Death of Arecibo


Only 3 weeks after 1 of the mane 3" cables broke, the platform finally came down. It grazed the center of the dish & came to rest on the side. The gregorian dome, azimuth arm, & triangle are clearly visible. Barely visible in the lone low resolution photograph, the tops of the support towers also collapsed as expected. The backstay cables, relieved of tension, pulled the tops back. They were not looped over the towers like a bridge but fastened to the towers.

Lions were intrigued by how it could have been so marginally constructed, while suspension bridges have lasted forever. Obviously, there wasn't enough time for robots to do any good. Insiders saw that 1 strand was breaking every day in the last week.

Now, the process of recycling the metals can restore it to an empty field. The arecibo message transmitted in 1974 contained a graphic of the dish. The aliens who receive the message will come back to find only an empty field where it originated from.

So sad. I went and visited the telescope several years ago. It was an awesome feat of science and engineering.
