Hope for Mars Polar Lander? 129

Posted by emmett from the all-these-worlds-are-yours-except-europa dept.
Dave writes "According to this article at MSNBC, it looks like NASA might have received faint radio signals from the Mars Polar Lander which had been assumed lost." Don't get your hopes up on this one; the signal could have come from anywhere, and they're running tests now.

  • Don't get your hopes up. It's probably just an alien or something.
  • Perhaps these 2 signals are Martians attempting to contact us for spare parts??

    Or perhaps the Martians are attempting to build our confidence so that we'll continue sending them "souvenirs".

    Last I heard, Mars Polar Lander was fetching quite a price on Mars' Ebay.

  • The question is not whether NASA succeeds more often than it fails, but whether it is more or less likely to succeed than private space agencies. Or, put another way, whether it costs more or less for the former to succeed than the latter.

    I don't know whether lots of cheap projects beats a few expensive ones (although I suspect it does), but one of the advantages of a free market in space exploration is that those agencies with the right answer win, and those agencies with the wrong answer either cease to exist or adjust their behavior.

    I would like to add that I am not a conservative, and I don't even know what Rush Limbaugh's opinion on NASA is, let alone mindlessly agree with it. My opinion is pretty clearly a minority on SlashDot, but unlike you, I won't ask those who disagree with me to "shut up."
  • Yes..

    However, this will help less people in the end than exploring space will.

    The technologies discovered as a result of space exploration alone have made much much for our economy than the money we spent on it:
    End result: More txable income, and more money that can potentially help these individuals.

    Putting it another way:
    Would you rather spend all of the gov'ts money on the homeless, etc now, or would you rather put money into the police, congress, etc so that society can be better prepared to do this later?

  • The article indicated they were looking for really faint signals amidst the background noise, and that it might take them several days. They should hook up with SETI!

    I for one would be really psyched if SETI popped up and told me it was going to process polar lander signals. At least we know it's out there somewhere.

  • Replying to a commment buried somewhere down below.. As far as I know, the signal is a UHF (400 MHz) very low power (just a few dB above the noise floor) narrow (a few Hz) tone that slowly moves about 50-100 Hz over a about a half hour time span. It could be of earth origin or from any number of other sources. In order to determine if it is from MPL, someone will need to calculate how much doppler shift would be expected from 1) the rotation of earth (this is easy, about 511 Hz, but changing), 2) the rotation of Mars (this is not so easy, because we don't know where on Mars the transmitter is, and that affects the doppler), and the relative motion of Earth and Mars (this is fairly easy) You match up the changes in the frequency of the received signal against the expected doppler changes from relative motion. If it is reasonably close, you are in good shape. If the frequency variations don't match what's expected, you have two choices: 1) It is some other source (most likely).. 2) It IS MPL, but the transmitter on Mars is drifting in frequency (it might, say due to temperature fluctuations, etc. Pathfinder's UHF transmitter frequenciess varied quite a bit over temp) Fortunately, the receiver at Stanford is locked to an atomic reference. You also need to eliminate the possibility that it is some other source (like an out of band (normally in the 300 MHz area) garage door opener that is slowly heating up in the sun, etc. etc.

  • Distributed computing has been around for 30 years now, and all these problems have been solved, you just have to know where to look and how to apply them. Most of them aren't easy to use in a client-server environment like d.net/SETI/ECDL, and so the solutions are of limited use.

    These solutions have been brought to the attention of distributed.net and others, but they find the solutions unacceptable, so continue to use other methods, which is their choice to make. I chose to move on instead.

    There is such a project called Cosm [mithral.com] already well underway to create a system like you describe.

    As for determining "worthy", that is a choice for the user to make, and noone else.

  • See, although that 750 Billion still equates to a great deal of money, stopping the building of weapons of war will not nessarly equate with a gain of 750 Billion for social aid.

