  9. I&T Verification Summary • Interfaces • Mechanical Integration; Electrical Integration Procedures; Polarity test; Alignment; Spin Balance; Mass Properties • Functionality Hardware • Functional Test; Performance; Time verification; End to End Tests; Deployment Tests • Functionality Software • Day in the Life; Separation timeline; Mission Sims • Environments • Contamination; Jitter Characterization; Sine Vibe; Acoustics; Shock / Separation Test; EMC;  Thermal Vac / Balance • Instrument Special Tests (unique configurations) • LOLA: Boresight alignment check; LAMP: End to End Test;

  10. Ground Support Equipment – Orbiter Level • Simulators: Instrument simulators, Spacecraft simulators; Flat Sat • Mechanical GSE • Lift fixtures, handling dolly, turnover fixture, transportation fixture, thermal vac support structure. • C&DH GSE • Front End Processors – S-band & Ka-band • 1553 Bus Monitor • Space Wire Test Rack • Data Storage • Workstations • RF racks & antenna hats • Time test rack • Power GSE • Solar Array Simulator; Battery Simulator; Load Box • ACS GSE • Dynamic Simulator; ACS component stimulators: Star Tracker, IRU • Propulsion module simulator/GSE • Instrument Unique Ground Support Equipment • CRaTER: CO60 source; non-ITOS workstation; Diviner: BCE; LAMP: Vac Ion, Pump, UV light source; LEND: Californium source; LOLA: Laser Test Equipment (BCE), target; LROC: none identified • Contamination • Instrument GN2 purges

  11. I&T Summary • Instrument requirements identified to date and understood. • Most difficult area will be thermal vac test configuration. • Testing may be limited by configuration limitations. • Other I&T requirements are not unique and can be realized. • I&T plan will be in released draft form by mission PDR. • Ready to proceed with preliminary design.
