Voyager 2 Speaking In Tongues 260

dangle sends in an update from the borderland of Sol. "Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that has altered the pattern in which it sends updates home, preventing mission managers from decoding the science data beamed to Earth from Voyager 2. The spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in overall good health, according to the latest engineering data received on May 1. 'Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later,' said Voyager project scientist Ed Stone of the California Institute of Technology in Pasadena. 'It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery.' The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system."

    All the news articles report pretty much the same, digested, not particularly informative stuff. The mission page [nasa.gov] hasn't been updated in a while, the NASA news item isn't any more detailed [nasa.gov], and the last operations report [nasa.gov] was from March 12. But I did learn this from the operations report: they're running the whole mission on less than 275 Watts of power from the RTG units. Wow.

      Reading that operations report I was most impressed by these two lines:

      There were 97.9 hours of DSN scheduled support for Voyager 1 of which 61.3 hours were large aperture coverage.

      and

      There were 62.3 hours of DSN scheduled support for Voyager 2 of which 39.3 hours were large aperture coverage.

      Wow -- that's an incredible amount of Deep Space Network [nasa.gov] time in a week -- and, looking at earlier reports, it seems to be representative of the time used in a typical week. I had no idea that the Voyagers were consuming that much DSN time. I assume "large aperture coverage" means use of the 70m dishes -- also an impressive number.

      That much DSN time must be very expensive.

I think they said it was 9dB below noise even then. The only way they could understand the signals coming back from the probes was by "voting". Basically they would have the probe send the same message over and over and over. The message was then reconstructed by saying Bit #125 was 65 for and 35 against, probably a 1. More than that the

      I remember seeing on a TV program about the Voyager project how serendipitous the timing of the launch was - where you could hop from planet to planet to planet using the gravity well of each planet to jump to the next one. Basically the alignment of the planets when Voyager launched made this possible, and such an alignment isn't going to come around again in our lifetime. So you'd need to build seperate probes to go to each planet, instead of being able to send one probe to many of them.

        Well, no. The outer planet approximate syzygy provided the most efficient profile, mission timewise. You can always gravity sling from one sufficiently massive planetary body to another, using the correct entry and exit vector for the current velocity, it would just take longer to visit them all at this point in time, as you might have to go all the way across solar system to reach the "next" body and then back across again for the next hop.

But you have to understand, just about every mode of travel (actually, I think literally every mode of travel), for a probe, deep space or otherwise, is just some sort of fancy orbit or another. Essentially, a gravity sling maneuver is just using a very particular orbit to gain velocity in the desired direction.

    I have no idea what I'm talking about here, but...

    We now have much better technology, both for getting to space, and for science aboard a probe. For example, even something like the British Beagle 2 Mars mission cost a few million to make, and although it didn't end up returning much of use, it demonstrates how 'easy' such things are (or how hard things are, depending on your point of view, I suppose).

    So I'm wondering, isn't it worth mankind's time to build a (say) £25M long-range probe, like the Voyagers, only designed for the purpose, and shoved into space in some get-there-fast manner?

    I'm sure we can argue about the best use of a limited budget, and what constitutes the best science returned for the spend, for the rest of our lives, but a "cheap" probe sent out every few years to do something a bit random might well do wonders for us and our understanding of the Solar system, let alone the Universe as a whole. I wouldn't presume to say we should do such things at the expense of anything more major, but more to foster some 'experimentation' in space.

      It's probably relatively cheap to build such a probe, and probably also relatively easy to get the funding for a short project like that, but the problem comes when we have to listen to the probe. That's probably expensive and a very long-term project, which are very difficult to get funded(plus they are the prime victims of budget cuts, because such long-term projects are often funded directly outside the normal proposal calls.)

      It would probably cost a good bit more than that to build a long-range probe that has to work for many years before reaching its target. Also, you have to pay for ground stations and personnel to monitor it for the years it takes to get somewhere. We have no magic "get-there-fast manner" today; in fact, the Voyagers were able to do so much because of a once-in-our-lifetime planetary alignment (the Grand Tour). The NASA New Horizons probe is going to Pluto (and beyond), and it will take 9.5 years to get there (and if the launch had been delayed by another few weeks, it would have taken several years longer because there wouldn't have been a Jupiter slingshot fly-by).

        The advances (and readily available advances) in ion engine technology could be used to drive a spacecraft that will accelerate for years out into deep space after chemical boosting ends. Advances in miniaturization and materials science mean that it can be made lighter and carry more instrumentation with better functionality and reliability than those found on Voyager. If we wanted to do it, we can make a new probe that is lighter, has more capabilities, and is sturdier so it can flier faster and stay alive longer than Voyager. Of course, not sure if we still have the desire to be explorers of the universe.

      There isn't really any such thing as a "get-there-fast manner" in space. The distances involved are literally astronomical, and the faster you want to go, the more reaction mass you have to carry, which in turn makes it more difficult to accelerate. (Ion drives don't have this problem, but also accelerate really, really slowly; their main advantage is that they're cheaper to get into orbit in the first place, not that they'll get where they're going any faster.)
