IMDC Study Goals

• Material which can be used as a basis for future
  study by the MAXIM team
• Each Discipline suggests future studies, building
  on this weeks work
• It may be only a small step from MAXIM Pathfinder
  for the full MAXIM
• Determine if it is reasonable to call this a 2015
  launch
• It is reasonable to do this, pending
  authorization and sufficient money
• Produce a life-cycle cost estimate
• Provided both as a grass-roots estimate and a
  parametric estimate
• Refine the mission profile (e.g., orbit analysis,
  etc.) as contained in the prework and opening
  presentation
• Concepts for Phase 1 and Phase 2 have been
  augmented and refined
• Terms Mode 1 and Mode 2 have been used in
  some places, but should be replaced with Phase
  1 and Phase 2 in future work
• Identify required technology miracles and
  performance drivers
• Miracles do not appear needed
• Technology developments needed for MAXIM are same
  as needed for several other future missions

3
These are Included in our Standard Work Package

• Nice-looking mechanical diagrams, graphs and nice
  sketches showing results of the study
• Included in the Mechanical presentation and
  supporting files
• Graphs and other sketches
• Included in many Discipline presentations
• Disciplines cover these topics
• MAXIM requirements that drive the subsystem being
  discussed
• Subsystem configuration
• Elements included (could be components, but great
  detail not expected)
• Mass and cost estimates
• Technologies required
• Identify tall poles, if any (technology needed,
  but not likely to be developed without funding or
  other emphasis from MAXIM)
• Identify items which are high cost in order to
  meet the requirements
• Tradeoffs performed or dead ends encountered
• Issues and items for future study
• Delivery CD-ROM will include all analyses done by
  the IMDC this week
• This presentation summarizes our work

MAXIM Information

• Following information in the LAI-MAXIM-PF Prework
  folder
• Prework, dated 10 April 2002 (Prework Report.htm)
• IMDC kickoff presentation on May 13, 2002 by
  Keith Gendreau (going-in-13may02.ppt)
• Information presented by Keith Gendreau to the
  IMDC and ISAL team in February 2002
  (PeriscopeDesignMAXIM.ppt)
• Other background information files
• Material from recent ISAL studies are also
  available
• Files are on idcsvr3 in a folder called missions.
  The ISAL studies that apply to LAI-MAXIM-PF are
  LAI Beam Combo (M) and LAI Super Star Tracker. I
  have mapped a network drive on my computer,
  calling it drive N, making it quick and easy to
  refer to these files
• Our August 1999 MAXIM study is in the misdir
  folder
• This is a moderately future, (15 yrs to launch)
  study of concepts and approaches design details
  are important, but will probably be changed
  before construction actually begins

Other Requested Trades or Studies

• TDRSS Support vs. direct to ground (for early
  orbit?)
• TDRSS often used for early orbit support of
  Launch and Early Orbit
• Use of a TDRSS-like relay from L2 vs. use of DSN
• TDRSS-like relay must be considered as a
  synergistic requirement by several L2 missions
• TDRSS development for use at L2 far exceeds DSN
  cost for MAXIM

6
Requested Standard Products

• Spreadsheets, bullet charts, or other briefly
  stated information useful to support ongoing
  analysis of this potential mission
• Information in the final presentation is a
  summary of work done by the discipline engineers
• System mass, power and cost spreadsheets, using
  real data where available and typical data for
  elements lacking specific information
• Actual values for mass, power and cost are used
  where known
• Educated estimates used where specific data does
  not extist
• Cost estimated using both grass-roots and
  parametric estimating methods
• Files of supporting analysis (e.g., Excel
  spreadsheets)
• Included on final CD-ROM
• Power System Sizing
• Included in Power presentation
• Mechanical sketches of the detector, hub and
  free-fliers in the launch shroud, in-transit to
  L2,deployed for Phases 1 and 2
• Included in the Mechanical presentation
• Additional graphic files included on the CD-ROM
