Funding Approved for Pluto/Kuiper Probe 224

azpenguin writes "While we discuss the acheivements of the now-silent Pioneer 10, Congress has apporved funding for the "New Horizons" mission to send a probe to Pluto and the Kuiper Belt. Space.com has the story here. NASA had actually fought the idea, but Congress approved the money anyway. Wonder if in 12 years (when the probe is supposed to reach Pluto) the public will be as fascinated with the pictures coming back as much as with the Pioneer and Voyager spacecraft."
In related news, dalewj writes "Seems the team at JPL will discontinue operations on the Galileo Space probe to Jupiter after extended the mission three times. Galileo has been in space since 1989 and has some amazing findings and pictures available on the JPL website. Truly NASA and JPL's best effort to date."

    Did Congress have to force money on NASA? It must be the last sign. I'm going to the bomb shelter.
    • by Anonymous Coward
      I hope the Congress will also give them extra money when the project inevitably runs over-budget... I think the NASA administration was basically thinking that whatever money Pluto-Kuiper express gets, causes an equivalent decrease in other NASA funding. After all, from the Congress's point of view, it's all on the space research account...

      NASA had argued it was not time to go to the distant, tiny world, but members of the planet science community felt it is important to go soon, while Pluto is favorably positioned and before it enters an even deeper freeze in its long, elongated orbit.

      That's from the article. No mentioning on NASA's web site yet.

      In the light of recent Shuttle disaster, NASA is perhaps more keen on getting money to improve safety on Shuttle missions. Just guessing...

    • Did Congress have to force money on NASA? It must be the last sign. I'm going to the bomb shelter.

      Congress is probably doing this to boost morale after the shuttle disaster, and NASA has other priorities.

      It may be a surprise to people, but a Pluto mission is not a high priority for a lot of planetary scientists. There are many other targets that they would like to focus their attention on. The resurrection of the Pluto mission has been largely due to constituents telling their representatives that they consider it a high priority!

      (Also, a lot of people in NASA and the community would rather do the mission using nuclear electric propulsion, since the mission would arrive at Pluto much more quickly. But, that technology is not expected to be mature until the end of the decade.)

      Last year planetary scientists drew up their "Decadal Survey [aas.org]" which is basically a list of planetary exploration priorities for the next decade. (Congress wanted the list, and will probably consider it a "checklist" of what they should fund for the next ten years.) It's subject to changes based on new findings, but it gives a good idea of what scientists want to focus on. They did eventually decide to include this mission on the list. But, they didn't name it the "Pluto-Kuiper Belt Explorer;" they named it the "Kuiper Belt-Pluto Explorer." Kuiper Belt objects in general are considered important, and Pluto stands out merely because it's the largest of that population of objects.

      If you'd like to get a feeling for what planetary scientists want to fly over the next few years, skim that documents. There's some very cool plans in there.

Somebody comes up with a whiz-bang idea for a new weapons system (which may or may not actually do the job) and the DoD says, "Ehhhh, no, we don't really need that, we'd rather spend the money on M16 ammunition for training [or something else equally unsexy]" -- but it turns out that the main contractor for the weapons system is in some influential Senator's home state, and whaddya know, the military is stuck with another white elephant.

      When you are looking at something as incredibly complex as a space flight - 500 million sure isn't much.. over here in Southern California, USA, it is not surprising to see something like a high class home go for something like that.

      I understand NASA was fighting the concept because they felt the money would be better spent on shuttle studies and Mars activity. Not that they did not want the money, they just did not want to earmark it onto a mission to Pluto.

      Consider though the design and launch of such a thing will train another group of engineers in the art of spacecraft design. There are still many of us, now in our 50's and 60's that originally designed a lot of the missions when they were popular in the late 70's, but we are aging. We won't be around forever. And, due to budget cutbacks, a lot of us that have designed spacefaring circuitry are no longer in the industry. As I type this, I pulled a couple of old references I had, reviewing just for the heck of it an Energy Detector design for studying the Van Allen belts and the multiplexer design for the Explorer VII spacecraft launched in the 60's.

