    Is there a Thor-Agena model out there at all? I wanted to modify one for the Corona reconnaissance satellite, but I can't seem to find one even though I remember seeing it before. (It'd be even better to find the Corona version itself, but alas, no one has tackled this historic craft--or any other spy satellite, for that matter...) :???:

    Nearly a month, and not a single lead. With all the paper spacecraft out there, and not ONE SINGLE designer has ever drawn a spy satellite? Not to complain, it's just really shocking. I always spent nights when I was a child looking up at the sky and wondering if anyone was watching me. We have NASCAR fans, Star Trek fans, ancient siege weapon fans, even rocket and spacecraft fans, but no spy satellite aficionados?
    I must be the only one. :oops:

    Well, I have an Atlas Agena-D model from the old Precision Paper Space Models I'd be happy to share, but I'm not sure if that's the one you want... didnt find a Thor in my collection. :cry:

    Yeah, the Atlas-Agena seems to be available (well, it was, before Precision disappeared, anyway) but I can't find a Thor. Heck, I'd be happy with just the Agena stage, if it's out there. I'd like to do the Corona satellite at least, and I'll need the Agena. If you've got it, I'd be very glad for you to post it. (Plus I don't have the Atlas-Agena yet...) :grin:

    You never can tell.
    I happen to know one of only three people (in this country, that he knows of) who collects counterfeit paper money and counterfeit metal coins, from the middle ages up to today! Good luck on your hunting

    I love spy satellites! ... my dad is a "rocket scientist" at Vandenberg AFB. He did a lot of work on the Corona etc. :)

    Though I don't know a lot of details seeing that most of his work has/was classified.

    If you can come up with some 3-view drawings or pictures I could probably make up a basic model. Im new to designing, but getting better ;)

    This model can be assembled with rubber cement, white paper glue, or a combination of the two. White paper glue sets faster than rubber cement, but can wrinkle paper. Rubber cement takes longer to set, but the result is usually stain and wrinkle-free. In the following instructions, the term "cement" is used whenever rubber cement is thought to be the preferred method. The term "glue" means that white paper glue should be used.


    1. Cut out Atlas body and Atlas forward bulkhead mount (Page 1). Trace bulkhead mount outline on body underfold section on opposite side of page with pencil. Cement adapter mount to opposite side of gray area, to what will become the inside of the body tube.

    2. Roll Atlas body into a double-layered tube without cementing, then apply rubber cement sparingly with toothpick or small strip of paper at seam only. Use pen or dowel rod inside tube to assist. Clean excess glue with tissue paper. Finish by gluing loose underfold sections at each end
    of the body tube. Use toothpick or small strip of paper to insert glue.

    3. Cut out Atlas Forward and Aft bulkheads (Page 2) and cement to a single layer of cardstock. When dry, cut out Forward Bulkhead and insert into top of Atlas body against Atlas forward bulkhead mount. Trim or sand the bulkhead slightly to get a good fit, if necessary. Apply glue to top of bulkhead once in place. Cut out Atlas Aft bulkhead and glue into place at base of stage against triangular attach tabs, lining up engine fairing base with white engine fairing outlines on side of stage.

    4. Cut out Atlas Main Tank Cylinder/Tapered Section Adapter (Page 2). Roll and cement to inside top of Atlas main tank body tube, allowing feathered half of adapter to extend from tube.

    5. Cut out Atlas Main Tank Tapered Section (Page 2). Roll and cement into a double-layered conic section as in Step 1. When dry, attach to top of Atlas Main Tank Cylinder by carefully aligning tube seams and cementing to the Adapter.

    6. Cut out Atlas Tapered Section Upper Adapter (Page 2). Roll and cement to inside top of Tapered Section, allowing feathered portion to extend from tube.

    7. Cut out long and short instrumentation pods (page 3). Fold and cement/glue into long rectangular channels topped by tapered triangulalar transition sections. Cement into place on opposite sides of Atlas main tank at positions shown. Center the long pod on the Atlas body seam. The bottom of each pod should be at the top of the "ribbed" booster skirt (second line from the missile base). Press the pods firmly against the side of the tank, then press the tapered triangular transition section of each pod into place.

