To not bury the lead: His team studied data the government made available from military missile tracking systems, which conveniently also false-positives on asteroids. There was one in 2014 which slammed into the Pacific Ocean at a speed at least twice that of the speed stars around us move relative to the sun, which makes it likely to be extra-solar. Based on that speed & how much burned upon entry, they concluded its material must be tougher than iron. They're planning an expedition to the oceanic area around Papa New Guinea, mostly funded through private donations, to recover the object.
- caseyohara 4y agoLede, not lead.
- harmonious 4y ago"You should have written 'lede' instead of 'lead'.", not "'Lede', not 'lead'.".
- caseyohara 4y agoI wrote it that way only to mirror the other corrective comment that was posted before mine.

- adamzochowski 4y agoThe world says "leading news story" and therefore "burying the lead". Lede is an american thing. Parent could have been a british or canadian neighbour with their british colourful spelling.
- MichaelCollins 4y ago> The spelling lede (/ˈliːd/, from Early Modern English) is also used in American English, originally to avoid confusion with the printing press type formerly made from the metal lead or the related typographical term "leading". Huh.
- 015a 4y agoI promise, I'm not, I'm just dumb.
- samstave 4y agoI too choose this guys dumbly leaded comment (Lead makes you dumb)
- googlryas 4y agoIt's actually more about the lead paragraph, not the leading news story. If you bury the leading news story, that would imply putting it on page 13 or something. Buring the leading paragraph is putting the most important information at the end of the article where fewer people are likely to encounter it.
- 867-5309 4y ago>To “bury the lede” (sometimes spelled “bury the lead”) means to delay sharing the essential information in a story, and beginning with secondary details instead. The term originated in the news-writing world but is now applied widely in all fields of writing. "lead" in this context is pronounced led not leed
- highwaylights 4y agoProps for your correct spelling of colour.

- TechBro8615 4y agoMaybe OP was making a pun about what could be buried in the ocean.
- lisper 4y agoPapua, not Papa.
- nine_k 4y agoI can imagine their disappointment if all they recover would be a few tons of platinum, iridium and such. /s
- elcritch 4y agoAnd here I didn't even consider the chance that it was an elaborate ruse to grab a punch of rare-earth metals. Apparently my heavy diet of sci-fi and techno thrillers hasn't trained me well enough yet. ;)

- ajnin 4y agoThese are not rare earths, rare earths are a family of chemically similar elements close together in the periodic table that are not actually that rare geologically. Platinum and iridium are just rare elements.
- jonathankoren 4y agoI love how this would be the exact inverse of the Project Azorian. https://en.wikipedia.org/wiki/Glomar_Explorer https://en.wikipedia.org/wiki/Glomar_Explorer
- SavageBeast 4y agoTheres a great documentary about that by the name 'Azorian - The Raising of The K129 on Amazon' - I think I bought it for $1 - you should give it a watch if you haven't yet.

- headelf 4y agoIf it's tougher than iron, why are they planning to use a magnet to retrieve it?
- ericlewis 4y agoI suppose because they didn't say it was less magnetic than iron?
- jahewson 4y agoAll other metals are less magnetic than iron.
- system2 4y agoTougher doesn't make it less magnetic.
- eloff 4y agoThis seems a reasonable question to me, not having read the article. IIRC from grade school days, only a few metallic elements are magnetic. Iron, nickel, cobalt, and some rare earth metals. That was a long time ago and doubtless oversimplified, but please do enlighten me why it would be expected to be magnetic? It seems like they must still be assuming it's largely made of Iron.

- giantg2 4y agoIsn't it sort of funny that they think the asteroid might be some new material, or at least something tougher than iron, yet they are planning to use a magnet to pull up pieces? What happens if it's non-ferrous...
- texasbigdata 4y agoUsing a magnet seems like not a top 5 idea someone would have.
- cplusplusfellow 4y agoSay you find the asteroid on bottom of ocean. What sort of hoisting apparatus do you propose we use to bring it ashore?
- mecsred 4y agoClaw. Bucket. Reinforced net. Submersible ROV. Trained sea life. Anything that's not a magnet.
- hhh 4y agoArcade claw, with coin slot and all.
- adolph 4y agoToo bad they scrapped the submarine lifting grapple equipped Glomar Explorer https://en.wikipedia.org/wiki/Glomar_Explorer https://en.wikipedia.org/wiki/Glomar_Explorer
- Flankk 4y agoCore sample via remote controlled submarine. Magnets sounds goofy. I suspect he knows something we don't.
- giantg2 4y agoSupposedly it's in pieces from the impact. Small samples would be fine to locate and collect via ROV with a metal detector on it to check below the silt. If they want mass extraction after that, then potentially a form a dredging could be used (vacuum and filter could work to leave the sand and silt on the bottom).
- ineptech 4y agoI get the "from outside our solar system" part, and it seems believable that sensors designed for missile tracking would get enough telemetry info to establish that. But the "tougher than iron" part? Based just on how much material was lost during atmospheric entry, as reported by sensors not really designed for that purpose? That's a tough pill to swallow. It would be really interesting to hear more about how much this asteroid differed from others measured by the same equipment.
- wiml 4y agoI have a dim memory that missile tracking systems pay close attention to how fast an object decelerates when it hits atmosphere, as part of distinguishing real warheads from decoys. Maybe you can use that data to estimate how fast a rock is eroding að it falls.
