Post PDR characterization testing

F-DFB01PM


If the Sidecar experiences latent failure and/or has reliability issues, then the lack of a complete EIDP and respective workmanship could hinder the debug/troubleshooting, and have the potential to degrade performance and warrant possible redesign which could increase needed mass and power. Risk mitigation plan is to perform characterization and environmental testing on Sidecars. These parts have prior electrical burn-in testing hence characterization and environmental tests will demonstrate good rigor to retire the risk.

Risk rating: Probability 2, Impact 3; not likely to occur based on successful burn-in testing completed by vendor [GSFC/Teledyne]; consequences slightly higher based on possibility of reverting to backup plan of discrete ADCs. Proposed/heritage ADCs are not as rad-tolerant, require more board space (mass increases), more power, and/or could drive science return. Newer, more viable, ADCs identified but require radiation testing.

SPP MAG Status

• Some scheduled MAG activities have slipped; however, we are now in receipt of most information (ICDs, etc.) and materials needed, and we have a clear understanding of the path to PDR.

• The AC Heater (ACHE) PCBs have been laid out and procured. They will arrive next week and will be populated and tested ASAP.

• Macor bobbins and other procurements are nearing completion, facilitating the build up of the ETUs.

• Significant progress with thermal modeling for the MAG sensors has allowed a better understanding of constraints and mitigations of the thermal range; we are interested in results from Gail Martin on any additional power available.

• Thermal testing (-50 to +50 C) of GSE sensor (Macor base) is currently being conducted in a non-windowed thermal vacuum chamber (see photo on next slide). First goal is to determine how fast we can cycle.

• Design of a composite base for the ETU MAG sensors is completed.

• Ongoing concerns include: MAG sensor placement on boom relative to spacecraft, power, etc., available to increase low end MAG sensor temperature, alignment error budget numbers, boom harness plan, conclusion of L4 requirements & ICDs

MAG thermal vacuum chamber #1

• Chamber shown at right permits operating over a large temperature range (order of -100 to +100 C) at < 10^-5 torr. (Same aluminum cylinder is also the “insert” for the windowed TV chambers.)

• Currently instrumented (8 thermistors) and being used to determine the rate at which we can cycle the MAG “GSE” sensor temperature, which has consequences for all future thermal testing.

• Since chamber has no windows, the sensor alignment inside chamber cannot be determined, i.e., no calibration over temperature.

• We can calibrate zero levels, etc., before and after thermal cycling. If they do not change, then we can conclude that calibration as a function of temperature will be possible – adequate for PDR. TVC #1 working in GSFC Mag Lab.

Risk Notes: April 2013

F5 – Survival Thermal Environment (chart 7)- new data elevates risk over concern regarding the MAG thermal model

(probability increase to 3). May need more heater power then what is allocated- believe an updated thermal model is needed to proceed in lowering this risk

F15 – SCM Funding (chart 17)- FIELDS had a discussion with the Backup SCM lead at GSFC; it was determined that the heritage SCM is larger and heavier than the French device.- Thus, substantial redesign work will be required to accommodate the GSFC unit.- On the plus side, though, GSFC is available to support SPP on this effort, with a baseline schedule beginning in June 2013 (if needed)- believe an updated thermal model is needed to proceed in lowering this risk

Risk Notes: February 2013

1) F10 – Antenna Qualification (chart 12): Risk burn-down updated to reflect the current state of Antenna Qualification testing:

• APL is completing materials testing on the coupons that underwent high-temp testing at Glenn Research to determine if the material properties were affected by the high temperatures.

• The antenna qualification thermal testing (currently scheduled for March 2013) may be moved to September 2014. This would still permit testing to be completed prior to FIELDS I-PDR.

2) F13 – Third Axis Electric Field (chart 15): Lowered likelihood to “1” based on the completion of determining that it’s possible to do the measurement. Added the final step of confirming the addition of this to the complement of measurements in the draft ICD in May 2013.

Risk Notes: January 2013

1) F15 – SCM Funding Issues (chart 17): Decrease the likelihood from 4 to 3 per discussions at NASA headquarters, in international affairs, are proceeding with CNES. Detailed discussions have commenced.

Risk Notes: December 2012

1) F3 - Foreign Funding (commitment) (chart 7): - Risk retired and replaced with a more relevant, SCM-specific risk; New risk F15 – SCM Funding Issues

2) F15 – SCM Funding Issues (chart 17): If foreign funding sources failthen we may lose the French search coil sensor and would switch to the backup - created to capture the SCM-specific funding issues - expect CNES to re-evaluate SCM funding by Jan or Feb ‘13 - if CNES does not sign the LOA explore:

- alternate HW source (3D Plus) for LPCE; or- funding the backup option at Goddard

3) F16 – MEP Thermal Environment (chart 18): If the MEP high temperature AFT remains over 55 deg C; Then FIELDS heritage electronics may need to be re-designed to accommodate the higher flight temperature. - MEP panel temperature is expected to be 55 deg C so, the allowable flight temperature may be 65 deg C which may lead to some parts issues. Change approach to mitigation if it's determined that parts need to be changed. - Determine if the MAVEN thermal design is adequate for FIELDS (end of 1/13)- Confirm all parts meet the MEP high temp AFT (by iPDR)
