Delta II Mars Odyssey scale data needed

Delta II Mars Odyssey scale data needed

Post by Jake Kir » Mon, 09 Apr 2001 16:24:17



Hi all,

I'd like to create a scale model (BT-55 based?) of the Delta II Mars Odyssey launch vehicle and I need a bit of help.
(If you didn't see the launch Saturday you missed a great launch!  The rear facing flight cam images were awesome!)

So I'm looking for the scale data, maybe from the out-of-print issue of Sport Rocketry July/Aug '98?
Supposedly it contains this info.  The NAR site shows that this issue is unavailable (If I understand the website).

I'm willing to send someone a paypal to cover minimal copying/scanning costs if need be.
But I'm hopeful someone can just scan and e-mail me the data.

So (from some rough estimates that I've done) I think this can be scaled with:
- 1 BT-55 for the body.
- 9 BT-5's for the solid boosters.
- and a few BMS nose cones,
 - 1 BMS shape #9 exact dimensions to be determined.
 - 9 BMS shape #1 ditto.

As for the mission decals, I've found them all, but for the triangular Boeing star field.
It can been see at:
http://www-pao.ksc.nasa.gov/kscpao/captions/2001/feb/01pp0460.htm

What exactly is the triangle supposed to be?
Can anyone point me to a source for the triangle (and explain it?)
It looks like at launch time the Mars Odyssey Boeing triangle contained the number 254? or 294?
(and the total number of stars was partially covered with "rocket-tape"?)

I also noticed that the mission decal page that Boeing put up looks like it was done by some marketing folks
in advance, as it's not quite "right", compare the two:
http://www.boeing.com/defense-space/space/delta/delta2/mars_odyssey/b...
http://mars.jpl.nasa.gov/odyssey/mission/images/launch.jpg

If your interested in high quality still photos of Mars Odyssey assembly this was cool:
http://www-pao.ksc.nasa.gov/kscpao/captions/subjects/marsodyssey.htm

If you interested in Delta II multimedia "rocket n'roll" see this as it's totally neat! (warning large!):
http://www.boeing.com/defense-space/space/delta/delta2/mars_odyssey/m...

...it looks like it might contain actual Mars Odyssey launch footage, but it also mentions "stardust" and contains other launch
footage, so maybe was done by the same folks who did the decal page?  (but who cares as it's still totally neat!)

An 8 1/2" x 11" version of my Sport Rocketry drawing appears in the current
edition of "Rockets of the World" (the earlier editions had a a GPS launch on
an earlier version)  Follow the link to Saturn Press in my sig for ordering
information.

I'll take Visa/Mastercard to cover the book, which is $35 + 10% shipping (20%

Thank Pete,
But would you consider sending me just the Delta II (9725 data if you've got it) for a small minimal fee?  (maybe this is a new
economy business op? pick a model, download data for $2-$3 bucks... but maybe that doesn't work with minimum purchase requirements
(then maybe you should look into paypal? - no overhead.)).

- Pete, if you recall, I just purchased your "Scale Bash" book and 3 posters for $30 plus S&H... and they're great, thanks... it was
money well spent.  I'm sure the 1st graders will love them.   (I may even turn you're mailing tube into a rocket!)
But I'm trying to save some cash right now and am not interested in purchasing ROTW at this point in time.
- This is for a 1st grader demo launch in southern New Hampshire... so I'm building a something old and something new (Redstone and
Mars Odyssey Delta II).  Wanna contribute Delta II 9725 scale data?

So if not you, hopefully someone else has the scale data or one of the nearby libraries has Sport Rocketry July/Aug '98, or I'll
attempt scaling it myself from the "Delta II Payload Planners Guide" available at:
http://www.boeing.com/defense-space/space/delta/delta2/guide/index.htm
(but I've never done something like this and would love your data as a "sanity check").

(and a FYI to anyone else that helps out... I'll post the BMS nose cone style/dimensions for a BT-55 based model if I get everyting
together in time to actually do it.).

Pete, you didn't address the other question in my post... (maybe they're Boeing questions...).
- Can anyone point me to a source for the "triangle" marking (and explain it?).
It looks like at launch time the Mars Odyssey Boeing triangle contained the number 254? or 294?.

Thanks again Pete for all you've done for model rocketry.
I apologize for wanting to be so cheap, but I have and do support you, and right now I need to set some limits on my spending.

