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

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

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
