More about Meteors in Space:
* Dr. Bill Cooke of NASA / MSFC generated a table of 12 predicted
meteor showers on Mars in NASA/TM-2001-210935 "Mars Transportation
Environment Definition Document" dated March 2001. His table (table 2-8,
Page 2-13) is in section 2.3.4. I believe one of the showers corresponded
to the time of the alleged meteor captured by the Mars rover.

* Crude camcorder observations of a few 2001 Leonids were taken by the
International Space Station Expedition 3 crew.

* I also believe that one of the Voyager spacecraft recorded a meteor
in Jupiter's atmosphere but I don't have a reference for it. Then of course
there is Shoemaker-Levy 9, the BIG one: More than theory there!

Hello guys,
Waow, lots of questions!
Let me start me the easiest: the image was processed by M. Lemmon and J.
Bell, so I can't answer any of these question without taking the risk to be
200% wrong ;-)
About meteors on Mars:
-yes there were some studies about meteor showers on Mars. See:
http://cdsads.u-strasbg.fr/cgi-bin/nph-bib_query?bibcode=2004A%26A...416..78
3S&db_key=AST&high=425d6798a828937
http://cdsads.u-strasbg.fr/cgi-bin/nph-bib_query?bibcode=1999P%26SS...47.147
5C&db_key=AST&high=425d6798a811332
and for Venus:

-yes the idea to observe martian meteors "from above", and was already done
on the Earth during the Leonids by the satellite MSX (see Jenniskens et al.
02)
-all these works are theoritical (of course)
-yes the entry velocity of meteors on Mars are lower than on Earth, because
Mars is farer away from the Sun than the Earth (just a statistical effect of
course).
-we know the observed streak is not Viking Orbiter A (and not VO2 as mention
by spance.com) because of the light curve
