  1. It did, before the Canister Rotation Facility (CRF) was constructed in 1993. Before that the cranes in the VAB was used to rotate the canister to and from vertical. When the CRF went online in 1993, these operations happened there. The payload processing still occurred in the appropriate facilities in the KSC Industrial Area. The CRF now serves as the Orion MPCV Launch Abort System Facility (LASF) where the LAS is checked out and attached to Orion.
  2. Thanks for those images. Here's a link to my Ku band references on Dropbox: https://www.dropbox.com/sh/i25uzftliwsthqg/AADGTFJdS-Qtrj1nUpc-YFQUa?dl=0
  3. Hey, niart17, if you're still working on the Ku band antenna, I think I got something that approaches the real thing in the area of the dish-to-bracket interface. I've attached two screenshots of what I currently have. Could you maybe share similar views of your model? You're using SolidWorks right? If I know it right, it has a way to generate multi-view 2D schematics of a 3D object.
  4. niart17, thank you for getting back to me. There's no hurry, it can wait until you get everything squared away. And as for as the that particular area, it looks to be a simple squared shape. Here's a link to a photo of the "back side" of the entire assembly: https://www.dropbox.com/s/xdgenaguo0bw0cj/jsc2010e057439.jpg?dl=0
  5. I'm interested in your Ku band antenna dish. Could you post a 3-view drawing of it? I'm trying to make my 3D model of the shuttke Ku band antenna (in NASA parlance it was called the "Ku band Deployed Assembly or Ku band DA for short) but I'm having trouble getting the rear dish support structure right, mainly where the white bracket attaches to it. So I think having a 3-view drawing would really help. This document on the NASA Technical Report Server (NTRS) has some good drawings of the feed and feed support structure of the Ku band DA: https://ntrs.nasa.gov/api/citations/198100117

  7. Looks very nice. Just one small thing though: The LOX/LH2 cryo pipes should be a shiny metal grey color. I'm not sure when the cryo pipes got painted in the current colors, but at the time of STS-6, they were bare VJ pipes with no paint applied.
  8. Actually, the tiles you're talking about was first used on STS-2. At that time it was configured as a 6x6 square consisting of only HRSI tiles. The current configuration which is a mix of LRSi and HRSI tiles was first used on STS-41G.
  9. The MPPU is disconnected after the MLP is harddown at the pad so that the pad purge system can be connected to the MLP. Once the MMPU has been disconnected and the pad purge is established, the MPPU is removed from the MLP.
  10. Do you mean the large white box on the corner of Side 2/3? Then that is not a generator. It is a Mobile Portable Purge Unit or MPPU for short. The MPPU has 3 purge lines coming from it that are connected to three ports on Side 2 of the MLP. The 3 lines correspond to forward, mid and aft purge circuits on the orbiter. When on the ground the orbiter is always connected to ground provided purge, either regular air or when flowing cryogens during fuel cell servicing and loading the External Tank, gaseous nitrogen (GN2) to reduce the fire hazard. The only times the orbiter is off purge is during