    Money has no real value. Generally, every dollar in the economy correlates to something produced. Now, suppose we stop building the aforementioned weapons. Would 750 Billion dollars worth of crops magically spring up out of the ground? Would the infertile land of impoverished nations begin producing bountiful harvests? Of course not!

    If money only is representative of goods produced and labor, then a reduction in goods produced and labor (servicemen) would result in the same amount of money representing a smaller amount of 'actual wealth'. Inflation would rise and the any gains would be lost.

    Of course, that inflation would be checked by a 750 Billion dollar slowdown in the economy. Estimates say that there are 2 Million servicemen in the United States military (I don't have any global statistics, but I'm sure it is astronomical). Then there are the companies surviving on defense contracts (Lockheed Martin would be closing its doors (that's allot of high paid engineers hitting the streets)).

    Another thing to keep in mind is all of the technological advances that sprung out of military spending that have helped the world (Microwave ovens, rockets, GPS, interchangeable parts, aircraft, and. dare I say, computers). None of this would have existed were it not for military spending.

    Stopping world hunger (which, I presume, is what you are referring to when you say the world's problems (anyhow, it is by far the most immediate and fundamental) is a much too complicated battle than could be won by 'brute force' economics. It must be won by a delicate balancing act between diversification of resources and economics.

    Sadly, there is no 'magic bullet'.

  • As the world hovers on the brink of losing a multimillion dollar space exploration vehicle, a faint signal crackles through the radios at NASA. Dan Caldwell, head of Receiving Extremely Faint Radio Signals from Millions of Miles Away, sleeps heavily by his console. His dog, Lassie, however is instantly alert to the sound, and dutifully awakens her owner with a bark. "what's that, girl?" Dan says sleepily. "WOOF, Dammit" "What's that?" "TIMMV (Terrestrial Interstellar Martian Mission Vehicle) is stuck in a one mile deep, one mile across canyon that we managed to completely not see while we were surveying the martian landscape for optimal landing sites?" The dog lays back down and goes to sleep. Do we really want these people to handle our space exploration? sheesh...im going to bed.. Meanwhile, a group of echelon scientists are working around the clock to determine where Lassie learned such colorful language.

  • I wouldn't call it hope. If its a false signal, it still is lost/crashed. If its an extremely weak signal, it means that the antenna (and most likely other components) have been heavily damaged.

  • I thought they had given up hopes of listening to that mofo. Obviously, NASA is making every attempt to recover every bit of whatever they send out there. But hey, when everything costs $150 mil, then I would be trying everything I could, too.

    This whole Mars thing is great, because out of 10 projects sent there, only 1.5 have been unsuccessful. The 0.5 left would be classified as a "successful failure" but I wonder what the Polar Lander can do now.

    OTOH...

    I wonder how much support you could garner for a kind of meta-client. Write a basic framework that could handle any kind of idle-eater, and then let users decide which ones to run. Users could, for example, be provided with a list of potential interests (e.g. Internet Prime Search, Seti, NASA stuff like this, etc.) and just tickmark the ones they wouldn't mind doing.

    Let the client grab new processing modules for any task that can be modularized, and you turn the internet into an enormous, general purpose computer.

    Of course, the potential for abuse, especially through someone sending their own processing modules, masquerading as the server, would crop up. But if, for example, each module was gpg-signed, this wouldn't be such a problem.

    All I know is that this could really open up some incredible power to all sorts of research projects that just can't happen right now for lack of resources. I know *I* would download it.

  • This is OT, but the money that NASA spends is a small percentage of what the US government spends. If it helps ppl on Earth (and not those in the USA as you wish) then it is money well spent. But my main point is to hopefully put things in perspective.

    We just had a good storm here on the east coast of the US. The US government closed down in DC for Tuesday (and I believe for Wednesday). The total cost for the two day shutdown for the Washington,DC area is about $120M. You could practically send up another probe for that type of money.

    You mean like, say, VMWare [vmware.com]? Hell, isn't a virtual machine the ultimate meta client? Running, of course, a streamlined Linux OS. A Java VM is another option. Both take performance hits.