    8. Cut out two booster skirt fairings (page 3). Fold in tabs on each side of fairing. Roll fairing slightly until it assumes a tapered cylindrical shape. Test fit fairing by inserting its top, up to the top line on the fairing, into open base of instrumentation pod and by aligning its base with the Aft Bulkhead. Carefully cement/glue both fairings into place, being sure to center the fairing top and bottom.

    9. Cut out LOX pipe (Page 4). Roll pipe into tight cylinder and cement. Cement LOX pipe to side of Atlas main tank on black line, seam side inward. LOX pipe carried liquid oxygen around fuel tank from the upper LOX tank during fueling on pad and in flight.

    10. Cut out two vernier fairings (Page 4). Fold and glue into tapered triangular shape. Attach to opposite sides of Atlas main tank just above booster fairing (second line up from base of missile). The small 1000 pound thrust, 45 degree angle vernier motors were mounted on these fairings.

    11. Cut out Rocketdyne LR105-5 sustainer engine (page 4). Roll into truncated cone, underfolding inner layer so "B" lines up with "A". Cement underfold end at bottom of thrust chamber. Cut upper adapter strips and fold inward. Glue engine to center of aft bulkhead. The sustainer engine stayed attached to the Atlas body during the flight.

    12. Cut out two Rocketdyne LR89-5 booster engines (page 4). Assemble using sustainer engine procedure. Attach engines to outer positions of aft bulkhead. The booster engines and booster skirt fell away from Atlas after a little more than two minutes of flight.


    13. Cut out tapered Atlas/Agena-D Interstage Adapter (Page 5). Roll, cement, then cement to Atlas Tapered Section Upper Adapter at top of tapered Atlas tank section.

    14. Cut out Atlas/Agena-D Interstage Upper (Cylinder) section (Page 5). Roll, cement, then cement to portion of Atlas Tapered Section Upper Adapter that extends from top of tapered Interstage Adapter. Align Interstage seam with Atlas seam.


    15. Cut out Atlas Agena-D Upper Body (Page 5). Roll and cement into a double-layered cylinder as in Step 1.

    16. Cut out Agena-D Lower Body (Page 5). Roll and test fit into bottom of Agena-D Upper Body. When fit is snug, cement Lower Body into a cylinder, then cement top of Lower Body into bottom (black striped portion) of Upper Body.

    17. Cut out Agena -D base (Page 5) and cement to card stock. Cut out again and glue to base of Agena-D Lower Body.

    18. Cut out Agena -D Nose Cone (Page 5). Roll into cone, then sparingly apply cement to underfold section at seam and at base.

    19. Attach Nose Cone to top of Agena-D by applying cement to attach strips. Align Nose seam with Agena body seam.

    20. Cut out Agena-D Nose Cone Cylinder Overwrap (Page 5). Wrap around "NC" part of Upper Agena-D body, aligning seams, and cement in place.

    21. Cut out Agena-D Nose Cone Top (Page 5) and cement or glue to top of nose cone.

    22. Cut out Bell engine Nozzle (Page 5). Roll into cone and cement. When dry, glue to center of Agena-D base.

    23. When Atlas and Agena are both dry, test fit Agena to top of Atlas Interstage. If necessary, trim interior adapter slightly with scissors to allow for a tight fit. This is meant to be a friction fit.
    Do not glue if you would like to be able to remove Agena later.

    24. Atlas Agena-D is ready to launch!

    Now I'm wasting my time looking for ANY pictures of recon satellites(theoretical, of course... no one really knows what they look like). Most sources say that the KH-11 is similar to the Hubble in shape and size. One very famous photo exists of what may be a Lacrosse radar satellite. Anyone else have diagrams, pictures, artist's concepts, etc?

    Thanks! Between that and the Agena, maybe I can cobble something together for the Corona. :grin:

    Thanks from me as well - I've been looking for a Thor to go with my Blue Streak for a while (the two rockets are on display at the National Space Centre in Leicester, which I visit with my students every year.)

    Thor-Able released


    I have released the thor-able launcher of pioneer 1

    Thanks to Eric Truac for his corporation on this model.

    I will love to do an agena version later.

    Best Regards

    I think the page six from the Atlas Agena D can be had using the page six from the Mercury Atlas 6; the relevant part seems to be only the base, as far as I can tell. Here is the sixed page.
    Hope this helps.

    Agena version


    Thanks about the ideas. My own idea is to make an Agena-A version as an original design of my own.

    Best Regards
