I didn’t know where else to put this.
I got my weekly news letter, with links to the various questions. The new Cecil answer link is broken. No, wait, that won’t help, its the broken link. Darn.
I went to the front page and it has a different question… Now what? I want to know the end of the answer…
Cecil replies:
The rocks were found on earth, Kent, so they’re meteorites,
not meteors. (Meteors are space rocks that fry in the
atmosphere; meteorites are the remnants that make it all the

Scientists think the martian meteorites came from Mars
because–I realize the nontechnical mind won’t find this
entirely persuasive–they couldn’t plausibly have come from
anywhere else.
The Martian meteorites–34 have been identified to date–are
collectively known as the SNC (pronounced “snick”) group.
The letters stand for three related categories of
geologically unusual meteorite: shergottites, the prototype
of which fell in 1865 near the town of Shergotty in India;
nakhlites, named for a rock that dropped on Nakhla, Egypt,
in 1911; and chassignites, so called because of the specimen
thatlanded in Chassigny, France, in 1815.
For years it was assumed that the SNC meteorites were hunks
of asteroid like pretty much every other space rock. Then in
1979 . . .
sigh…
The Joke-A-Day server sent the mailing 24 hours earlier than it was supposed to.
Our apologies.
We cannot put the new column on the site until after midnight. You’ll just need to sit tight a little bit.
