    Holy crap that thing was ginormous.

    Kind of had to be. Though these days most radio observatories being built just use an array of smaller dishes spread way out. But Arecibo was just this massive thing... it's a real shame to see it go just on account of it looking pretty cool on account of being this massive empty bowl in the woods.

    A dish array has better resolution (sees finer details) than a large single dish. However, a large single dish has better sensitivity (sees fainter signals) than an array of smaller dishes.

    Just remember that half the people you meet are below average intelligence.

    It's clear then.

    We need an array of giant dishes.

    This made me realize you could do a Lagrange point one, and apparently a budget proposal for it was written a decade ago. Just needs a bit over a billion in funding. With approx 2.5m km between them, that's a pretty decent sensitivity.

    Sol-Earth. I considered Sol-Jupiter but the transmission times get silly. Plus it’s not like we need to be able to detect flare activity on Proxima Centauri, right?

    L3 is an interesting choice. You can't put something directly at L3, as it is unstable, so you'd either waste a lot of fuel, or need to be in a slightly erratic orbit, which would need to be compensated for (more so than L4/L5).
    Then, you also wouldn't be able to directly get the feed from L3; the Sun's in the way, so you'd have to feed it via a relay. This is easily resolved - after all, you have L4/L5 as part of the system anyway, but now you have to add additional transmission camabilities to the stations. I mean, they're already the biggest most sensitive radio listening dishes in the solar system, so I'm sure we could handle this, but I do worry about cross-contamination of signal. Some dishes on earth have been shown to be sensitive to the microwave being used in the kitchen, and now we want to be targeting them with a secondary signal containing the raw data feed of one something also as sensitive as itself?
    It's not to say these problems are insurmountable, just that L3 is complicated, and might require solution engineering such that it might actually be easier and cheaper to just go with the Jupiter lagrange points anyway.

    Or... just use L2 or something? That avoids the issues of communication easily and I think actually creates a slightly bigger triangle anyways. Still has stability issues, but.

    Oh that's cheap.

    What kind of materials can you use for these in space? I assume inflatable dishes are out of the question?

    Climate change, capitalism and disease are threatening to strike a mortal blow to the world's rubber trees. Do we need to find alternative sources of rubber before it's too late?

    But how has such an important commodity fallen into such peril in the first place?

    The global supply of natural rubber – around 20 million tonnes per year – is produced almost entirely by fragmented smallholders working tiny plots of land in tropical forests. Millions of these workers tend to plantations in Thailand, Indonesia, China and West Africa, carefully stripping bark from the trees to extract a milky white sap which is shaped into sheets and dried in the sun. Between them, these farmers provide 85% of the world's natural rubber supply.

    But this fragile supply is under threat. A native of the Brazilian rainforest, the rubber tree Hevea brasiliensis is no longer grown commercially in the country due to the prevalence of South American leaf blight, a catastrophic pathogen which killed off the country's rubber industry in the 1930s. Strict quarantine controls have kept the disease contained to the South America for now, but arrival in Asia is thought to be almost inevitable.

    In the meantime, farmers elsewhere in the world still face local pathogens such as white root disease and other leaf blights that have made the leap from neighbouring oil palm plantations. Climate change is also exerting its toll – Thailand's rubber production has been hit by droughts and flooding in recent years, with the latter also further spreading disease-causing microbes across growing regions.

    A growing demand for rubber and short supply should be good news for the farmers, as it would make rubber more profitable to grow. Unfortunately, that's not the case. The price of rubber is set by the distant Shanghai Futures Exchange, where brokers speculate on value of this material alongside gold, aluminium, and fuel. "The pricing has nothing do with the cost of production," says Robert Meyer, co-founder of rubber buyer Halcyon Agri. Because of this arrangement, the price of rubber per tonne can vary three-fold from one month to the next, and in recent years has been held at very low values.

    natural rubber is useful but it's also a minority of the actual amount of rubber produced compared to synthetic rubber. Can you guess what synthetic rubber is made out of? That's right! It's fucking oil!

    Glynn Lunney has died.

    Which probably prompts a question like "Who is Glynn Lunney?". Which is sad, because he's one of the greats of the Apollo-era NASA program. One of the great Flight Directors, who helped define the role alongside greats like Gene Krantz and Chris Kraft. Glynn Lunney led the mission control team during key moments of the Mercury, Gemini, Apollo, and Shuttle era, including being one of the people most responsible for saving Apollo 13. A spaceflight legend, someone who truly pushed out the barriers of human possibility and advancement.
    In an interview with Andrew Chaikin, author of Voices from the Moon, Mattingly recalled the impact of Lunney in the immediate aftermath of the explosion, before the flight controllers knew what had happened or whether they could save the crew.

    "Nobody knew what the hell was going on," Mattingly recalled in Chaikin's account. "And Glynn walked in, took over this mess. And he just brought calm to the situation. I've never seen such an extraordinary example of leadership in my entire career. Absolutely magnificent. No general or admiral in wartime could ever be more magnificent than Glynn was that night. He and he alone brought all of the scared people together."

    He said Lunney was able to restore the team's confidence, telling them their first job was to figure out what happened, what options were available and then "we'll just get on with this thing."

    "Glynn walked in there, and he just kind of took charge," Mattingly said. "At that point, nobody would even think of saying anything about disasters ... it's just professionalism at its finest. That was all exclusively caused by one Glynn Lunney. Absolutely the most magnificent performance I've ever watched."

    For those of you who do not see the DnD Cocaine Addiction thread, er I mean Lego thread, Lego today released a very large Space Shuttle Discovery model, the largest Shuttle they've ever made. It is specifically Discovery from STS-31 and comes with a scale Hubble Telescope that can be carried and deployed out of the bay.

    I of course ordered it immediately.
