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.
