7.5.6 Secondary Mirror Tower Partial Structure Testbed<br />
Scope<br />
The current plan is to have this testbed competed, designed and built through Phase A, with<br />
model validation and other technology objectives completed in the early-to-mid-Phase B time<br />
frame. The secondary mirror tower partial structure testbed has achieved TRL 3. The testbed<br />
schedule is given in Table 7-16.<br />
