Re: [meteorite-list] Terrestrial meteorite

Excellent point, Alan. This is also the reason we should not expect to find Venusian meteorites on our planet. It’s not so much the dynamics of material transfer to Earth from the deeper solar gravity well of Venus – it’s the absurdly thick atmosphere those impactites would have to pass through

Re: [meteorite-list] CNEOS1 2014-01-08 hunt in P.N.G. Harvard physicist Avi Loeb is organizing a $1.5 million expedition

I’m with you, Mike – what the hell?! This is the stuff of tabloids. If people want to find an underwater meteorite, they can search the shore of Lake Ontario for the (much larger than sand) fragments of asteroid 2022 WJ1 that impacted there November last year, or the western edge of Lake

Re: [meteorite-list] Small, earth-impacting asteroid/meteoroid videos now showing up online

Flight direction was azimuth 102, entry angle about 41 degrees from vertical, slow entry velocity (~14 km/sec). There are certainly meteorites on the ground as this was a 1-1.5 meter, non-cometary body. The altitude was 42 km when it crossed the Normandy coastline, and the terminal burst had

Very much enjoyed the Holbrook video, Ruben -- thank you for sharing it! Seems like forever since I've been there, but that red soil is still fresh in my mind. You and your son had a nice successful day of escaping the Phoenix heat, rescuing a dozen 100+ year-old earth visitors from another

Hi Elton, > Any body arriving from space is at least -60�c and closer to -120�c to -180�c > based on > some black body studies of asteroids-- IIRC The temperature for a typical earth-crossing asteroid with a chondritic composition is actually likely to be warmer than this -- perhaps -20 C.

[meteorite-list] Geometry and velocity trump gravity

Hi E.P., Doug's reply pretty much covers it, but I wanted to give you an example so that you can see how your intuition is failing you on this problem. Let's take the case of a slower-than-average asteroid closing velocity encounter of 20 km/sec. And let's say that in the absence of any

Ugh. It joins the ranks of "irregardless". Now that social media is a permanent fixture, it probably only takes a handful of modestly well-connected people to bastardize an existing word into a needless new synonym... I'm becoming a grumpier old man with each passing year, I guess! --R

Hi Mike -- best of luck on your next trip out there. For everyone to appreciate just how hard the searching is there, it would be great if those that have been could provide an estimate of how many hours they spent. Mexico Doug put in a LOT of time out there. Obviously so did Larry, Mike, Laura,

Re: [meteorite-list] Osceola Meteorite is Official!

Congratulations to Mike, Larry, Laura, Josh and Brendan for their aggressiveness in getting to the fall location quickly and their persistence in the face of very unfavorable searching conditions (SWAMP!) It is an impressive feat that anything was found at all, even with the nice radar returns.

Hi Sterling, Note the erroneous, yet predictable association with 2014 RC in these reports. It's Chelyabinsk and 2012 DA14 all over again. Does sound a little like Carancas Take 2, but near a city of over 1 million people -- no fireball witnesses? --Rob -Original Message- From:

Hi Mike/Mike/All, I wondered if I had missed something. As far as I knew, nothing had been found (yet) for the St. Thomas fall east of Toronto. The fall location is pretty well constrained by video (and possibly radar as well), so if anything survived to the ground I expect something will

Hi Kevin, I watched the video yesterday and wholeheartedly concur with you. Very interesting talk by an engaging boffin, and a lot of the information was new to me. I'm very sorry to read of the loss of such an excellent meteorite ambassador at a young age. One correction: Prof. Pillinger didn't
