A lot of people apparently had an emotional connection to this satellite, I guess because it was in popular media. Such people are now overplaying the importance of this instrument. Many are even speaking of it with quasi-religious language, like pic related on slashdot calling it an "Icon."
>An icon or ikon (from the Greek εἰκών eikṓn 'image, resemblance') is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, the Roman Catholic, and certain Eastern Catholic churches. They are not simply artworks; "an icon is a sacred image used in religious devotion".[1]

Basically, the "I FUCKING LOVE SCIENCE" crowd are in tears. They don't know why this instrument was important but they're sure it must have been because it was famous, and really that's what's important to them.

Arecibo was created to track missiles. It was reappropriated to studying astronomy. There is a 0% chance it will ever be replaced which is sad, as old as it was it was the only radio telescope able to send out radio waves in order to map near earth objects. It will be missed.

Big dishes are so old century. I thought arrays are the future. You can set up bunch antennas around the world and coordinate them with computers over a network. It can filter out local interference, point in any direction, emit signals too I guess.
Earth sized AESA radar when? We could even make it coded frequency hopping, low probability of intercept thing like in F-22 so the ayy lmaos won't tell it apart from background noise unless they're too close.

aricebo is only popular with sci-fi faggots, plebs and other know-nothings because it was part of SETI and the SETI program itself was only ever taken on to appease sci-fi faggots, plebs and other know-nothings. aricebo was more of a hollywood prop and less of a telescope, it was about as useful as the spruce goose

Without a suitably large dish the noise in the receive electronics is rather big compared to the received signal. The gain of a large dish is not to be sneered at.

[Anonymous No.12412100]

>>12411975
>1. world sized phased array of omnidirectional antennas
The wider the beam the more power you need to get the same signal. Assuming this array was only as sensitive as Arecibo is now (but in every direction), it would take 30 million times more energy. You're talking 30 petawatts. It isn't feasible in the current time.

Note also that Arecibo is still shit for finding asteroids, it can only study ones which happen to be very nearby. Not only would it cost an absurd amount of money but it would be bad at finding asteroids, optical/infrared telescopes are far more efficient at the task.

> We could even make it coded frequency hopping, low probability of intercept thing like in F-22 so the ayy lmaos won't tell it apart from background noise unless they're too close.
No you can't. by the time you've changed frequency the random noise is different. Changing frequency doesn't let you magically detect signals that are buried in the noise. You need long integrations.

[Anonymous No.12412122]

>non steerable telescopes are worthless
Arecibo can point, it's not a zenith telescope. It can point about 20 degrees away from zenith.

>if they were worth anything then you people would've hear of the spinning mercury pool optical telescope in canada and astronomers would be fighting over who gets to use it next and they'd be demanding money to build bigger ones.
That's some fucking shitty logic right there. The large zenith telescope was shit because it was a) smaller than conventional telescopes that already exists b) didn't have any decent instruments. A telescope is only as good as it's instruments. Neither of these apply to Arecibo.

>aricebo is only popular with sci-fi faggots
You have no idea what you're talking about. Hulse and Taylor won a fucking Nobel prize from Arecibo data. It was used to discover the first exoplanet. It's productivity has certainly declined but you know nothing if the only thing you can think of is SETI.

The cables were pulled and slacked to move the dome, giving a 20 degrees change in beam position. Thus all three cables could have been slacked.

>>12416856
>I still can't see adding slack being any good
It would have reduced the tension in the cables and in the anchoring. Cables were frayed and the anchor ripped but I cannot tell the order of events that lead to the disaster.

Nope. The feeds were moved on the track of the azimuth arm, which itself rotated. The cables and upper platform don't move.

So how well does the Chinese dish work with such a tiny platform compared to that? Inside that dome there were so many different antennas they were on a platform to rotate into place.
