SSL Contracting Status

• Phase B/C/D Contract in place.

3PFP QSR, 10/19/2010

Schedule Status

• No improvement in pre-CDR schedule – Power Converter Layouts started, but still lagging– SWIA/STATIC mechanical still behind but making progress– Due to personnel conflicts with RBSP

• FM1 through environments, FM2 in environmental tests, so end in in sight

• See next chart

• Also the ICDR date has been set, ~3 weeks earlier than previously planned

• Result is the EM system testing completes right about the time of the ICDR.

• No impact to CDR to Delivery margin (19w margin)– Flight build is currently gated by completion of MCDR– Delivery to ATLO moved up 1 week in latest REC-DEL list– MAG currently on critical path

4PFP QSR, 10/19/2010

Manpower

• Concern with competition with RBSP-EFW for some key people– Power converter design team

• Reorganized team to streamline priority tasks– SWIA/STATIC/LPW boom mechanical engineers

• SWIA/STATIC EM mechanical parts behind• not yet on critical path to EM I&T

– FSW lead• keeping ahead of MAVEN schedule

– Additional parts engineer to be added to QA team• New hire: Job listed, advertized, should be filled soon.

5PFP QSR, 10/19/2010

Accomplishments

• LPW ‘hingelss whip’ test model built, vibration tested– Passed using latest Atlas 5 loads and new aft deck levels

• 11.9grms random, 1 min.wmv

– Also ran case with additional margin and also a sine vibe, all OK– can eliminate caging system

• All EM and some FM EEE active parts on order, 87% delivered to GSFC– Remaining parts delivery dates meet schedule– Part qualification testing has just started, which adds some schedule

risk in case parts fail screening• PWBs are in layout• Most EM Mechanical parts are in fab

– Some part-level design work still in progress on SWIA/STATIC• PFP FSW Boot code 93% coded; operational code started

• More in instrument sections…

6PFP QSR, 10/19/2010

Ongoing Work

• Supporting Project planning process• Supporting EMC, Payload, SDT working groups

• Getting the last of the EM parts on order (passives)• Working parts issues with the PCB, getting qualification

tests started.• Completing EM layouts and getting EM mechanical parts

ordered• Preparing for STATIC TOF system acoustic test next

month

7PFP QSR, 10/19/2010

EM Status Summary

• SSL EM & GSE Layouts (23)– 11 complete– 9 in progress– 3 awaiting final schematic release

• LM Interface Test preparations (3/25/2011):– DCB board layout complete, PWB in fab, parts being kitted at GSFC– GSE & FSW ready to start testing– Current schedule shows ready by 1/5/2011 for the LM test

• EM EEE Parts– All active parts ordered, 87 of 94 types delivered to GSFC– Connectors on order– Passives being ordered

9PFP QSR, 10/19/2010

Trades

• Considering changing LPW boom whip caging– Nick Jedrich Mechanical Peer Review recommendation– Change from caged to fixed whip

• Deletes caging mechanism mass & resources• Deletes whip hinge• Deletes an actuation• Simplifies qualification

– Concerns being investigated• Enhanced vibration on whip, preamp

– Built a demonstration model and completed vibration test to predicted levels plus margin, no problems.

• Potential damage to exposed whips during I&T– Possibly remove whip for some of ATLO

– PFP team believes we should go with the fixed whip• Need to submit a CCR & ECR for this change• Whip fundamental is below 100Hz (~25Hz). LM tells us they don’t

need a Structural Math Model (CDRL SE-05).

10PFP QSR, 10/19/2010

Issues [1]

• Magnetics– New solar array configuration selected

• U-strings, small increase in ‘diving board’ length– Analysis indicates new configuration meets requirements for

most conditions• Assumes outer-most strings don’t switch• Will see a transient going in and out of shadow• Acceptable

– MAG Team and EMEWG will continue to watch magentics

11PFP QSR, 10/19/2010

Issues [2]

• SWEA Surface Treatment– Need to modify thermal characteristics of surfaces in SWEA

aperture to avoid excessive heating - candidate solutions in work– Candidate solutions need to be evaluated for Atomic Oxygen

effects, charging effects, thermal properties, and robustness• AO test in complete, waiting on test report, post-test surface

resistivity measurements– Current candidates: DAG213, Ebanol-C, Black Nickel, Black

