Fig. 1 - S2 (27.02.2020) - Lying in Puerto Rico, the Arecibo Telescope was a 305m radiotelescope built into a natural sinkhole.
Fig. 2 - S2 (08.12.2020) - Completed in November 1963, the Arecibo Telescope was the world's largest single-aperture telescope until 2016.
Fig. 3 - S1 (21.11.2020) - The Arecibo Telescope was primarily used for research in radio astronomy, atmospheric science & radar astronomy.
It was also used for the Search for ExtraTerrestrial Intelligence (SETI) program.
Fig. 4 - S1 (03.12.2020) - The telescope appeared in films such as for the climactic fight scene in the James Bond film GoldenEye (1995).
The telescope was damaged by Hurricane Maria in 2017 and was affected by earthquakes in 2019 and 2020. Two cable breaks, one in August 2020 and a second in November 2020, prompted to announce that the telescope would be decommissioned and dismantled.
Fig. 5 - S1 (23.11.2020) - Before it could be decommissioned, several of the remaining support cables suffered a critical failure.
Fig. 6 - S1 (05.12.2020) - The support structure, antenna, and dome assembly all fell into the dish on December 1, 2020.
