Voyager 1 Sends Messages from the Edge

dalmozian writes "NASA's Latest News about the Voyager 1 is being run on Sci-Tech. The Voyager has passed into the border region at the edge of the solar system and now is sending back information about this never-before-explored area, say scientists at the University of Maryland. From the article: 'Voyager 1 and its twin spacecraft Voyager 2 are now part of a NASA Interstellar Mission to explore the outermost edge of the sun's domain and beyond. Both Voyagers are capable of returning scientific data from a full range of instruments, with adequate electrical power and attitude control propellant to keep operating until 2020.'" The proof of crossing the termination shock was covered earlier this year but now we can see the actual data.

      The only "mystery" is people being unwilling to understand the sheer number of men it took to build them. No one questions how the Great Wall of China was built, and it is a much more impressive engineering feat than the pyramids.

      Isn't the Earth-Moon system also technically a binary planet?

      Yeah, some astronomers have suggested that. The problem is, as explained in an adjacent article, the term "planet" has never actually had a proper astronomical definition. There's an IAU panel working now to settle the terminological debate. The current proposal is that "planet" by itself be delisted as an astronomical term. They suggest that a modifier be required before "planet".

      Part of the debate is that there's a significant crowd that objects to classification terms that depend on things that are not properties of the object. Or, at least, we should make a strict distinction between terms that describe an object, and terms that describe its relationship to other objects.

      This would mean, for example, that the question of whether Luna and Titan are planets or moons would be answered "Yes." They are planets that are orbiting another planet as moons. But others insists that they won't allow something to be both a planet and a moon.

      The Earth-Luna pair is an interesting case, because it's somewhat borderline. The common center of gravity is inside the Earth, but close to the surface. Another interesting bit of trivia is that the Lunar path around the Sun is everywhere convex (relative to the Sun) This means that it's more accurate to describe Earth-Luna as a pair that share an orbit around their common primary, rather than one orbiting the other.

      But it's all rather silly, because there's no agreed-on definition of "planet". The term just refers to a historical list that is looking less and less relevant with time.

      Anyway, stay tuned. Maybe the IAU will settle the matter, at least for those of us who consider their opinion important. Most likely, they'll just discard the term. If they do define it as an isolated term, the result will be a rewriting of the list of planets in the Solar System, as the current list is starting to look somewhat inappropriate.

      It's too bad that the universe isn't cooperative enough to fit into a classification scheme that someone invented a few centuries back.

    I actually got to see this data presented at a cosmic ray conference this summer. There are a few things you have to realize:

    • This is the only astronomical shock we are able to study closely
    • There are a lot of things we don't understand about shocks
    • Voyager 2 is still working, with better instruments, and will reach the termination shock early
    • We're seeing things we never, never expected


    For instance, on the last bit, we expected to see cosmic rays from the termination shock, because shocks accelerate particles. We see them. But they don't appear to be coming from the shock. They're coming from somewhere else that we don't know. We see another set of cosmic rays (with a different spectrum) that we don't understand at all - we just call them "anomalous cosmic rays."

    Also, inside the heliosphere, Voyager 1 kept crossing magnetic domains (so a needle on a compass would swing back and forth) periodically. It was expected after the shock that those domain switches would keep happening, much much faster. That didn't happen. In fact, the domain switches stopped. We don't understand why. That doesn't make a lot of sense.

    This is our only probe and our only example of a large astronomical shock. It's full of information about how the Universe produces such violent outbursts like supernovae, or gamma ray bursts. We need to keep studying this.

      Anomalous cosmic rays are particles accelerated at the termination shock. They are anomalous inasmuch as they have a different spectrum to the incredibly high energy cosmic rays that come from outside of the solar system. No-one knew what caused these particles originally so they were labelled "anomalous". In fact the unrolling of the spectrum of the ACRs was critical evidence that we had reached the TS. And I'm not sure what you mean when you say the energetic particles are "coming from somewhere else that we don't know"?

      Whilst there's lots about the TS that is suprising and exciting and that we don't understand, it is not quite as mysterious as barawn makes out.

      As for Voyager 2 - it has a fully working plasma instrument that will give direct measurements of the plasma temperature, density, pressure, flow speed and so on, something we didn't have for V1.

      I was not involved in the decision to cancel funding for Voyager, but I have had some involvement in the process that NASA uses to review missions and decide which spacecraft operations to keep funding. I'm relatively low on the totem pole, so don't blame me if you don't like the funding decisions NASA makes. I don't always like them either!

      I suspect that some of the issues considered were the numbers of new publications from Voyager data compared to the more recent missions, the status of Voyager's instruments, and the ability of our ground stations to pick up signals from the spacecraft. These issues come up with any older NASA mission and are not unique to Voyager.

      I agree that the data from Voyager about the termination shock are important - this was one of the reasons why funding to operate Voyager has continued as long as it has. However, there aren't really a whole lot of data from the termination shock, so a relatively small group of people are studying this data. This means a lower science return for the money spent, at least in terms of the numbers of papers published using new Voyager data. Some of the more recent unmanned spacecraft are also in danger of being cut, and there are still hundreds of scientists around the world working on data from these missions.

      While it is true that Voyager is providing a unique data set, the data from this spacecraft are from older instruments that may not be running at their optimal capacity. We have missions with newer, far superior instruments studying other regions of our solar system right now. So which does NASA choose to keep operating - the older spacecraft with limited capabilities, or the newer missions with greater potential for science? When you look at it this way, it doesn't seem quite so bad to cut funding for Voyager, even though the recent discoveries from Voyager have been very newsworthy.

      One of the other posts claimed that the termination shock is the only astrophysical shock we can study so we need to keep funding Voyager. It isn't entirely true that the termination shock between our heliosphere and the interstellar wind is the ONLY astrophysical shock we can study. A shock in a space plasma is a shock no matter where it is, and they all are pretty similar. The same physical processes happen in coronal mass ejections from the Sun, at the Earth's bow shock, at the bow shocks of Saturn and Jupiter, and near the heliosphere's termination shock. The main differences between these shocks are the magnetic field strengths and the scale sizes of the shocks. Other than that, the physics is pretty much the same. So NASA has to make a choice - spend the money to support research on all of these other things, or spend it to keep an aging spacecraft going to study just one region of space.

      Don't get me wrong - I'm sad to see the Voyager mission winding down. It
      would be great to see more discoveries from beyond the boundaries of our solar system. Unfortunately, we can't keep Voyager going forever. We just have to leave some discoveries for future generations.

      No. Absolutely not. The termination shock is huge. It's something like ~150-200 AU across the heliosphere. We have no idea what the structure of a shock like that is. I said it's the only astrophysical shock we can study, and I stand by that - it's the only astrophysical scale shock we can study. CMEs are far too small.

      The fact that we're seeing things we completely didn't expect should tell you that. We do not understand the acceleration of particles at a shock. Coronal mass ejections happen in a few seconds. The termination shock has existed for millions of years. These are very different phenomena.

      Cancelling the funding for Voyager right now is simply idiotic. We just found out that a lot of assumptions we had about the termination shock are wrong, and there's another probe heading there right now!, with more instruments!