    I was brainstorming around this general idea a while ago. The general problems I came up with were:

    • Security of the host system.
    • Authentication of the client application.
    • Criteria for determining "worthy" projects.
    • Billing, accounting, or payment tie-ins.

    First off, distributed computing is very successful in some closed environments -- POW (pile of workstation) clusters in campus environments are common. A friend at a New Zealand biotech firm distributes Linux boot floppies. At the end of the "work" day, their Windows boxes are rebooted with this floppy installed, a Linux machine springs into place, and a gene sequencing client starts munching away -- the real work day. Similar schemes are pretty common.

    In a broader environment with less control the problem becomes tougher. The host machine needs to have some guarantee of security. The client should also be reasonably secure and non-spoofable. There needs to be authentication.

    In order to select for worthy (or billable) projects, some sort of voting scheme needs to b e implemented. If this is based on dollars or bill-backs, the small size of the individual contributions, with per-month CPU rental rates rating < $20 for new equipment (essentially the lease cost for hardware) -- means that this is not a way to get rich.

    Factor in latency, bandwidth, lossage, and storage factors. It's a complicated problem.

    This isn't to say it's not addressable. Distributed Net [distributed.net] appears to be actively researching several of these areas. It's quite possible that all that idle CPU time will one day be put to use. But not real soon now.

  • The original mission of the 'Pathfinder' was limited in duration to its batter power. Even with the solar panels, it couldn't power the equipment and heaters to keep it running more than a month or so.

  • Check out the poll on the same page as the article. The question is, "In light of the Mars failure, what's your view on space spending?" As of this writing, 65% of the respondants voted to increase NASA's budget. Such is the nature of government.
  • According to the reports the probe entered a state of "safe mode", probably like a protection sequence in case there is an error or any damage. In all likely hood it is possible that it could come out of it at a preset time. A weak signal might just indicate damaged components, or maybe something they did not encounter at all?
    In any case, if it is the lander they could boost the gain here on earth and still make the thing useful. They might be able to figure out what went wrong.

  • The reason "failure is good for NASA," with regards to the poll, is because in general the only people that feel space exploration is a waste of money are the people responsible for creating the government's budget plan.

    The U.S. populace continues to support space exploration, and continues to press for further expansion of the space program, and the government promptly ignores them and slashes a few tens of millions of dollars more out of NASA's alloted budget.

    One problem is that $20/mo is about the rental cost for, again, new hardware. The average age of installed base is probably in the range of 2-4 years. My own PII/180 is adequate for my own tasks, but is about 1/3 to 1/4 the speed of a new system -- would I get only $5 to $7 per month of credit?

    The pricing angle is one that I'm not settled on -- depends on supply and demand. If companies could instantaneously add and remove compute power, the base HW costs would probably work out about right. The convenience value of being able to add and remove capacity rapidly and without physical deployment requirements might make higher rental rates possible, but you've also got to figure overhead and a percentage for the business itself. The business case is slim. Possible, but slim.

    YANI -- Yet another harebrained idea: the emerging ASP market coult be modified slightly around this concept. Essentially CoWs, but rentable. This is a more likely doable option IMO.

    What part of "Gestalt" don't you understand?

  • Thanks. Cool reference. I'd run across the Netrek authentication concepts a while back. There's also a paper on doing authenticatable distributed computation at the COAST [purdue.edu] website somewhere. PS format, IIRC.

  • Now there's an idea!! Why don't we do this on occassion? Just send everybody in D.C. home for two days without pay, and do something cool with it - send up another probe, contribute to a worthy cause, or just otherwise make a solid contribution to funding research toward making life happier. I'm sure DC would keep being DC, and the rest of the US could use a two day break from them a couple of times a year...