      But not many of us lived through that heyday. If a new cadre of engineers are not trained on an unmanned exploratory mission, they get to train on a manned one. I would kinda like them to train and hone their skills on something like this. Back in the old days, we had very little to build our stuff with.. most of it was pre-integrated circuit... like we made them with individual transistors. And we were very concerned with how the transistors degraded with respect to radiation dosages - as nearly all circuits were linear. Today we have much better parts - lower power too- but there are other problems involved that the later parts today are far more sensitive to radiation than those big clunky ones we used. Even before that, our vacuum tubes were immune, for all practical purposes, to EMP - such as static discharges or , God forbid - nuclear artifact. I still use a vacuum-tube oscilloscope when I repair vacuum-tube guitar amps for friends because its front end is immune to the several hundred volt potentials I encounter on the plates of the vacuum tubes.

      I know we just about could tell you how many electrons were in the battery, and we had to make such miserly usage of them. You would probably be surprised at all the tricks those guys went through to conserve every last electron of the flow of current.

      Even our early receivers are works of art. Cryogenic tuners. By building resonators out of superconductors, we could get the "Q" sensitivity high enough to still see our birds as they transmitted on miniscule amounts of energy. The trick was in integration and probability analyses. Stuff like that takes time to learn. And it just about has to be hands-on too. Kinda like learning to walk. You fall a few times.. ( or you set a few rockets back on the ground a few feet from the launch point, launch things into useless trajectories, or launch things that don't work). The phrase that went around during that time was "launching a Maytag"... because the satellites of the day were about the size of a washing machine, and were just about as useful as one if they did not fulfill their intended function.

        I agree with you. While I want, and will support if I can, manned space flight, I think that the unmanned deep space probes are a second strand which actully delivers more value for money. We need to keep that second strand alive. And $300m expected total cost of the mission ($504m cap) is tiny compared to the spending on Shuttle/ISS.

        Apart from anything else, the thinking about designes that *have* to work for 12 years and that you *can't* fix is, IMO, most healthy for NASA. Of course the jury is still out on Columbia, but if it turns out to be tile damage, that shuttle was doomed from liftoff: they had no way of fixing damaged tiles in orbit. NASA has got into the way of thinking that any componen only has to last one flight (Shuttle) or till the next resupply mission (ISS). The rest of the world doesn't work like that: woule you accept a car that needed new tires, an engine overhaul, and a massive safety check after each tankfull of fuel? The rest of the world works either on built to last the lifetime of the object, or at leas a long working life.

        • The prime value of manned space flight currently is in engaging young imaginations. I'm sure we do get more scientific value, more cheaply, from unmanned probes. But kids want to be astronauts when they grow up, not mission monitors for unmanned probes. Obviously most such kids don't become astronauts, but at least some stay in the field, and end up working on unmanned scientific missions.

          The astronauts are a bait for luring kids into the science and engineering professions.

          As they mature, the unmanned missions will become more interesting and motivation. Within my memory, only Sputnik and Sojourner grabbed attention near that of astronauts, with Laika and Voyager (and possibly a Lunar surveyer) following right behind.

        I just wanted to point out that figure is HIGHLY innacurate. I seriously doubt there are any private homes in the entire state of California which go for 10% of that value. $500 million is a lot of money.

        As an example, AOL Time Warner are building a fairly large mixed use development by Columbus Circle in Manhattan. This is a HIGHLY desirable area. The complex has two 55 story towers. As you can see from this story [icsc.org], the entire cost of this building is $1.7 billion, a little more than 3 times the value of this house of which you speak.

        Even in Manhattan, the most expensive real estate market in the nation, I have never seen any residential property close to $500 million, unless you are referring to a while high rise. A full floor, 20,000 square foot condo on 5th avenue accross from central park might cost $50 million, maybe more. But not much.

        Some oversized mansions from another age might fetch $100 million, but they are rarely on the market.

        Anyway, just wanted to make that correction while the coffee has me spirited.