Chrome, Z307– SWIA and STATIC also interested

• SEP detector Atomic Oxygen effects– Heritage instruments survives AO, but we would like to test a

MAVEN detector if possible.• Included in the test

12PFP QSR, 10/19/2010

Issues [3]

• Amptek HV801 failures– Solved immediate problem for EM – NGIMS providing parts

• Still pursuing three options for flight– New lot of Amptek parts

• In queue behind MMS– Micropak parts

• Some concern at GSFC about internal spacing of HV parts• May be OK for us as we do not exceed 5kV

– VMI parts• Larger, would require repackaging of SWIA, STATIC

13PFP QSR, 10/19/2010

Issues [4]

• SWEA Planetary Protection– CESR part of SWEA FM build in progress– A memo has been developed by Project defining Planetary

Protection implementation at CESR which CESR has agreed to.– Issue Closed.

14PFP QSR, 10/19/2010

Issues [5]

• Launch Loads– Selection of Atlas 5– Launch loads have been reduced significantly– ERD update pending based on acoustics

• SWEA heritage design may be OK with new loads– Depends on how you interpret factors of safety– Discussions ongoing with LM & GSFC

• Remaining instruments are OK with new loads

• Liens:– Expect to need operational heat during eclipse

• None allocated for most instruments; amount needed pending thermal analysis

• Preliminary estimates included for MAG and EUV• IPDR numbers for the remaining instruments are up to 13.3W (worst case

cold)– Does not look like LM-provided sinks change this much– Can decrease operational power requirement by ~3W by coupling SWEA to its

ballast mass

28PFP QSR, 10/19/2010

SWIA Progress

• Layout Progress– Anode board layout complete, out for quote for fabrication– Preamp/MCP board layout in progress, now top priority– Digital board placed but not routed, likely headed to subcontractor– LVPS layout done, out for quote soon– SWP in progress, settled on shared layout for SWIA/STATIC

• Mechanical Design Progress– First priority: Support layout

• Most mechanical design now done for boards– Settled connector issues on boards shared with STATIC– Some work to be done on HV connectors, but settled on scheme

– Second priority: Flesh out attenuator and Anode/MCP housing• Anode/MCP housing and clamp stack design complete

– Mechanical drawings complete and in review, out for fab soon• Attenuator design next to receive major effort

– Third priority: Detail analyzer design• Settled issues in interface region between analyzer and electronics

box by splitting SWIA/STATIC analyzer designs slightly

• Microchannel plates arrived, testing starting soon

29PFP QSR, 10/19/2010

SWIA Issues

• Staffing– ME staffing continues to be an issue

• Dalton and Johnson splitting time with RBSP• Situation should ease greatly in ~November

– Layout queue is still tight

• Layout Complications– First anode layout had some potential issues

• Revised layout now complete, but queue set back somewhat– Sweep board required coordination between SWIA and STATIC

• Settled on scheme that works for both (with slightly different schemes for HV connection to inner hemisphere)

• Next hurdle: Working on selecting chamber for MCP testing

33PFP QSR, 10/19/2010

SWEA Status - SSL

• Pedestal Mechanical– Purge redesigned to point in the right direction

• change to CESR mechanical design is very minor

– Wall thickness increased to 0.100” for better margin in Mars radiation environment.

– Drawings complete, fab out for quote. If all goes well, expect delivery in November.

– Design of solar absorber awaiting thermal analysis, but this will not hold up the EM design/fab.

• LVPC– Layout based on STEREO SWEA, with modifications because MAVEN

SWEA does not have a STE component.

– Parts selection done, layout in progress.

• Digital– Design complete, layout engineer selected, PO in process.

34PFP QSR, 10/19/2010

• Surface Coating for Deflectors and Toroidal Grids– Candidates are: black chrome, black nickel, DAG213, Z307, and

Ebanol-C.

– Laboratory tests at Glen were recently completed to measure electrical properties before and after exposure to atomic oxygen. Expect report within a few days.

– FM parts coating can proceed once material is selected.

• Mechanical Design of Aperture– Estimates of launch loads have come down significantly with selection

of Atlas V and addition of ballast mass to the SWEA boom.

– Previous load tests on STEREO SWEA show that current design may be adequate for MAVEN. Currently working to confirm.

• FM Front-End Electronics– CESR procedures, with minor modifications, are compatible with

MAVEN Planetary Protection Plan. FM board assembly can proceed.
