-only missions)

15
Project Deliverables

• Design concept review Oral presentation, Feb 23
• Draft Proposal Report (due Mar 30)
• Oral presentation ( Apr 6)
• Final Proposal Report (due Apr 20)
• Oral presentation (Apr 27)

16
Proposal Topics

• Science objectives
• What they are
• Why they are important
• Relation to core Mars program and MEPAG
• Measurement requirements
• Type, location and quantity of measurement
• Instrument selection
• Implementation options
• Major trades considered
• Design drivers and decision rationale
• Baseline mission
• Baseline architecture description
• Mission system
• Flight system
• Mass and power estimation, margins
• Design drivers
• Descope options including description of
  performance floor
• Project management approach
• Cost and schedule

17
First-Order Questions Proposals Must Address

• Do the proposed Mars Scout science objectives
  complement, extend, or amplify core Mars program
  results?
• Is the implementation approach traceable from the
  measurement requirements, and are these in turn
  traceable from the science objectives?
• Have the proper trades been performed to bound
  the design space in selection of an appropriate
  baseline?
• Has the team struck the proper balance between
  science objectives, engineering feasibility,
  mission robustness and life-cycle cost?
• Would you pay 450M for this science?

18
RASC-AL Competition

• 1-2 teams will be selected to represent GA Tech
  in the RASC-AL National Design Competition, May
  22-25 in Cocoa Beach, Florida.
• Travel support will be provide for all team
  members to attend this competition.
• Teams selected will be required to develop a
  report and oral presentation, according to the
  RASC-AL competition guidelines.