        Good point and I would like to expand a little more. Right now NASA is very concerned with public image. If the public and government views NASA as beneficial then funding will continue to come. Likewise, if NASA is seen as wasting money then future budgets may get cut.

        That being said, NASA would much rather spend this money on something that will show direct results quickly. The Pluto mission will not have any results until 2015 when the probe finally reaches the planet. I'm sure that scientifically NASA doesn't mind going forward with a Pluto mission but from a budget standpoint they would rather have used the money for something else.

It is a long-term investment for the day where we have the resources and technology to travel to other stars and colonize the galaxy.

When the F1 team makes a bad investment, they experience a loss.

They are given a choice: pay up, leave the country, or go to prison. This "choice" is hardly equivalant to the choice made by F1 investors. When NASA makes a bad investment, they experience no loss -- it wasn't their money in the first place!

    Pretty much anything going to the outer system must have a radiothermoisotopic battery aboard, which powers the craft by using the warmth of decaying radioactive isotopes. It's too dark for solar cells out there.
    And to get out there, probes must use slingshot trajectories around inner system planets, usually including Earth. It is conceivable, if highly improbable, that a navigation error (insert unit conversion joke) would cause the probe to impact Earth instead of passing it by.

        During the 50s and 60s - the era of atmospheric nuclear testing - we dumped 3300 KILOGRAMS [lanl.gov] of plutonium.

      At issue is not whether RTGs can be made safe in principle--they can. But after the spectacular failures of NASA over the last couple of decades, as well as getting more insight into the kinds of stupid safety and engineering decisions NASA and their contractors seem to be making, I am not convinced that NASA can put together a reasonably safe RTG. A scenario where the probe blows up some time during launch and a poorly designed RTG just vaporizes seems quite possible given NASA's other failures. I hope NASA's designs will be very carefully reviewed and audited by outsiders because this is a matter that affects everybody.

      Naw, no pork in that. (12 years of sitting around waiting for it to pancake doesn't qualify for a budget allocation.)

    This is just another superiority assertion by the US government. The fact that NASA was against the mission shows how much the government cares about the opinions of those who will be actually performing the mission.
    WTF are we going to find on Pluto? How about that moon that may have a liquid ocean beneath it's surface? (can't remember it's name) It's closer, it will cost lest and happen faster. There's far more potential of finding something interesting.

      Maybe. But it makes sense scientifically (look at the story for the why of it), and what is life but a series of contests? If not for the ideological dick-waving contest in the 60s, there would have been no Apollo.

      How about that moon that may have a liquid ocean beneath it's surface?

      You are correct that landing a probe on Europa (insert ominous Kubrick film warning) would be desirable. However, that's several more levels of technical complexity. You need to deploy a lander on the surface (no atmosphere = reaction engines = fuel = heavy = cost), then penetrating a kilometer-thick ice crust (power = radiothermic generator = heavy, also evil), then deploy an autonomous (the comm delay is measured in hours) microsubmarine equipped with all the instruments usually found in an entire university laboratory. Which in turn require bandwidth. And more power. And very good control software.

      In short, it's probably doable (what isn't?), but it would cost orders of magnitude more than the Pluto/Kuiper probe.

      Going to Pluto does not exclude going to Europa. The urgency of launching for Pluto soon is that Pluto is close now. The longer we wait, the longer it will take to get there. Jupiter's orbit is not as eccentric as Pluto's. We have more opportunities for launching missions to Jupitor and its moons. A flyby of the Jovian system can be a part of the trip to Pluto. It may even be a required part for the slingshot effect. It means that more research of Europa can be done on the way to Pluto. Europa and other targets in closer to Earth are also subjects that other space agencies besides NASA can study. Going to Pluto is, like you said, a way for US to show they can still lead. That doesn't keep any other space agency from going to Europa. Most importantly, Europa is tricky. NASA is about to destroy a probe to protect Europa. Anything any Earth space agency sends there has to be designed to observe Europa without exposing the potential life Europa to danger. We don't to repeat mistakes made on Earth.

