[meteorite-list] Mars moon got its grooves from rolling stones, study suggests

My favorite part:

The simulations showed that boulders hit that lip and take a flying leap over the dead spot, before coming down again on the other side. “It’s like a ski jump,” Ramsley said. “The boulders keep going but suddenly there’s no ground under them. They end up doing this suborbital flight over this zone.”

Re: [meteorite-list] Minor planet impactor witnessed over Botswana

[Thomas Kurtz via Meteorite-list]

Hi Mike, hi Rob,

 

thank you for this outstanding news.

  Video seems very promising for a meteorite fall.
 


This is the 3rd meteoroid detected prior of the fall. (See Wikipedia)

 

1. 20081007 Sudan_TC3_Almahatta Sita

2. 20140102 Atlantic Ocean NE to Brasil 2014 AA

(3. 20151113 Sri Lanka WT1190F --> 11,3 km/s reentry of translunar injection module from Lunar Prospector, 1998)

3. 20180602 Botswana ZLAF9B2

 

Looking forward to the next one :-)

 


--Thomas

Hey Rob,

Nice find. A few more reports have come in, one with a nice video.

https://www.amsmeteors.org/members/imo_view/event/2018/1924

The tractor shed seen in the video, I believe is just 200 meters south
of the witness reported location. Looking at the surrounding buildings
I'm pretty sure this is it. The lat/lon for the building in the video
is: -26.743427° 26.222917°

Thanks,

Mike

Re: [meteorite-list] 3D laser scans of meteorites

[Thomas Kurtz via Meteorite-list]

Hi Svend,

 

excellent 3D-laser scan work and detailed descriptions !

I´m a big enthusiast of 3D-printing.

Especially future 3D printing in space. Like for spaceships, probes, etc. made with powder of catched asteroids.

Betreff: [meteorite-list] 3D laser scans of meteorites

Dear list,
 

While I'm still convinced that the most meaningful and conclusive approach to capture individual meteorites is by conventional photography, I've been experimenting a bit with 3D laser scans recently.

 

Along the way, I gathered some gigabyte of STL data, but only used it for visualization purposes so far. See some examples here:

 

http://www.meteorite-recon.com/home/meteorite-documentaries/3d-meteorite-scans

 

Among others I chose two oriented chondrites for the project and came to wonder whether someone here is in the business of aerodynamic flight simulation. My question is, if the data gathered can be used to determine ablative flight orientation for a given shape. Perhaps there is an established test model with relevant parameters available? 

 

Thanks for your interest.

 

Svend

[meteorite-list] Volcano Eruption in Papua New Guinea 29-Aug-2014

[Thomas Kurtz via Meteorite-list]

Hi All,

there is a new MUST SEE movie of a volcano eruption.
It´s not directly meteorite related, but shows high velocity effects on debris, 
air and cloud condensation around.
The velocity of the stone-cloud might be near 1km/s.
