Today in the Planetary Science Journal:
Stickle et al. 2024, "Tour of Asteroids for Characterization Observations (TACO): A Planetary Defense Asteroid Tour Concept" - https://iopscience.iop.org/article/10.3847/PSJ/ad7a6c
@schmemela , @asrivkin , and company present a new concept for a flyby mission that visits numerous near Earth asteroids.
Including #1998OR2 , which was one of the last asteroids imaged by #TeamRadar with the #AreciboObservatory in 2020.

This failure analysis of the #AreciboObservatory collapse is fascinating. https://nap.nationalacademies.org/catalog/26982/failure-analysis-of-the-arecibo-observatory-305-meter-telescope-collapse
One of the conclusions is that the never-seen-in-100-years failure of the zinc cable anchor plugs may have been caused by fatigue due to induced currents from the radio transmitters used for the dish...!

The National Academies report outlines a potential cause for the additional creep of the zinc at the #AreciboObservatory :
Induction during #TeamRadar transmissions producing current in the cables; which was conducted through the anchors and the towers to the ground, heating up the zinc just slightly in the process.
By itself, this would have been manageable. In combination with the damage from Hurricane Maria and other effects, it was eventually not.

The 47-year-old mystery of the "Wow! Signal" might finally be solved! Scientists from the Arecibo Observatory suggest it was caused by a rare astrophysical event, such as the brightening of a cold hydrogen cloud due to a magnetar flare. This groundbreaking discovery redefines our understanding of such signals and could guide future searches for extraterrestrial life.

“After weathering hurricanes, earthquakes, budget cuts and a pandemic-induced shutdown, the iconic #AreciboObservatory in #PuertoRico closed its doors on 14 August. After its main instrument collapsed two years ago, the site was supposed to shift from carrying out astronomy and other research to being a science education centre. But concrete plans for that have yet to materialize — and funding for current operations has run out.” -

The last #RadioTelescope at #AreciboObservatory has been shut down.
"...after 14 August, only 18 staff members will remain to maintain the site until the new management comes in." That is, if they can find funding.

"AO Computer Accounts Final Closeout August 14, 2023"
I wish it had not come to this.
And thanks go to Arun Venkataraman for managing the #AreciboObservatory computer system; without which nobody would have been able to use the telescope.
