Hi Darren,
So, not really a coherent question but more of a musing-- just
how small an object at what distance can the radars that constantly
track orbital space program junk around the Earth reliably track?
A ballpark figure is ~10 cm diameter for low-earth-orbit objects
out to perhaps
Hi, Darren,
I gather from the phrase about having their orbits decay,
that by Earth orbit, you mean in orbit about the Earth.
Orbits around the Earth only decay because the orbit
touches the uppermost atmosphere enough to cause drag
which, however minute, reduces orbital velocity. It may seem
Hi,
Whoops! The ultimate in late-night dopiness, replying
to my own post.
Some amplifications and clarifications occur to me right away.
First, the object that crosses the zero potential sheet with very little
residual velocity heads straight into the Earth and burns up in a
near vertical
Hi Ron,
I know this was discussed a few years ago on the list but could you address
which might better for meteorites in terms of curation. If I recall, there
was some concern about the padding used in the non-membrane type boxes being
potentially harmful to meteorites. Thanks

Yes -- continued tracking would provide a measure of the object's
drag coefficient. The mass-to-area ratio would be quite high for
rocky material compared to that of most manmade space junk. --Rob
is there a publically acessable inventory of space junk? I can see Mike
Farmer already

As Sterling Webb wrote, if the reasoning he posited follows then there is no
way that tectites came from the moon. The distribution on the earth, the
ablation shapes, stretch forms, and lack of cosmic ray exposure pretty much
eliminate the moon as the source.

Hello
Any of you have received the confirm of the payment

A very interesting discussion but I'm lacking one thing. The shipment
cost for crossing the Atlantic works both ways. Is there anyone on the
European side that would sell small volumes to a collector over here?

Steve, List,
It's why I love tektites, as a puzzle.
Every theory explains some features;
no theory explains all the features of
those little devils.
I regard them as still a wide open
mystery, the only scientific mystery
still going strong after more than 200
years of hypothesis. (The