Jake,
The tirangle has been the Delta insignia from very early on. The numbers
in the triangle are the mission number (I think).  From the photo link I
count 27 stars in the triangle and 25 on the outside.  It shuldn't be
too hard to get the dimensions from that link..you know the diameter of
the real Delta 2 and that's an exceptionally clear photo.  What else do
you want to know about it?

Thanks Kevin,
I count:
- 27 stars inside (same as you do)

- but only 22-23 stars outside the triangle (you got 25!)
(I  wanted to get the number correct.  In the final launch photo:
http://mars.jpl.nasa.gov/odyssey/mission/images/launch.jpg the count looks like 22? but could easily be 23).

- the number within the triangle.  what is it?  254? or 294?  (my guess is launch # also, but I really wanted to know exactly if I'm
going to show a scale model of the Delta II Mars Odyssey to a bunch of curious 1st graders!  (they're smart little boogers!).  But
then again if nobody else can really see it, maybe I'll just make it up! ;-)

I also was curious about the history of the Boeing triangle on the Delta II.
(this is probably a Boeing employee question... I should probably go ask their communications dept.)
- is the triangle only on the Delta II/III/IV? anything else? or do they put it on all rockets?
- why some stars inside and some outside? successful launches/failures?
- maybe they just ran out of physical space and didn't want to scale the triangle?
- is it a mystical rocketeer good luck charm?

FWIW, NAR sells back issues of Sport Rocketry, subject to availability.

From the Delta II launch record:
http://www.boeing.com/defense-space/space/delta/record.htm
it shows that the Mars Odyssey was flight # 284.

Yeah I got 13 running up the right hand side from tip to tip.  I suppose
there could be a different number of stars on the other side, but going
with the same number (minus 1 for the star at the apex I counted
already) gives me 12  on the left side.

In the Crash and Burn issue of HPR they have printed the Delta II triangle
with the stars shown. There are 23 outside and 27 inside for a total of 50,
like our flag. I don't know if that is the relevance.

Steve,
What month was the Crash and Burn issue of HPR?

I just asked Boeing media communications....
- the triangle is just a greek "delta" symbol that been used since the
beginning.
- initially they said the number of stars was the number of Delta II rockets of
that series type (9725), but they are going to get back to me on that (maybe
with a nice *.jpg that could be used to create a decal).
note: looking at http://www.boeing.com/defense-space/space/delta/record.htm it
looks like there has been ~100 launches?

I've also been thinking, the only hard part about modeling the 'stars' and
'delta' is that they use the color white, so white ink on clear decal is
needed.  The same would go for the Boeing swoosh logo thingy as it's also white
in color

BTW, I am still looking for the Sport Rocketry July/Aug '98 Delta II scale data
if anybody has it to share.
(none of the local libraries I've checked with carry Sport Rocketry.   The
nar.org site only has a snail mail address (no phone# or e-mail) and it's not
even clear from this http://www.nar.org/backissues.html that a photo copy is
still available (missing a blue square and price?).  I also don't want to
wait... as I'm trying to be ready for http://www.spaceday.com.  Maybe I'll just
end up doing it myself, but I sure appreciate an e-mail containing a scan of the
relevant pages from Sport Rocketry.

Thanks,
Jake

*BUZZZ* I'm sorry, but thank you for playing. See my other post for the

Delta II Mars Odyssey scale data needed

Post by Steve S » Fri, 13 Apr 2001 14:58:53


Fred
You're welcome for playing. I even had my wife count and the answer is still
the same. In the picture, there are 50 stars. 23 on the outside and 27 on
the inside. Because this issue was intended to be published in July 1998, I
doubt that the number of missions flown would have decreased since then. I
don't know the rationale behind displaying 50, and perhaps HPR published an
incorrect picture, but I have scanned it and would be happy to email it to
any doubting Freds. :-)
It is a jpg scanned at 150 dpi. The file size is about 29KB.

Delta II Mars Odyssey scale data needed

Post by Fred Shecte » Fri, 13 Apr 2001 22:38:15


Well, Moose says "the total star count represents the consecutive success
(in a row) record, presently at 47. We were doing fine until Jan 97.".

Since I am now lost in this thread, please re-state the question again
(which Delta were you looking at/counting stars on?). I ASSumed that the
question was on the Mars Odyssey Delta II, but then you mention something
being published in 1998. I'm confused because I thought that the Mars
Odyssey was just launched a few days ago and there could be no photos of
that specific Delta II in 1998.  The number of stars changes for each Delta.

Please help un-confuse me about what exactly we are talking about.
