I wonder what Bar Sibrel's doing right about now....


If real photos from the surface didn't convince him, why would real
photos from orbit convince him? He's just going to claim they're faked too.


Yep. I was just wondering ;-)

Note the black 'hole' in the top of the Descent Stage:

(zoom in). They look like they might have come close to a 'brew-up'.


Not sure what you mean by that; the hole was always there and ascent
stage ignition was always intended to be "fire-in-the-hole".



There was a thermal and micrometiorite sheild -
http://jeffreyellis.org/tlmp/files/facts/lm_descent.gif. I think it was
also intended to prevent the Ascent Stage thrust from getting into all
the tanks etc on the Descent Stage - no BOOM. Propellant was vented, but
then there was the pressurising gas and any residual oxygen in storage.


I knew about the shield but thought it only covered the tanks, not the
descent engine compartment in the center. The cutaway drawing you linked
doesn't make that clear either. There aren't many pictures of the
descent stage from above, but this one shows an open hole

That one really shows how accurate Pete's landing was.

There's a drawing of the hole in the descent module he

Yeah, but that shows the heat shield as a 'cut-away' - it doesn't show
the extent of the heat shield.

It wasn't just "Pete's landing" - he had a great deal of help from
improved navigation and ranging techniques compared to Apollo 11.

surface (like to Cone Crater) are actually visible, and you can make
out the triangle shape of Surveyors landing pad geometry. Given time
you'll see color and the glint of gold mylar I'm sure........Doc


LRO also got some great shots of the central impact debris mountain in
Tycho crater, showing a large boulder sitting atop it; but no black
monolith yet: http://www.nasa.gov/mission_pages/LR...lro-tycho.html
Now, that really would have been some place to land a LM at; the view
from up there would have been something to see.
It would be fun to know where the boulder came from.

Pat


Shhh... the monolith is hidden inside it. ;-)

That's cool enough I have stored it and set it as the background on my
laptop.

I've always thought that one of the public relations failures of Apollo was
they never went any place interesting enough to compete with the Bonstell
paintings that many of us were familiar with.

What interested me was the apparent darkening of the lunar soil around
the descent stages caused by their landing engine.
