MANUFACTURING THE PLATO OPTICAL BENCH: A LARGE, STABLE AND LIGHTWEIGHT STRUCTURE FOR 26 TELESCOPES

In 30 seconds

The PLATO optical bench assembly employs carbon fiber reinforced polymers (CFRP) to maintain the mechanical and thermal stability required for 26 high-precision payload telescopes. The structure functions as a backbone for the spacecraft, providing essential support for thermal and electrical hardware while minimizing interface tolerances. This manufacturing effort builds on established aerospace expertise to ensure long-term pointing accuracy for exoplanet transit observations.
