Mission

Mission• Launch

Vehicle: Delta II, Eastern RangeInjection: 305 km x 12 Re, 9.5 degrees inclinationDate: October 19, 2006

• Space SegmentSpacecraft: 5 Spinning probes with fuel for orbit/attitude adjustInstruments: 3-Axis Electric Field, Magnetic Field

3-D Ion & Electron Particle DetectorsOrbit Period(s): 1, 2 and 4 daysOrientation: Ecliptic normal (South Pointing Antenna)

• Ground SegmentObservatories: 20 Northern of All Sky Imaging and Magnetometers

• OperationsPhases: I&T, L&EO (3 mo), Campaigns (Dec-Mar),

DeorbitLifetime: 2 years


Programmatics

Programmatics• “PI/GSFC Team” Mode

PI Team Provides Space, Ground, Data SegmentsPI Team Provides Cost, Schedule, Performance AssurancePI Team Provides Education/Public OutreachGSFC to Provide Oversight in QA, Safety, LV, Range interface

• Cost and Schedule CapsSingle Cost Cap for the Mission Launch no later than March 2007

• Performance AssuranceMIDEX Quality Requirements

Implementation StrategyUse Heritage InstrumentationCoordinate Common Buy Parts Keep Probe/Probe Carrier Simple and Robust

Resources

FacilitiesChamber Availability at UCB/SSL

• Numerous Tanks of Varying Sizes & Types – All Still in Use by STEREO!• One New Chamber Needed for THEMIS – 3 Being Built/Tested!• One Calibration Chamber Needs Parts – Could not be Fixed, Replaced.

TV Plan Assumptions 2 Component-Level TV Cycles 6 Instrument Level TV Cycles

Schedule has assumed new chambers are ready.• Established weekly tag-up meetings on these TV chambers• Put people experienced in these systems on the project• Have contacted NTS (LA) for availability of chambers as a backup.


Cost

Changes from PDRAdditional Management• Added Swales/FSW Oversight

Growth in Probe/Probe Carrier• Added RCS Pressurant System to deal with Mass Growth• ESC Compliant Solar Arrays

Growth in I&T Costs• GSFC Review of P1 Qualification before P2-P5 Integration• GSFC Review of F1 Qualification before F2-F5 Qualification

Growth in LV Cost• All “TLX” separation system recommended by GSFC• Disallowed as a Mission Unique by KSC


Cost

Cost Performance v Budget thru MCDR• Cumulative Costs + Liens v Budget at +3%• Cumulative Costs v Budget alone at –19%• Schedule is appx –12% (bracketed by the float)

36 Decreasing POWER Margin on Probe

Power Cycle instruments. Degrades science.

Monitor Swales more closely. Implement low-power modes in IDPU & operational commanding to low-power during non-conjunction.

26 Probe may have a varying magnetic field in space.

A varying magnetic moment of the probe would degrade science

Implement rigorous Magnetic Control plan, implemented by UCLA. Add 100% test of all components to the plan.

2 5 10 WATCH

28 All 5 Flight and 1 Spare Instrument complement will be built before the first unit is integrated to Probe 1. The risk is that all units will have to be modified.

Cost to modify 6 units. Schedule to modify and retest 1 unit. This will delay the probe P1.

Implement ETU testing to demonstrate compatibility of instrument and spacecraft prior to multiple-flight instrument assembly.

3 3 9 WATCH

39 Flight BAU delivery late to Probe I&T and impacts Probe 1 Environments.

I&T would have to wait for the BAU Flight model before doing environmental testing.

Review schedule with GDDS. Make BAU engineering model a backup for I&T. Facilitate communication of design from Swales to GDDS.

40 LVPS schedule continues to slip as the Stereo project LVPS is slipping. The same personnel are involved in THEMIS.

IDPU & Instrument delay. Add personnel to LVPS team. 4 2 8 Mitigate

41 IDPU FSW schedule continues to slip.

IDPU & Instrument delay. Add personnel to FSW team. 4 2 8 Mitigate

42 ESA schedule continues to slip due to lead scientist holding layouts.

Instrument delay. Add personnel to ESA electronics fabrication team (H. Bersch). Deliver NASA comments to ESA lead scientist and to SSL Director.

Risk

Risk List (UCB, Top Down)# Risk Impact Mitigation P I RL Status25 Probe is magnetic. A large DC magnetic moment

of the probe would degrade science

Implement rigorous Magnetic Control plan, implemented by UCLA. Add 100% test of all components to the plan.

3 Frequency of the probes must be set now even without NTIA license in place (only Phase 1).

Transponder delivery will be delayed 1 year and 50% cost ($1M) if the frequency is changed after 12/03

GSFC Spectrum Manager should give as much confirmation as possible that we will have the frequency. If denied, Project must immediately notify bus manufacturer. Check monthly on status.

2 2 4 WATCH

21 Detectors may be radiation sensitive

SST Sensitivity would degrade until no signal at all

Add attenuator shield and close attenuator when in the solar wind flux is high. Implement radiation test of detectors.

Issues

Significant New Issues since PDR• Delay in Confirmation Review for 2 months

– No LV-to-Spacecraft Interface Definition for CDR

• Delay in Launch Date for 2 months– Decreased Time to Deploy 5 Probes Before 1st Winter– Will Switch Science Plans at some point if launch date slips more Need to have a clear launch-date decision point

• KSC Determination that TLX be Handled by UCB/Swales– Messy Organizational Interface with Boeing– If there is a mishap, this will be the “root cause.” Recommend a clear MOU on roles & responsibilities

• Delay in MMS and SNAP Projects– Difficulty in Offloading Personnel– Potential Cost and Schedule Impacts PM to develop offloading strategy
