## Micro Arcsecond X-ray Imaging Mission, Pathfinder (MAXIM-PF)

**May 13-17, 2002**

**Opening Comments**

**Micro Arcsecond X-ray Imaging Mission, Pathfinder (MAXIM-PF)**

## 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
