Space shuttle payloads?

[bh]

Does anyone know where I can find payload bay diagrams for the shuttle?

Regards...bh.

Im not sure if this is exactly what you are after
but this web page has Pictures, Information and even 3D models

http://sspp.gsfc.nasa.gov/

How about this for a payload... and a view

Thanks for these Paul...I've been trawling the net all day looking for payload bay configs...I don't want to get these wrong but I may have to make a 'generic' mission to apply the payload models I have so far.

They really are nice models and need to be added to the project.

Regards...bh.

I will post some 'raw' models and try to get some feedback...maybe the 'Orbiter' guys can help here.

First shuttle with payload bay detail:

This is a tryout for the payload bay models I have at present...so it is fictional.
However...I will try to make some mission specific payload bay configs for these models...I will need some help I think!...the combinations are endless!

For models I have 'Astro2', the 'TSS' and the micro grav with other scientific experiments...on 'Discovery' on this model.

I will do some for 'Endeavour'...at the moment I'm working on STS108.

If I can get these right I will be naming the models as of their mission name...ie, STS104 or whatever.

I hope that made some sense!

You can try out this model here:

Sorry...immenent sprog!

Many regards...bh.

Sorry..not logged in again!!...If anyone has a specific request for a shuttle mission, send me any diagrams, drawings, photos or whatever...and I will do my best.

Regards...bh.

PS...you need to install the textures that come with this model!

Sorry...immenent sprog!

Hey bh, CONGRATULATIONS!!!! You kept that quiet, I hope all goes well for your good lady and yourself. When's it due?

I haven't had chance to download this yet but it's looking good. Giving each 'payload' shuttle model it's mission name is a good idea and I think the best way to go about this!

As for payload bay diagrams on the internet, I've got to admit I've been struggling. The best source of info is probably in books

Thanks TERRIER...bh mark3 due on Saturday (4th) but I reckon on Wednesday (tomorrow) or Thursday!!

[ElPelado]

looks grate.
1)i think i saw a video of a shuttle docking with the iss, and in teh cargo bay i saw many "boxes". you may want to put those "boxes", containing food for example, in your shuttle-iss model.
2)if you do the models with mission names, will they have also their real orbits?? i mean, the ones that those missions made, with their begining and ending date?

[bh]

I won't be writing any sscs for these models...it's not my field, although I may ask for some help on certain models.

There's a lot more detail that needs adding inside the cargo bay...every mission seems to have a different configuration. I will work on this.

Regards...bh.

[Darkmiss]

I like that payload shuttle a lot
It's really starting to bring the model to life now.

And all the best to you and your wife, with the new baby
Hope all goes as well as can be.

[bh]

Thanks Paul...yeah...I think it tends to make sense of the shuttle and what is was (is) for...

I've got a couple of missions on the go at the moment...but you can use this model of 'Discovery' as a proper STS...I will find mission no. Later! I'm a bit of a bag of nerves at the moment!

I will post these up when they're done...Astro2 on board 'Endeavour' and STS108. I will try to add all the 'GAS' (Get Away Specials) and other 'food' boxes. I really have a lot to go on!

Many regards...bh.

[bh]

Probably the last couple of models for a while...two proper missions, STS-67 and STS-108:

And...

The 'Astro 2' observatory...and...STS-108 to the ISS


You can get them off my shuttle page:

These are looking really good bh.

I am however, trying to produce some accurate orbits for these two missions.

I've paid a visit to the 'CelesTrak' NORAD 2-line element orbit data website and have taken a random orbital data line from the middle of each mission as follows;

STS-67:

1 23500U 95007A 95067.91666667 .00001115 00000-0 51364-5 0 202
2 23500 28.4646 41.3584 0012370 353.6551 304.9396 15.72594604 1040

STS-108:

1 26995U 01054A 01346.58333333 .00003361 00000-0 43775-4 0 350
2 26995 51.6394 271.0216 0005353 78.2176 113.1724 15.61964355 731

from this info I have come up with the following ssc, allowing the missions to run as follows;
STS-67 from 2-March-1995 to 18th March 1995
STS-108 from 5-December-2001 to 17th December 2001

Code: Select all

"STS - 67 (2-Mar-95)" "Sol/Earth"

EllipticalOrbit {
      Period          0.0640219
      SemiMajorAxis   ?
      Eccentricity  0.0005353
      Inclination     51.6394
      AscendingNode 271.0216
      ArgOfPericenter  78.2176
    MeanAnomaly 113.1724
   }
      Orientation     [90 0 0 1]
      RotationOffset  -90
      Obliquity       51.6394

   Albedo 0.10
}

Unfortunately I am missing the SemiMajorAxis for both, and I have no idea how to get them. The space shuttle reference pages on NASA's site quote an altitude for mission STS-67 equal to 187nm, while for STS-108 it is equal to 122nm. I do not know what these figures are either.

Also, I suppose if I want to be even more accurate I will need an epoch date too, but I'm not sure about this either

Please can anyone help?

A while ago, I built a spreadsheet utility that automatically converts two-line element sets to Celestia definitions. It's on Selden's site at http://www.lns.cornell.edu/~seb/celestia/hutchison/spreadsheets.html. If you paste the original Celestrak TLEs into the spreadsheet, you'll get the following definitions out:

Code: Select all

    Period  0.06358918      
    SemiMajorAxis  6729.615

You need to insert the appropriate Mesh statement for the model you're using, and correct the automatically generated Radius to something more appropriate for the shuttle. You'll also likely need to make adjustments to the shuttle attitude with an Orientation statement, and probably tweak RotationOffset by adding a multiple of 90 degrees.

The quoted altitudes from NASA are in nautical miles, which convert to kilometres if you multiply by 1.852. Add the radius of the Earth, 6378km, to get a SemiMajorAxis. The figures from this calculation are presumably the average for the entire mission and, not surprisingly, they come out rather differently from the calculations based on the instantaneous period given by your two-line element sets.

Cor!...blimey!

R O C K I N G...

Don't forget to add in my new NASA logo though!

[TERRIER]

Cheers for your help Grant.

Knowing the xyz orientation of the model, I've worked around this, and then adjusted (fudged!) the rotation offset to position each shuttle so that they orbit the Earth 'engine first', and with each underside reasonably parallel to the surface.

Here's my ssc

R O C K I N G...

Yes ROCKING indeed!
I like the new deployed KU band antenna bh, I just couldn't get it right for the life in me!

[bh]

Grant...TERRIER...many thanks for the work you've put in to the orbital data for these models. I will add the sscs to the zips if you don't mind.

Kband antenna by shrox, guess which model it comes from!

ISS module by Jack, guess which model it comes from...I'm becoming a bit of a 3d pirate I'm afraid!

Jack...doh!...forgot about the new Nasa logos again!...I will update the models with this over the weekend...hopefully!

This logo is OK for the 'Discovery' payload model (I think).

I think the ODS is wrong for ISS docking scenarios...I think the extended version was for 'Mir' only...so I will work on these too. Should be correct for STS108.

Many thanks for all your help.

Regards..bh.

Hello Jack...the ISS module was made out of parts for your Salyut 7 model!
