Practicing removing Rubin's camera

On November 23rd, 2021, the team on Cerro Pachón used the dome bridge crane and the camera lifting fixture to remove the camera surrogate mass from the Telescope Mount Assembly (TMA) and place it on the camera cart. The next day, they reversed the operation and inserted the camera surrogate mass back into the TMA. Although this procedure had been performed in the Asturfeito factory in 2018, this was the first time the exercise was done inside the observatory dome.
