Satellite photos of possible crash site of MH370
- Sarkie 13y agoIs this really hacker news worthy?
- DigitalSea 13y agoA plane full of people vanished with no sign of wreckage nor anything to go on with tens of thousands of kilometres of possible search area. I'd say this is definitely "Hacker News worthy".
- javajosh 13y agoActually, it's not even newsworthy. This is very similar to the live coverage of car chases that have no real news value - it is sensationalist journalism at it's worst. There are much bigger problems in the world. Heck, car accidents killed far more people in the US alone since this story began than were on that plane (30k/year means 82/day). And this is ignoring new revelations about technology companies being complicit in NSA spying - which is very Hacker News worthy. The Crimean crisis is a good example of a news-worthy story that is absolutely not Hacker News-worthy.
- mr_spothawk 13y agoYeah... and dropping bombs from robot airplanes is still a thing. I'm sorry for a lot of people who are missing their traveling loved ones, but this missing plane thing seems like a crazy distraction.
- Houshalter 13y agoIt's interesting. 99% of the things on hacker news are insignificant and have little impact on the world. No one is saying that this plane is significant.
- caf 13y agoThere's a very real chance that over 200 people were murdered in a single event - if that's not newsworthy anymore then that's a pretty fucking sad indictment of the state of the world.
- Sarkie 13y agoWell I've been downvoted but this is what I'm talking about. I am interested in this, I'm interesting in the technology, crowdsourcing and stuff to find the plane. All I got was a jpg link to a person's dropbox, with no information about today's finding / sighting as opposed to yesterday's. Just a picture of a blob.
- tsarzen 13y agoHacker News seems to be a community of people who are good at solving problems. This is a big problem that needs solving. Over 200 people missing, all with families who are going through a terrible time. I think the HN response to this is a very positive thing.
- weego 13y agoLet's not groupthink our way into believing we are anything more than drivers who have slowed down in the opposite lane to rubberneck at a car crash at this point.
- marshray 13y agoSaaay... is there an app for that yet? (I don't know if I'm kidding)
- shirro 13y agoSure there is an element of that. But there are huge numbers of tech people who are into aviation, radio, satellites, image processing and solving puzzles. I don't want to forget that this is a tragedy for the families involved. But I think it is more technically interesting story than a javascript text editor or the latest crypto currency news.
- omegant 13y agoI´m finishing a blog post on how to use the satellite ping chain (with the consecutive position arcs) and the known cruise speed of the B777 to create a probable route tree over the maps. Maybe it´s not going to give much information (pings are one hour a part and have an error of about 100NM or more), but If it serves to dismiss some parts of the actual ping position band, that would save time to the search teams.
- tom_morrow 13y agohas the ping data been published? to my knowledge, we've seen one arc (from the last ping) that has been split into two parts based on assumptions of maximum and minimum ranges of straight flight at even speed. that's a lot of assumptions.
- auctiontheory 13y agoEven if you're not interested in planes or the souls on them, the technology deployed to find this needle in a large haystack is quite Hacker News-worthy.
- glbrew 13y agoThat is fucking incredible they could find that in the Indian Ocean
- rhizome 13y agoFunny that the US Military and Intelligence technology was never put to use here. Gives you a sense of the ethics in play.
- InclinedPlane 13y agoThere's no evidence that they aren't being put to use. The ocean is big, just because one country's assets found something first doesn't mean others haven't been looking.
- tsarzen 13y agoThis area is close to Australia so the Aussie Military is probably better to handle it.
- NamTaf 13y agoThe US is working on the northern tract. Australia + Indonesia got the southern one.
- 001sky 13y agonever cited =/= never used
- omegant 13y agoI´m just wild guessing here, but if the US had had the MH370 located with a classified radar or satellite, and they know it had crashed, It would be stupid to disclose that technology. They would better use available resources to point the actual position to the search teams (like: "look at this interesting satellite ping arc"), without showing that they knew the position all the time. I´m not telling this is the actual case, but I would do it if I were the one in charge of such technology.
- leoc 13y agoPeople associated with the US government seem to have been giddily feeding the NYT information and theories for days now. If anything the question seems to be how much of what they've been pushing is accurate.
- houseofshards 13y agoQuestion: why are they timestamped March 16, 2014 ?
- dangrossman 13y agoI'd assume that's the time the photo was taken by the satellite.
- glimmung 13y agoI'd have thought that was the date of the image capture - surely it takes an immense amount of time to process that volume of imagery in order to pick out such a thing?
- vidyesh 13y agoSo there is a chance that from the time the image is taken till today it has drifted and the search area would again has to be widen around that location?
- WestCoastJustin 13y agoHere is google maps of the lat and lng's: https://maps.google.ca/maps?q=-43.5834,90.5737 https://maps.google.ca/maps?q=-43.5834,90.5737 [from 1] https://maps.google.ca/maps?q=-44.0302,91.1327 https://maps.google.ca/maps?q=-44.0302,91.1327 [from 2] Based off these images: [1] https://photos-4.dropbox.com/t/0/AAAFoSL9yTdmE2e4_DanfiQ5uk_dIxS6rH4LdM3m2NlzKg/12/278996766/jpeg/32x32/3/1395306000/0/2/DIGO_00718_01_14.jpg/i8-tgdryiKA-RGrF0bqZp6kq1abmJlDkQ-02XKzQQ2E?size=1280x960 https://photos-4.dropbox.com/t/0/AAAFoSL9yTdmE2e4_DanfiQ5uk_...

