SSL Contracting Status

• Phase B/C/D Contract in place.

3PFP MSR, 08/17/2010

Schedule Status

• Slack to CDR has eroded from 4.2 to 3 weeks, mostly due to delays in EM part procurement.

• Delay in PFP EM I&T results in delays in start of next FSW build, resulting in loss of slack in FSW delivery (11.4 to 7.8 weeks)– Puts FSW on critical path– Odd because FSW is actually ahead of schedule.

• Added 8w to schedule margin due to need date slipping to the right.

4PFP MSR, 08/17/2010

Manpower

• Ramping up complete– Added final ME to SWIA/STATIC team

• New position open to augment QA team due to Ron Jackson’s retirement

5PFP MSR, 08/17/2010

Accomplishments

• Completed all pre-PDR deliverables• Completed peer reviews, IPDR, MPDR• Most EM EEE parts on order – just a few actives and

some passives left– Part qualification testing has been delayed till next FY, which

adds some schedule risk in case parts fail screening

• PWBs are in layout• EM Mechanical parts are starting to go to fab• PFP FSW Boot code ~1/2 coded• Completed LPW sensor geometry trade

• More in instrument sections…

6PFP MSR, 08/17/2010

Ongoing Work

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

• Working parts issues with PCB• Completing layouts and mechanical part level designs• Working off RFAs

Trades

• Considering changing LPW boom whip caging– Nick Jedrich Mechanical Peer Review recommendation– Now that sensor geometry has been decided, can proceed.– 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

– Have ideas for mitigations which look promising– Plan for building a demonstration model to vibrate this month.

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

– SSL & LM current see no show-stoppers

9PFP MSR, 08/17/2010

Issues [1]

• Magnetics– Current sensor location on solar array probably does not work

• Too close to solar array strings• AC magnetics too high

– Working with Project on alternatives

10PFP MSR, 08/17/2010

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 progress

– 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

11PFP MSR, 08/17/2010

Issues [3]

• Amptek HV801 failures– Seems to be a lot workmanship issue– New lot in work at Amptek, but not certain they will be better– Projects ahead of MAVEN in trouble, will have higher priority for

parts• SWIA, STATIC use HV801• Alternative VMI part has acceptable performance

– Tested in breadboard– Much too large for existing layout– Significant changes would need to be made to accommodate

• mass, schedule impact

• Micropak has built equivalent demo parts with same form factor– Parts in test (one at SSL)

12PFP MSR, 08/17/2010

Issues [4]

• SWEA Planetary Protection– CESR part of SWEA FM build in progress– Will be assembled before the breakup/burnup analysis

complete• Current PP plan indicates SWEA is likely to burn up• SWEA is small, not a large contributor even if it does not burn up

– SWEA has stringent contamination concerns due to MCP, and so is already built in very clean conditions

– Need to decide if we need extra steps such as bio assay– This is the same as the rest of MAVEN, but with a sooner

trigger date• FM fab already started, mechanical assembly starts in November

13PFP MSR, 08/17/2010

Issues [5]

• Launch Loads– The current random vibe levels in the ERD are significantly higher than

anything we have worked to on previous missions• 23GRMS for forward deck mounted instruments• 47GRMS for MAG

– MAC curve limit loads are as high as 72g– Corresponds to design loads significantly greater than 100G, which is

the usual design target at SSL– Greater than qualification level for heritage instruments which were

expected to fly with minimal changes• SWEA, SEP, LPW booms

– A concern for some structures• Historically loads come down significantly once we get CLA

– CLA is due ~October, well before CDR• PFP plan is to follow LM’s lead and not redesign to these unrealistic

loads– When CLA comes in there is a risk we will have to do some redesign

14PFP MSR, 08/17/2010

Issues [6]

• THEMIS SST Attenuator anomaly– MAVEN SEP attenuator design is identical to THEMIS SST– THEMIS attenuator life tested to ~75,000 cycles– One of 10 flight attenuators failed to completely open after ~3

years on orbit and ~4,000 cycles• MAVEN expected life is ~2,000 cycles.

– Diagnostics indicate the problem is not the end-of-travel microswitch (an early candidate), but the “Nanomuscle” actuator itself

– Looking at ways to improve the actuator reliability– MAVEN has 2 independent SEP telescopes. Failure of one

attenuator impacts part of the science from one telescope; can still meet Level 1.

32PFP MSR, 08/17/2010

SWEA Status

• Mechanical– New mechanical parts fabrication and coating – ongoing (expect to

complete in September)

• Front-end Electronics (MCP, HVPS)

– Electronic parts procurement – done

– PCB fabrication – done

– HV optocouplers – procured, fabrication in progress, final assembly in September

– Transformers fab & test – fab complete, not yet tested

• LVPC & Digital– LVPC design/parts selection – done

– Digital design – schematic and final parts list done, checking PCB part information and footprint

33PFP MSR, 08/17/2010

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

and Ebanol-C.

– Samples procured and delivered to GSFC for testing.

– Laboratory tests are underway to measure electrical & thermal properties before and after exposure to atomic oxygen.

• Mechanical Design of Aperture– Current mechanical loads spec exceeds SWEA’s tolerance.

– Awaiting results of CLA analysis (expected October 2010).

– May need to redesign support ribs to make them stronger.

– Results in schedule delay, but still plenty of margin at CESR and SSL to handle delay.

STATIC Open Issues

• STATIC HV Sweep testing resumed – new HV opto-coupler testing started, still debugging HV oscillations.

• TDC needs layout changes to accommodate parts changes and remove ground bounce (add some capacitance) – negotiating for tech layout time

• STATIC FPGA still in development – need new test setup for complete throughput test (anode-preamp-TDC-Digital).

• Mechanical Attenuator still in development • Mechanical details of HV connectors still in development• MCP clamping spring force calculations in processes• New 15 kV / MCP board layout to proceed when EE is

available, VMI multipliers need to be ordered.• Waiting on order for carbon foils and carbon foil carrier frames • Waiting on feedback from campus with regard to refurbishing

the clean room (320D).

Action Items

PFISPDRRFA2 – Command and Telemetry Database

 

Action: When creating the Command and Telemetry Database for the PFIS follow mnemonic naming standards so that the database can be delivered to the Asist and OASIS teams.

 

Rationale: The developers of the FSW should be the originator of their respective database. Since the PFIS team is using their own flavor of GSE, they should create the database so that it is compatible with the project Command and Telemetry Database.

 

Originator: Tom Jackson/GSFC

Activity:Contact with LM regarding naming conventions have been through email. No document is readily apparent.Commands: 16 character limit, Upper Case Only, no special characters except “_”Telemetry: Upper and Lower Case UsedInstrument Prefixes:

SWE – SWEA instrumentSWI – SWIA InstrumentSTA – STATIC InstrumentSEP – SEP InstrumentLPW – LPW InstrumentEUV – EUV InstrumentMAG – Magnetometer instrumentPFP – PFP commands/telemetry not directly related to a single instrument.