  • Uh, no... I would guess that some one is setting up Unitek to be mailbombed and DoS'ed.
  • FYI - this was actually funny the first time I saw it today when it was correctly formatted. This is just lame. (hint, use blockquote tags)

  • One of the possible problems with the probe is it may have been too cold for the batteries to function. If that is the case, now that the pole is moving out of winter the batteries may be able to function again.
  • Wow. Your numbers must be true then. 2/3rds? What a coincidence! There's a well documented web page out there that says 2/3rds of the girls at Ohio State think I'm hot. The other third are insane. Trust me, someone posted it!

    emmet sez..

    Don't get your hopes up on this one; the signal could have come from anywhere, and they're running tests now.

    Yes. It could be from some typically mundane source like outer space aliens. In my opinion, there should be regulations to restrict interstellar subspace communications to a few designatede bandwidth. With all the noise in this solar system I have difficulty contacting Command Zorb (weebles upon him!) in the Delta Quadrant. How am I supposed to receive my orders clearly when my brainwave transmissions are suffering from interference? For example, yesterday I was speaking with Commander Zorb (long may he froop!) in my head when an outer space alien interrupted with a comment that I should kill my family.

    Yes! We are all individuals! I'm not!
  • Go directly where it is : here [slashdot.org]
  • Suppose the main antenna and/or relay is the only broken elements.

    If we can anyway tell when there is signal/no signal, that means we can also try to set up a rough binary information transfer...

    And maybe, if that signal was really from the PL, we can get some information from it.

  • The press release from the JPL [nasa.gov] says that, now that they know what the signal should look like in the data stream, analysis should only take a few days. It would take considerably longer than that to modify the SETI@Home (or distributed.net, etc) clients and distribute them widely enough to be useful.

    This isn't a bad thought, though -- perhaps in the future, projects such as this actually could make use of distributed processing on the internet. However, this strikes me as unlikely because, considering how cheap processing power actually is these days, projects like this one don't generally spend very long on any one problem, and so benefit greatly from being able to change the running algorithms at will.

    Anyway, I wish the JPL teams the best of luck on this one. Who knows, maybe they'll even figure out a way to fix the relay to Global Surveyor. At any rate, it would be a great relief to everybody involved just to know what actually went wrong with the mission.

  • Except in our case it would be called P-ander.

    Hail P-ander!

  • Well, if the signals they recieved didn't come from the lander, WHERE DID THEY COME FROM? There had to be something intelligent about the signal, or they wouldn't have announced it. Do you think that they would release a statement getting excited over static? That signal must have either had a subcarrier that they use, or some kind of intelligent data that caught their ear.
  • ....32.rf... OUCH ...3..2x.?....
  • Yeah, someone who monitors the posting of these messages ought to start a little traceroute and inform the correct authorities.
  • That is clearly not what I wrote. It must be easy for you to win debates when you get to make up bad arguments for the other side.

    A private space agency profits when it succeeds, and loses money when it fails. Would-be investors have an incentive to figure out which is more likely to occur, and the agency has an incentive to make sure it succeeds.

    NASA loses other people's money when it fails. To an individual taxpayer the cost is very small, and he has virtually no choice over how that money is spent, anyway. As a consequence, it is not worth his effort, time, or money to monitor the details of what the agency is doing.

    These are reasons to prefer shrinking NASA to growing it.
  • The Dish has a wonderfully colorful history, shrouded in the early days of the Cold War. Publicly, it was built for 6m radio occultation experiments for the Mariner Venus probes in the early 60s. The transmitter is a truly awesome entity, which was sadly rusting away the last time I saw it a decade ago. The single final amp tube was water-cooled using four truck radiators, and even the feedline was water-cooled -- as low as the losses were, there was so much power going through that waveguide that heat losses could (and did once) melt it.

    The Dish also has a long history of satellite rescues, including one of the OSCAR ham satellites. As the Valley grew up and started becoming a broadband RF noise source, the Dish fell somewhat into disuse until a group at STARLAB devised a signal washing system (nice work Ivan and Co.). It has seen quite a bit of astronomical work since.
