CSO Dome Removal Timelapse (2024)

The decommissioning of the Caltech Submillimeter Observatory (CSO) and the restoration of the site on Maunakea, Hawai'i was captured by a camera at Subaru Telescope, operated by the National Astronomical Observatory of Japan (NAOJ).
The telescope itself had previously been disassembled and brought down the mountain.

For context, they took this down so they could build another one on the same mountain.

Why tho? Concrete could be reused.

This makes me so sad.
