Matteo is a never ending distraction. I think he loves all this attention.
I'm done with it, no matter how infuriating. He is a hopeless thing that will
feed on everyone he can. I have to admit that i'm so angry that i've ignored
all the great things I came here to learn and enjoy today just to
Ron makes a great point here. It follows that almost all meteorites on
Mars should produce some kind of crater and most would be vaporized...
Does anyone out there know what the terminal velocity ratio is for Mars?

Bill,
I would have preferred this were OFF LIST:
I NEVER mentioned the military (something I consider way
out of order when our men and women have their lives on the

This is a layman's answer:
A comet only looses substantial matter when close(r) to the sun. So yes,
after some time he disintegrates, but this can take a long time,
especially when he's big. Some comets' orbits are even disturbed in a
way that they drop into the sun - they are gone then,
Dear List,
I was pondering what Ron had to say about hypersonic
impacts and other comments.
From the Wilemette, Alnighito and Hoba meteorites,
it's safe to say the largest non-hypervelocity
impactors on Earth are about ~10 meters, as an order
of magnitude.
To avoid hypervelocity impact, the

Hi Francis,
It's nice and passes the smell test, and I now realize we are looking for a threshold size limit for survival. I would support your ballpark figure and combining some of the ideas I mentioned in the prior comment on the subject, add that the slowing frictional force taking the initial

Hi 'list' ... Has Begga (LL3?) been formally classified yet ?

Hi,
A comet is presumed to have spent most of its billions of years out in
the cold beyond the planets. Something -- a gravitational encounter --
disturbs its orbit and it falls into the inner system, probably by stages,
with Jupiter as a big player in this game.

A few comments (perhaps naive speculations) on statements by Francis

Just to add, while a landing site inside a newly formed crater may not be the best place to hunt for tektites, perhaps Martian tektites will go a long way to further supporting -if not by Spirit or Opportunity- someday) that Earth tektites are cased by meteoritical impacts...and perhaps tektites