    • There is absolutely *nothing* going on on the ISS that could in any way be considered important (or at least remotely worth the expenses). And Pluto/Kuiper Belt space exploration seems to be pretty pointless, too, I agree with you here.

      On the other side, we *have* to make some progress and the only way we know how is "learning by doing". Research should not always be about instant gratification and sometimes solutions to our problems come from unexpected discoveries. There is a very real need to know as much about our universe as we possibly can figure out.

      So, we got to remain active on the space thing or else we won't evolve technologically in that area when it would be rewarding in the long run. Now, why that doesn't mean we establish a Moon and/or Mars colony and do some actual space faring instead of sending countless billion-dollar-probes on suicide missions to return almost no useful data - THAT escapes my limited understanding completely.

      Can someone enlighten me on that one?

      Let's at least build an automated assembly station on the moon (or something like that) so we can launch "mass produced" probes in a more efficient manner. That's because the cost of getting something in space is still a very huge expense because we're way in the stone ages when it comes to propulsion. And in addition, custom-designing and custom-manufacturing of probes is very expensive. Let's just make more, general purpose probes and send have them start from a low gravity place! Let's go to space using a collection of standardized off-the-shelf components! Why not? (This is normally the point where pseudo-experts jump in and rant about complexity of space missions, but keep in mind that the *actual* reason may be because there is a huge industry that has nothing to gain and everything to loose if space exploration would be made cheaper and more efficient. Our civilization is paralyzed by it's inherent corruption, sometimes it seems like we can almost never get anything actually done.)
      • And in addition, custom-designing and custom-manufacturing of probes is very expensive. Let's just make more, general purpose probes and send have them start from a low gravity place! Let's go to space using a collection of standardized off-the-shelf components! Why not?

        Because even though the cost of the probes is high, much of the costs are in the launch and the people manning the uplink to the probe make up the lions share of the costs (just launching can be more than half the entire budget). Since the launches are so expensive any probe launched which doesn't perform is a waste of the money spent to get it into orbit.

        I don't think simply making numerous cheap probes and spending many millions of dollars to throw them into an orbit to often fail would be better on the budget than the current method.

        One way to overcome this is to have NASA focus on reducing the cost/kg of launch systems by pursuing alternate launch methods. Doing this could have a significant effect on both scientific and commercial use of LEO and beyond.
        • Amen to that. Individual satellites are expensive, as a friend in the Canadian Space Agency told me, mainly due to the R&D and construction of one-shot fabrication equipment. Imagine introducing assembly-line style mass production and modular designs to satellite construction. Sure, each individual satellite may be less effective than the current idea of custom-building, but a thousand less-effective mass production satellites may be more effective than a single custom satellite. I'm certain the idea has crossed the minds of others, I'm not claiming it to be original. :)

          And as for launches, what about Earth-based mass drivers? A google search turns up tons of concept art sketches and PhD-level papers. Does anyone have anything easier to understand for someone with a liberal-arts-undergrad level of physics knowledge, with regard to current research on them?

          Offtopic, but it would be nice if there were a dumbing-down checkbox on Google. "I want searches in the range of: 1) Grade school 2) High school 3) College 4) Richard Feynman."

    For those who think NASA is no longer up to the task of building a deep space probe, they should be happy to know that New Horizons is being designed, built, and run by the Johns Hopkins University Applied Physics Laboratory [jhuapl.edu]. APL has a fifty year history of building space craft with exactly one catastrophic failure. New Horizons happens to be the only space craft going to the outer planets that has not been built by NASA.


    Besides the funding issue, the other main problem with New Horizons is the fact that neither of the two launch platforms (Titan 4, Atlas 5) have been certified. They both, however, did launch successfully last fall.

  • The New Horizons spacecraft would be able to detect Pluto satellites down to 0.62 miles (1 kilometer) as it approaches the planet, but finding large satellites in advance would benefit the mission, Stern says.
    Hopefully someone at NASA didn't round that kilometer figure, and then have reporters converting that 1.00 kilometer to 0.62 miles. If it was 0.55 km, it would be 0.34 miles - round the 0.55 km to 1.00 km, then have the reporter convert that 1.00 km to 0.62 miles - aargh!