- jonah 13y agoSomeone's done some fairly high resolution terrain mapping in that area. Plus a small volcano. What's the depth in that area?
- damian2000 13y agoI saw a comment just saying in the thousands of metres.
- justadude 13y agoI read somewhere around 5000 metres, double that of Air France 447. So if that is indeed the wreckage, it will take a while to recover the black boxes.
- davidw 13y agoOk, so unless they were trying to rendezvous with the secret undersea Nazi base on the underwater volcano, it looks like the "steal the airplane" thing either was wrong entirely or went completely awry. So I wonder how it got out there.
- alexeisadeski3 13y agoIrrational terrorist, irrational pilot, irrational/mentally unstable criminal, mentally unstable passenger, mentally unstable pilot, mentally unstable terrorist, or an as-yet-unimagined mechanical malfunction. In no order.
- deleted 13y ago[deleted]
- plicense 13y agoLooks more like sea water reflection.
- munimkazia 13y agoI am obviously no expert, but I expected something more clearer than this. This doesn't look too different from the smudges and discoloration all over the image (are those ocean waves?)
- tom_morrow 13y agoRAAF has gotten radar reflections off the objects in this area.
- deleted 13y ago[deleted]
- munimkazia 13y agoYeah, I read that bit of news after posting my comment. I guess they do account for something when you add radar reflections of solid objects.
- ianlevesque 13y agoMirror for when Dropbox goes over bandwidth limit http://i.imgur.com/UYDAYfz.jpg http://i.imgur.com/UYDAYfz.jpg
- dhimes 13y agoThank you. It's 1200 UTC and dropbox is hosed.
- elleferrer 13y agoDoubtful on this one. I've seen several objects in satellite images of 'significant size' on Tomnod
- blackdogie 13y agoThe MH370 has the following dimensions Wing span 60.9 metres; Overall length 63.7 metres; Tail Height 18.5 metres Just thinking out loud... but a piece that's 24m long, seems a bit small. To me it makes me think of a boat or something similar. I guess the news agencies are happy with this news today, at least they don't have to keep on repeating the fluff from the last few days.
- Cless 13y agoI would never want to speculate, but I speculate that CNN's ratings will be back to their abysmal levels in a few weeks. :)
- tom_morrow 13y agofor something to remain floating after 12 days? maybe a wing with an empty fuel tank.
- mseebach 13y ago60.9 meter wingspan, minus 5.8 meter cabin width, divided by two = 27.5 meters length of each wing. I'd say that computes.
- ars 13y agoIt looks like just waves, or noise. But I think they think it's real because it looks the same on both types of imaging, while the noise looks different between the two images.
- dsl 13y agoThis is spot on. Most geointelligence is not based on a single photo, but a series of captures (multiple passes, wavelengths, angles, etc) and looking at what has or has not changed. US intelligence agencies already have software that does multi-capture analysis like this, and I suspect it was the original source of this "discovery." Usually it is ran on small areas of the ocean (near military seaports or choke points in waterways) or is done at lower resolution to find big objects (aircraft carriers or cargo ships). The computational workload to find a sub-60 foot object in an entire ocean is mind blowing.
- bane 13y agoRight, the two images are off of two different sensors. Probably off the same satellite, one is a panchromatic image and one is probably one channel off of a multispectral sensor. The DTGs are the same (March 16th 2014, 4:16Zulu/12:16 Local). For reference, DIGO is the Australian version of the U.S. NGA. They probably have a bunch of analysts pulling long shifts staring at endless images of ocean along the suspected track.

- triggercut 13y agoAs I mentioned in a previous thread: Distance between: 43:58:34S 090:57:37E 44:03:02S 091:13:27E is 22.72km according to WolframAlpha Images are from DigitalGlobe. A commercial satellite imagery / spatial data provider who provide a lot of imagery that powers Google Earth / Map. Also providing the imagery for the crowd-sourced effort for the search.

- markovbling 13y agoWatched a mind-blowing TED talk by former NASA researcher Dan Berkenstock on the state of Satellite imagery and what we're going to be able to do in the next couple of years: http://www.ted.com/talks/dan_berkenstock_the_world_is_one_big_dataset_now_how_to_photograph_it http://www.ted.com/talks/dan_berkenstock_the_world_is_one_bi... One fascinating use-case is “gleaning a country’s consumption from images showing the number of cars in every one of its Walmart parking lots" We live in such interesting times!
- eitally 13y agoThere was a story on NPR a few weeks back stating that Lowe's (or Home Depot, I can't remember) is already doing this.
- markovbling 13y agoWould love to read more - could you track down the link? It's interesting to think about the problem both from the perspective of the retailer AND from the perspective of the investor. I mean a retailer can just look at their sales volume as an estimate for customer volume but obviously that data isn't available to outsiders. One massive opportunity I've been swirling in my mind is what if you applied image recognition to counting foot traffic. Like if you could just point a webcam at a storefront and automatically count foot traffic - that would be very valuable information.

- chrisBob 13y agoI just watched "All Is Lost" with Robert Redford, and I can't help but think that if you are going to have your boat sink in the Indian Ocean, now would be a REALLY good time to do it.
