SEARCHING for...

Post #1by **ElChristou** » 18.05.2006, 13:50

Hello guys, got a problem...
I'm unable to find a descent document to model the part in the red circle for this new Pioneer...
If someone know a doc that could help, I'll be very grateful...

PS: the only doc I already have are those shown in the top left corner.

It looks like a block of transparent plastic to me

Do you have any idea what the black box is?

The block of plastic might be high-voltage protection around a connector since a cable seems to be running through it, but that's just a guess.

Strange.

If I'm reading the diagram at
http://history.nasa.gov/SP-4012/vol3/p220.htm
correctly, it's either a sun sensor assembly or attitude thrusters. But it certainly doesn't look like what I'd expect...

No idea unfortunatly; I have no documents explaning exactly this configuration of instruments... all I know is:

First on both side there is some thrusters... (no idea how they look)
Then on one side there is at last 3 instruments and here also I'm stunk...

This site has a bunch of cutaways, especially Chapter 3 and 4:
http://history.nasa.gov/SP-349/contents.htm

This is a link to a paper model, perhaps some useful info:

Tx Buggs, I already met those links; the first one is quite useful but don't help me much on this problem...

May be this will help http://www-pw.physics.uiowa.edu/pioneer/gtt.jpg

Found at this location http://www-pw.physics.uiowa.edu/pioneer/gtt.html

But GGT instrument seems not to be the one you are looking at, if I understand this description http://history.nasa.gov/SP-349/p48.htm

and instruments descriptions http://history.nasa.gov/SP-349/ch4.htm

I contacted the head of the Pioneer project, maybe he can be of some help.

No, the gtt is not situated on the side of the dish...
Those doc at www-pw.physics.uiowa.edu are the same than the one at history.nasa.gov...

Tx anyway Jll

Hello Chris, have you got seen these blueprints?
Engineering blueprints of Pioneer 10 and 11:
http://www.ninfinger.org/~sven/models/vault2006/pioneerbp.zip

and

Diagrams of a Pioneer Outer Planets Orbiter
http://www.ninfinger.org/~sven/models/vault2005/Pioneer%20Outer%20Planets%20Orbiter/index.html
Hope thay be new for your project. :wink:

Bye

Wow, and I though I was resourceful. Nice links Andrea.

Andrea, those links are really great, I love the blueprints (now I must do a revision of my model on several points...)
Now, concerning the sides of the dish...

There is a ton of good docs in the vault pages of this site, have you seen the Vostok ones?

MANY TX again...

You are welcome, Chris.
Yes, I have seen the Vostok links, so you can use them, being your model not yet finished.
I sent you something else by email, regarding another project, check it please. :wink:

Folks, have a look at this:

Apparently (it's my interpretation of this pict) the "message" is here turned facing the "inside" of the probe (what I find quite strange indeed), but I'm wondering if it also on the other side...

If someone know more about this, please help! :wink:

If not, what do you think guys? both side or not?

My guess would be for protection from erosion by inter-planetary/inter-stellar dust particles and gas.

[EDIT: or perhaps not: http://www.daviddarling.info/encyclopedia/I/iseros.html ]

buggs_moran · Post #18by **buggs_moran** » 02.06.2006, 20:08

I would agree. Especially around the Jovians. I imagine micrometeorite impacts would get quite high. As a matter of fact, I am suprised they didn't conceal the plaque entirely.

Guys:

Don't know if this will help, but a full-scale duplicate/mockup of Pioneer is on display at the Smithsonian Air and space Museum in Washington, DC. Here is a photo of it:

I can't see the plaque but I think there is one there. I take my students to the museum every autumn. I'd be happy to check it out if you need me to.

Franck,

It would be really great if you can take some shots of some particular points... I still don't have for example anything on the thrusters on both side of the dish...

If you can do that, I will do a pre-release with the actual model, then later after your visit an upgrade...

Is there a similar model of Voyager?
