  • 1. Planck Reflector Programme Principal Investigator: H.U. Nørgaard – Nielsen Danish National Space Institute (DTU Space) Reflectors build by ASTRIUM, Friedrichhafen under DTU Space and ESA contract
  • 2. PLANCK Reflector Programme Planck reflectors: 2 ellipsoids Design drivers: Mass, stiffness, thermal stability (RT -> -220 C)
  • 3. Field of View: ± 4 deg PLANCK Reflector Programme
  • 4. Planck Carbon Fiber Reinforced Plastic Facesheet Honeycomb structure PLANCK Reflector Programme
  • 5. Extensive FEM calculations Interferometer measurements at Centre Spatial de Liege Secondary reflector Cool down: RT -> -220 ° C PLANCK Reflector Programme
  • 6. On ground tests and simulations of the optical performance will be checked through observations in orbit of Planets (e.g. Jupiter Mars) Planck telescope PLANCK Reflector Programme
