Citizen Scientists Help Explore the Moon

Pickens writes "NPR reports that NASA's Lunar Reconnaissance Orbiter is doing such a good job photographing every bit of the moon's surface that scientists can't keep up, so Oxford astrophysicist Chris Lintott is asking amateur astronomers to help review, measure, and classify tens of thousands of moon photos streaming to Earth using the website Moon Zoo, where anyone can log on, get trained, and become a space explorer. 'We ask people to count the craters that they can see ... and that tells us all sorts of things about the history and the age of that bit of surface,' says Lintott. Volunteers are also asked to identify boulders, measure the craters, and generally classify what is found in the images. If one person does the classification — even if they're an expert — then anything odd or interesting can be blamed on them. But with multiple independent classifications, the team can statistically calculate the confidence in the classification. That's a large part of the power of Moon Zoo. Lintott adds the British and American scientists heading up the LRO project have been randomly checking the amateur research being sent in and find it as good as you would get from an expert. 'There are a whole host of scientists ... who are waiting for these results, who've already committed to using them in their own research.'"

    From the faq (http://www.moonzoo.org/faq):

    Q: What happens to the classifications I provide?

    A: They're stored with those provided by everyone who comes to Moon Zoo. The Moon Zoo team will carefully analyse the results to make sure that collectively we're producing results that are useful to scientists -- keep an eye on the Moon Zoo blog for details. All results will eventually be made public for anyone to use.

    I think the problem here is that it is all take and no give. Categorize our images for us! We'll give you the data "eventually". Crazy idea, how about doing the statistical correlation of multiple contributors in realtime and display that information on an overall map of the Moon so there's some sense of progress at the task.

      It sounds a bit childish, really. How can you say it is all take and no give, and then immediately say that they WILL be giving you the results, but only after it has gone through that pesky scientific process.<WHINE>But I want it now!</WHINE>

      What is the problem with waiting for the right answer? Zakabog has already pointed out that a real time display could be used maliciously, but it could even skew the results by well-intentioned people. If the first person who submits a result for a given region makes a mistake, then the next person who analyses that region might compare their results with the first and "correct" their own mistake. If you use statistics to build confidence in the results then the last thing you should do is tell the subjects what you are currently expecting them to do. That only uses statistics to compound errors.

      Because it is basic game theory? You want the little hamster to continue running around the little wheel you give him a cookie to work for. If he gets little nibbles of the cookie he'll work HARDER trying to get more cookie, thus giving you more work. Hell nobody is saying they have to give them the actual recorded data in real time, just throw the monkey a reward for pushing the button. Maybe something that ONLY shows how you are doing? Surely that would discourage the cranks while giving the hamster a reason to keep running the wheel.

      For those that would like to do a little amateur astronomy themselves, or just haven't heard about it and would like to try some really cool FOSS, give Stellarium a go. The amount of detail it gives is just insane, with my retired NASA engineer neighbor actually able to plan his viewings of Jupiter's moons by running Stellarium simulations beforehand to allow him to find the best times for viewing in our area. It works on Linux, OSX and Windows, is free, and will actually run decently on 5 year old laptops. I'll have to see if the Stellarium guys would like a copy of his latest project, which is using Stellarium to give a visual representation of the objects he is doing spectral analysis of. Stellarium really gives a great presentation and helps the non astronomers to understand what the college astronomy club is doing and the college kids really love it.

      If any of the Stellarium guys read this, great work guys. Your software really is top notch and professional. Oh and he is giving full credit to Stellarium for the visuals, as well as making sure the website is printed on all material. He also made a really nice set of graphic art CD covers for Stellarium, which I'll have to find a place to upload.

      How long has GalaxyZoo been around? Longer than SETI@Home? It's more likely both projects took the hint from how SETI@Home processes data. As another commenter correctly pointed out, these two projects do with spare eyes and brain cycles what SETI@Home does with spare CPU cycles, and all of them rely on having multiple redundant results for the same dataset to verify integrity of the result. It's not exactly rocket science to figure out such a technique would be useful, but SETI@Home has been around for a LONG time, and it's not exactly unknown especially in astronomy circles.

    ...would be to use the statistically-validated user input in a feed-forward image recognition neural network utilizing error feedback that would "learn" to identify the various features of interest. Use edge detection to identify the features of interest (for instance, by number just like a paint-by-number canvas), and have users "identify" what they see. We're talking about invariant scale here, which vastly simplifies the learning process as well as automated feature measurement.

    I was doing this in the '90s using multi-band spectral imagery from LANDSAT with good success. I would imagine there have been some advances in this area since that time.

    Reminds me of the game Mass Effect 2. They had a little Easter egg in there.

    You had to harvest planets for mineral resources in order to have the raw materials for upgrading your equipment. You harvest a planet by orbiting it and sending robotic probes to the surface that presumably bring back the raw materials from their landing sites. When you send a probe down to any planet, your ship's computer (an AI) says things like "launching probe" or "probe launched".

    You can visit the Solar System in this game. If you orbit Uranus and launch a probe there, the computer voice says "Now Probing Uranus". It says that only once and it's the only time it says anything other than the standard phrase.

    There aren't too many opportunities to teach skills which will help people to actually get ahead.

    amateur scientists are not scientists, however.

    Why? According to :

    A scientist, in the broadest sense, is any person who engages in a systematic activity to acquire knowledge or an individual that engages in such practices and traditions that are linked to schools of thought or philosophy.

    Surely if they do this, then it doesn't matter that they aren't paid or haven't been formally trained in a scientific field. There are limits to what you can achieve without an education, but what defines a scientist is the search for knowledge, not already having knowledge.

    You might want to check out some of those pictures before jumping in with speculations.
    Craters are being lit from various dirns, depending on the latitude, longitude and Sun position. This sort of imagery needs a human mind to correctly process it. Furthermore, it's not only about "counting craters", but identifying other interesting features (such as crater bouldery, artificial structures, linear features, moulds and so on). Plus, images have varying degrees of clearness (I found some corrupt images as well, pity you can't report them). The "Boulder Wars" minigame itself is rather interesting too.
