NASA’s Goddard Space Flight Center 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.
