Air Force Space Fence Being Shut Down

New submitter meglon writes "NASA will lose access to important real-time information on tracking orbital debris if the order of Gen. William Shelton, commander of Air Force Space Command, is carried out. The Space Fence, the only monitoring system of its kind, will cease to function on October 1st. 'Deployed in the 1960s, the VHF Space Fence includes three transmitter sites and six receiving stations. It is responsible for approximately 40 percent of all observations performed by the Air Force-run Space Surveillance Network, which includes other ground-and space-based sensor assets, said Brian Weeden, technical adviser at the Secure World Foundation, a nonprofit organization dedicated to space sustainability. ... A full-scale development contract for an updated version of the Space Fence had been expected in 2012 or early 2013, but on July 16, Shelton said the multibillion-dollar project is being held up due to a wide-ranging Pentagon review that includes major acquisition programs. The review is examining scenarios under which the Pentagon’s budget is cut by $150 billion, $250 billion and $500 billion during the next decade.'"

  5. Shelton is playing politics by ebno-10db · · Score: 5, Insightful

    The esteemed Gen. Shelton is playing politics. This is a standard trick. Whenever someone threatens or enacts budget cuts, politicians (and you don't get to be a general without being a politician) start shutting down things which may cost very little, but are highly noticeable or annoying. Obviously this demonstrates how catastrophic it would be to have your budget cut.

      And by "cuts" you mean "a reduction in the initially projected growth". That brilliant government scam where planning to increase a budget by 20% but then only increasing it by 10% counts as a 10% (or 50%, depending on how you phrase it!) "spending/budget cut".

      Anyway, the defense budget is something along the lines of at least $700,000,000,000.00 (700-billion) per year. That is $7,000,000,000,000.00 (trillion) over the next decade. Cutting the budget by $15b/yr to even $50b/yr is fucking meaningless, even if you give them benefit of the doubt that they're talking about real cuts in real spending and not "cuts in increases".

      If they really want to make meaningful cuts, they could knock off the "war against the world" bullshit and save a few hundred billion every year.

  6. Another example of what government is for. by Areyoukiddingme · · Score: 5, Interesting

    This is exactly the sort of thing government is for. It's not like I can set up a radar transmitter in my back yard and sell the data on the open market. I'm not allowed to use that spectrum, and it's blindingly obvious that if I were, so would everybody else, and the spectrum would rapidly become useless to everybody.

    What's the alternative? Sell it to SpaceX? Then make NASA buy access to the data? And Lockheed. And Boeing. And Raytheon. And Virgin Galactic. And Blue Origin.

    But we all know it wouldn't go that way. Lockheed or Boeing would lobby successfully to get to buy it, then charge everybody else on the list for access to the data. And refuse to sell data to SpaceX at all.

    Three transmitters and six receivers costing billions is more than a little absurd, but the job does need doing, and needs doing in a fashion that doesn't set up a wholly inappropriate profit motive and an even more inappropriate opportunity to be anti-competitive. Having said that... Who runs those stations now? Wanna bet it's already Lockheed or Boeing or Raytheon? That'd be why it costs billions instead of the tens of millions it should cost. The wholly inappropriate cost-plus contract with profit motive is already in place. Now all we need is the anti-competitiveness to go with it.

      people would be incentivized to innovate in the area, and over time we'd advance the state of the art

      Innovation in something like this is useless without cooperation (good luck with that) or regulation.

      WiFi and similar open spectrum uses have advanced state-of-the-art radio technology substantially faster than all the prior, protected spectrum uses.

      WiFi runs on the ISM bands, and they're highly regulated, not some sort of Wild West in the aether that you suggest. The ISM bands have limits on transmit power, dwell time for frequency hopping, spreading for CDMA or OFDMA, etc.

      Remember, there is no such thing as "interference" unless the emissions are coherent. Electromagnetic coherence doesn't happen unless you try really, really hard.

      Generating a coherent signal in RF or microwave bands is the easiest thing in the world, it's called a sine wave.

      So the only rule you truly need is to not be malicious.

      Right, who would maliciously interfere with a system that has defense applications.

      Worried about an "arms war" on power output? Good! All the more incentive to create more sensitive receivers, or to advance coding theory.

      More sensitive receivers are the last thing you need when dealing with interference. As for coding theory, we're already pretty close to Shannon's limit. BTW, the space fence has a 768kW EIRP transmitter. Talk about a serious entry into the "arms war". You also need that kind of power for what they're doing. We're not talking about a WiFi reaching 100 feet.

      Do we restrict the number of washer machine detergents that are allowed to be sold commercially, lest "interference" with competitors make the market in detergent too difficult to sustain?

      My washing machine doesn't interfere with my neighbor's washing machine. My 10kW transmitter might interfere with his reception.

    Grow up. If we don't budget for inflation, things are going to suck even more when we get halfway through the fiscal year and realize we don't have the money to get make it to the end. This has nothing to with being a Republican or Democrat and everything with actually trying to plan a project and deliver something to the taxpayer. I realize most households don't have to worry about this on a yearly basis, but both government and big business must if they don't want to fail.

    Now if you want to discuss whether it's in our long term national interest to print so much money that year-to-year inflationary growth is something we have to monitor in our budget process, fine. Or if you have thoughts on how to responsibly reduce government services without gutting either our social welfare or military programs (or both), please share. We need some good ideas, 'cause those idiots up on the Hill seem stumped. But just because you don't like inflation doesn't mean you can live in a fantasy land where it doesn't exist.
