The Planck telescope will be tested soon at low temperature (100-110K) in the Large Space Simulator test facility at ESTEC.  The objective of this test is to measure the deformations of the fully integrated Planck FM telescope at low temperatures with video-grammetry.

The Planck telescope is the black coloured frame with two upper struts supporting a panel (the Primary Reflector Panel).  The reflectors are not yet integrated.

The telescope frame is supported by struts (the Cryo-Structure struts).  At the bottom of these struts, a horizontal panel is added for thermally decoupling the conical structure (silver coloured) from the rest of the structure.  The cone will be at room temperature during the test.
