Of course you do, but does it matter? What did the picture tell us?

Bias? You mean a tendency to believe without evidence? Yup, it happens to
all of us, we should fight it every day. I try, and I don't think I'm
necessarily any better than anyone else.
And HOW does thinking that way make you happier? Do you want to find out
about Mars and stuff, or do you want to point fingers? Where I come from,
OU means Ohio University, but I'm guessing, just a hunch, I may be right or
wrong, that you mean Oxford. It's hard enough keeping our furlongs from
getting mixed up with with our versts without confusing acronyms to spin our
heads. Why can't everyone screech plain, simple, unencumbered or ornamented
English, fer Chrissake? If it was good enough for Confucius, it's good
enough for ME!!!
You know, it's almost like some people WANT to believe that the cameras
didn't work, and SOME people want to believe that they did. Unfortunately,
we have the evidence of our own eyes to help us, but we know that's
misleading, so we try to make sense with what we have. Which may be
information. Or noise. We might be seeing Mars, but I can get better
pictures than that by closing my eyes and pressing my thumbs against my
forehead. So, what did Mars 3 tell us about landing on Mars and taking
pictures and beaming them back to Earth? It's hard. Well, we shoulda known
THAT before we sent our robots. Better luck next time. Try harder. Get
lucky. Be smart. And careful. And we didn't need Beagle for that, did we?
I hope it turns out that the odd Brit Beagles are good and it's only the
even ones that are jinxed (or better yet, only the even prime ones), but
Ad astra, every one!
