Huh. I stand corrected.

It is. The idea was to keep the command module at the same height as the Standard Lunar Saturn V, but they didn't have the space in the SLA for the SPS's bell, so they had to use a short service module, and place the entire engine with bell in the volume of the standard service module.

The stream is live.

Hey, I haven't added that much to the roadmap at all. I've held off on NLS & ALS in deference to your dislike of SOFI orange tanks.

Yeah, your 'joke' was not funny at all.

The car accident thing was a joke on the part of@CobaltWolf

Ok, getting back to this, the first thing you have to remember is that TIMBERWIND never produced even a full-up prototype - just prototype-of-a-prototype subcomponents (work on fuel elements, composite turbines, ect.) You can get a lot of info on it here, on DTIC. Like most NTR engines, you don't end up with a lot of plumbing or components around the reactor giving it a very simple look. I'd look at the numerous NTR images from the late 1990s and early 2000s as they were often based on TIMBERWIND technologies.

I think that the second image isn't from TIMBERWIND, but from earlier NTR work (hence the Titan IIIM, not a Titan IV. I do have some references at home, but alas I am not there at the moment.

I don't remember what was written about the ETS Titan V with respect to dimensions - but LDC Titan likely means we get the UA-156X SRMs, which translate to 2.5m solids, allowing a full family of Solid Single Sticks from 1.5m to 3.75m (eventually with the AJ-260).

Cobalt, you know me. LDC Titan > Saturn, if only for the novelty.

Oh, that is much better. Without a third stage I can almost send a small probe to Eve on day 1 (NASA would have needed the JPL 6K stage to do the same).

@Jso One issue I have with Vejur is the mass. Right now, the dry mass for Vejur is in excess of that of the Muo-D at burnout. I'd lower that down from the three-and-change tonnes it is now to the one and a half to two ton range. Remember, the real thing would have only massed a tonne or so, and had a mass fraction in the 90% range (balloon tanks for the win). While the Inon stage has a similar mass fraction as Vejur (~.64-.70), it is also only one third of the dry mass. I know that hitting the balance point is hard, but I'm pretty sure that she's not there yet.

Kerbal-ETS Sarnus 1C launch:

For those that want to have prebuilt Sarnus stages, I have the S-I, S-IC, S-IE (ETS), S-II, S-IV, S-IVB for Sarnus 1, and S-IVB for Sarnus II/V.: Zip Linky (personal server). Note, this is the quick and dirty version. Better version will come after more sleep.

Now flying Saturn IIs to orbit:

One vote for VEGA.

Best Saturn Apollo Ever. Now a must download.

Alas, most info on it got pulled in the great NTRS takedown. Given that however, we do have this: http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20000033816.pdf and this:

I'd prefer blue to keep the pattern (of blue for cryo) going.

@CobaltWolf, I know I'm a little late, but I've got this image I had forgotten about:

@Pak Just a side note, the LRBs would have used liquid fuel separation motors instead of solid fuel ones.

The Worm wasn't approved until 1975. Not even ASTP used the Worm.

One thing that might be fun, was something that came out of Shuttle-C work in the mid-late 1980s: A Double Payload Bay Shuttle Derived Vehicle: Source PDF (pages 26 and 28)

Kanaloa!

One of the lifting bodies has a flat back end for Buran style lifters, while the other has an angled back for Shuttle Style lifters.
