The model is undergoing preparation for a major test that will be performed in the coming weeks: videogrammetry measurements of its geometry, at room temperature and also under vacuum at low temperature (around 100 K, or -173 °C), in ESTEC's Large Space Simulator (LSS) facility. Preliminary videogrammetry measurements have already been taken today 27 June, while the telescope is still outside the LSS vacuum chamber and such measurements are still relatively simple to perform.

After a full Test Readiness Review to be held in the first days of July and a pump-down and cool-down period, the videogrammetry measurements of the telescope at low temperatures (100-110K) will be performed in the Large Space Simulator.
