1. Final Version John Martin May 13-17, 2002 Opening Comments Micro Arcsecond X-ray Imaging Mission, Pathfinder (MAXIM-PF)

2. Final Version MAXIM-PF, May 13-17, 2002 Goddard Space Flight Center Opening Comments Page 2 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 week’s 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. Final Version MAXIM-PF, May 13-17, 2002 Goddard Space Flight Center Opening Comments Page 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

4. Final Version MAXIM-PF, May 13-17, 2002 Goddard Space Flight Center Opening Comments Page 4 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

5. Final Version MAXIM-PF, May 13-17, 2002 Goddard Space Flight Center Opening Comments Page 5 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. Final Version MAXIM-PF, May 13-17, 2002 Goddard Space Flight Center Opening Comments Page 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
