Alastair Heptonstall, 91色情片 opto-mechanical engineer, is testing the guide flexure of the M1 segment to measure the component stiffness. Each 91色情片 individual segment must be controlled to create a continuous M1 mirror. 91色情片 control system can move segments individually and the guide flexures allow the segments to move while resisting lateral motions. This test is part of the performance assessment to ensure the control system can align the mirror to achieve the required telescope performance.