    It strikes me kind of odd that NASA fought congress about the Pluto/Kuiper Probe. Science is science, space is space, Their giving NASA the money, what's the problem?

    The only conclusion i can come up with is that
    NASA wanted money for something else. That and perhaps congress wanted to get a signal to NASA. "Hey NASA, try building something that'll last for a while, something that you don't have to strip and rebuild every time. It'll give you practice, and with that practice you can put that experience into making better, more reliable shuttles."

    I read that Bush signed off on nuclear engines a bit ago, basically paving the way for a missle defense system or some such. (memory's sketchy, but i believe that's the case) I'm surprised that NASA wouldn't try to develop those engines and incorperate them into the pluto probe. It'd make the journey faster and it'd be a good way to test-drive them.

    In any case, NASA needs a project like this. No doubt, the pioneer 10 misson was very exciting to see. Old tech still kicking and doing it's job way longer then it was expected to. That tells me that NASA really knew how to build things that l-a-s-t back in the day.

    There's hardly any info on Pluto to begin with, and the only pictures we have are fuzzy distant images or artists' conceptions. I'd really like to see actual pictures of pluto up-close-and-personal myself.

    All in all, if NASA works on this hard, and there's no hangups, this probe should last a good long time.

    If I'm not mistaken, there aren't a lot of Al Qaeda space launches. In fact, I see a pretty strong link between hateful regimes and the utter lack of money spent on basic research in any humanitarian or scientific field. A lot has been learned in pursuit of warlike activities, admittedly, but just because we can't bend these backwaters' worldthink to our enlightened ways, doesn't mean we should sit around and wait for them to agree with us before we continue advancing.

    Still, by your logic, I'd at least prioritize. TV, Brittney Spears, novels, the arts, all sports, all cuisine and restaurants, and a few dozen other pursuits are a greater waste of time than scientific research. Live an ascetic life and then come back telling me that the money can be better spent elsewhere. Oh, and your 'net connection... no, make that anything electronic you own... are all forfeit unless needed in a specific mission to combat death and despotism worldwide.

    I hope the above paragraph is the stupidest, scariest thing you've ever read. Your belief has an underlying kernel of truth that can best be laid bare by just thinking of the absurdity of self-denial until everyone else in the world stops being so wrong-headed. Like communism, it's a nobel (a freudian typo?... I meant noble) idea that so far fails in every implementation.

    Developing the 'tech to do it right' without practice is impossible and absurd. Heck, even in modern times, new boat designs have sunk fresh out of the drydock. We explore, we learn, and we stretch into the most unfamiliar areas first because they sometimes reveal deeper questions we didn't even know we should ask. Also we spend years dissecting the failures for lessons and improvements.

    Who the FSCK modded this up (as insightful) to a 5??

    --------

    In a followup, thasmudyan suggests we skip the unmanned cheap exploration and instead set up a mars colony, then contradicts him/herself by suggesting that the space station is worthless in paragraph one and then suggesting that we set up a probe assembly and launch point on the moon. The space station has a shallower gravity well and a more forgiving landing/linkup point than the moon. In other words, it is an attempt to build a staging point for space research. That having been said, if it costs thousands per pound just for fuel to get away from the earth (and about half as much for fuel to land on the moon and relaunch it), how inexpensive will it be to build a semiconductor fab, ship pig-iron, build a machinist shop, have a full suite of materials testing and QA devices, etc etc etc lofted into space? For a long time to come, the most we can hope for is reusability and assembling things prebuilt and tested down here where everything's available and shipping costs are 1e5 cheaper.

    As for thasmudyan's belief that there's potentially a conspiracy to keep space travel expensive, I find all the kennedy-assassination theories more plausible. The cost of escaping earth's gravity is so high, you can pay an engineer for ten years and spend less than lofting him into space. There isn't a techie alive that wouldn't love to see those numbers brought down to a level that makes a week in space affordable. It matters to most of us much more than mere money ever could. Getting thousands of geeks to remain silent about ways to drop those costs would be impossible. Space travel remains expensive not out of a conspiracy, but simply because it is that hard, that iffy, that expensive.

