  1. The thing is that Saturn IB is buffed (with the dry mass being very far below what an appropriately scaled Saturn IB should be), it's just that it still is anemic despite this.
  2. If that is the case, then the enforcement is either spotty, or has been slowly chipped away by requests. For instance take LMSC-A989142 Volume I and II under NAS8-26362 (NTRS 19740078599, 19730024039). The later is freely available on the modern day NTRS with the designation of Contractor Report (CR), and the former is only found on the Wayback machine, meaning that it was available for download on NTRS pre 2012. This second section has been confirmed to be the case for some time with the report that you were able to make public (19630045066) having long been on the NTRS database classified as Restricted, Limited Distribution, or Classified, as seen in this lovely list of NTRS numbers and titles produced in October of 2017 via FOIA https://documents.theblackvault.com/documents/nasa/NASA-NTRS-Classified-1980.pdf, and most of the documents that I've been finding have been salvaged NTRS numbers from that list.
  3. An incomplete set of the McDonnell Douglas Space Shuttle Phase B System Study detailing the high cross-range delta wing orbiter (Model 050B) and high cross-range booster (Model 256-20). Please note that some of these are very large and can take some time to load (especially with slower internet speeds).
  4. The widebody SLA is in the game. Search for Sarnus-SIVB-BLAM Lunar Adapter Base for mounting plate and Sarnus-SIVB-SLAM Lander Adapter Segment for the panels (note that there are two bases, one in 6.25 and one for 4.25 as the panels can be switched for either size).
  5. Amusing how this is referenced to be a "predecessor" RAM (research and applications module i.e. shuttle spacelab) in the one congressional report where this is found. Unfortunately the RAM papers available online have no information about this.
  6. Not the solar panels themselves, but the 4 pegs that they lock into that are places around the panel (best seen on the fifth image).
  7. Would it be possible to have a switch to remove the solar attachment points, because some of the Orion proposals used basically the same service module with different solar and RCS arrangements?
  8. What it says on the tin: a widebody Agena. Transtage and Agena have nothing in common (and shuttle Transtage was one of the upper sages considered)
  9. These rockets have an ascent profile that one would most often use in stock where the first stage sends the vehicle on a suborbital trajectory followed by a cost to apogee and the subsequent solid stages circularize the orbit by firing sequentially at apogee (or slightly before, the maneuver node for the circularization burn that you should have made will tell you exactly). BDB solids have a action to prematurely shut down the engine, so that you can more accurately choose an orbit.
  10. Are you cloning the 1.11 repository, because that is where the lrv (and some other parts) live at this moment.
  11. The user was asking about Direct ascent Apollo (of which there were several and some could fit on C-5), not C-8 or the Nova direct ascent vehicles. I’ve believe I remember hearing Cobalt mention that he would be open to (or at least entertained the possibility of) making a direct ascent lander that one would launch using an uprated Saturn V, but that doesn’t mean it’s on the cards as I don’t speak for the BDB team.
  12. Cobalt occasionally streams his work on parts for BDB in various states of completion that have various levels of work on them. He’ll link the stream in this topic when he is streaming.