    If you don't believe me, you don't understand the technical extremes we're talking about here. Check again the ongoing postmortem of Columbia's failed reentry, and imagine building any device (no matter how simple) that performs well under these extremes of heat and cold. If it seemed easy, find any 1 thing that performs well both immersed in liquid nitrogen and exposed to a blowtorch. Last of all, imagine building something complex enough to support life for days and still withstand those two thermal extremes, plus a thousand other issues like extreme acceleration forces, radiation, hard vacuum, repeated hot/cold cycling for anything going in/out of unfiltered sunlight, etc., etc., etc. This complexity is why we have the phrase "It isn't rocket science."

    Thankfully, the anti-nuke protest was modded down low enough I only saw responses. Hospitals and highway departments have nastier stuff than the 'nuclear batteries' used to power probes.

    The whole point of PFF/PKE (Pluto Fast Flyby, renamed Pluto/Kuiper Express, and now renamed again) was to launch early enough and travel fast enough to get there before Pluto's atmosphere freezes. It's fairly likely this has already happened, and almost a certainty by the time the probe gets there. Shame this project got overlooked and delayed so many times, since next chance will be in about two hundred years.

    Well, the public was fascinated by Pioneer way back in the day, then they were fascinated by Voyager in the 80s and then in the '90s we were fascinated by Sojourner/Pathfinder, so yeah, we probably will be fascinated by PFF/PKE/whatever they're calling this thing right now. There's always a large portion of the populace that thinks space pictures are cool. Especially kids and nerds, and those will always be a large segment of the populace.
  • I hate to sound like one of those "all this money could be better spent on...." folks, but from a practical perspective, we really need a moonbase. It's an investment in future space exploration, like ISS is supposed to be, but with a purpose. Once we have a decent moonbase we should be able to launch planetary explorations much more frequently and for lower cost. Or so I've been told.
    • Let's see...

      To build a planetary probe you need to be able to build/extract/refine...

      • Rad-hardened chips and rather advanced circuitry
      • Radioisotopes (so you need uranium, which to the best of my knowledge has not been found in minable quantities on the moon).
      • All manner of complex alloys, plastics, and probably carbon composites (so, you want glass as well).
      • Propellant for rockets. There might be useful quantities of water down at the south pole, but it's a real bitch to get (at -238 Celsius or so). Alternatively, you might build a space elevator or an rail gun launcher, but they're both massive engineering projects.
      • Then, you need one hell of a machine shop to make the parts to very high precision, assemble, and test them, all of which will require highly skilled technicians for the foreseeable future.
      • You need mining operations to extract all these things (if you have to ship them from earth, you may as well build the probe on Earth). Carbon is very rare on the moon, so you might well need an asteroid mining operation to get it...

      Until the cost of getting off Earth gets much lower, the capital cost of launching all the equipment and personnel necessary to run the kind of moon base you're talking about is going to be so massive as to be beyond the discretionary resources of even the US government for a while.

  • Wonder if in 12 years (when the probe is supposed to reach Pluto) the public will be as fascinated with the pictures coming back as much as with the Pioneer and Voyager spacecraft."

    This is coming from my astronomy professor at Cornell (who is a major NASA player, directing the Rover missions, etc). He says that Pioneer, while amazingly sucessful in terms of science, was never veyr sucessful to the public because it's camera were pretty crappy. They produced pictures that were not much better than the best ground-based telescopes of the day. Voyager capitalized on this and was given high-def cameras.
    Pictures are among the less important tools on those spacecraft (again, according to a prof), where the radiation scopes, temperature, etc are much more important.
    For a good example of this, look at the first probe to make it to Mars - Mariner 9 (9, right?). It finally reached Mars after years of failures, only to arrive during a global dust storm! The public interest was quickly wanned.
