Blender has some ability for texturing. I'll see what I can do

I was thinking in a ISS-like truss with Arrow-like slots, but you can develop any other idea if you don't like it. Six sides, one side for docking/berting to the station, four sides with room for five UCGO slots each.

Ah, now I think I know what you're looking for:thumbup:
I'll get on a new design as soon as I can

Is this more like what you had in mind?

Yes! Something like this.

Docking ports at either end? Where should I put the station attachment point?

One docking port is fine. It wil be docked to the command module only, so, it needs only one.

About the module: I like IMS very much, but the lack of compatibility with graphics clients makes me feel unsure to use it. I was thinking to write a simpler code, but with cool functionality and a interesting idea: making each module separated, so they could work automonously in the case of the station being disassembled or malfunctioning.
I thought about a fuel-celled command module and a solar powered service module. The command module would have limited funcionality (fuel cell for 28 days, refuellable) and the SM could work for a longer time. I can post a diagram later.
The cargo module remains the same in this case.

Okay. I really need to finish that cargo mod anyway...

Here's a bare-bones version of the cargo module; sorry it took so long
Just let me know if you want me to do any tweaking with it.

O don't have blender here. Can you export to 3DS?

Okay, here it is. Sorry that took so long, but I've been completely slammed at work, so when I come home I just fall face down on my bed and don't wake up until 5:30 the next morning

I like it. It would be nice to design something to limit the slots, like bars or any other stuff.
About the docking port: is its size random? It would be useful make some kind of standard: the size of all docking ports could be the same of the DP of the Vanguard.

Here's a concept for a cislunar UCGO transportation system. I can further develop the concept if you are interested.
- Can carry up to 24 UCGO boxes
- Two docking ports
- Electrical systems powered by fuel cells (rechargable via an UCGO box)
- Draco-like thrusters - attitude and orbital operations only: the TLI and TEI would be performed by a tug specially developed for it.
Basic operation: the UTS starts in orbit or docked to the ISS and receives the tug and the boxes. After receiving the boxes, it goes for TLI, LOI and perform rendezvous with the lunar station. It docks (or an URMS grapple it) and transfers the boxes. It goes for TEI and performs EOI via aerocapture, being ready again after refuelling.
Yes, the XR5 can do the task, but inverted reentry is a dangerous procedure and we can't risk the lives of our astronauts just because of cargo...

Hmmm...and the XR-5 doesn't have the delta-v for two launches and two insertions. So you are quite right: no XR-5
I love your idea though
We could make this into a sort of cargo-carrying version of the Dragonfly, with all those super-detailed electric and life-support systems. For the tug, what about using Bruce's Shuttle-D?

The Shuttle-D, empty, has only 4730 m/s of delta-v. We need something like a Centaur upper stage.
The XR5, empty, can even land on the Moon and back to Earth. But I haven't tested it fully loaded.
The detaliled electric systems (at first, I imagined a unmanned vessel) is a cool idea and could be added in a 2.0 version (after I learn how to code it =p). We can finish the 1.0 version with the APU fuel consumption only, like in the XR series.
Expanding the concept a little: the main thrusters can be inside the heat shield, around the second docking port. The HS could open like a flower when not being in an atmosphere to allow the use of the docking port and main thrusters.

If I upload the new Shuttle-DB files you can use them. It has a DV of about 7000 m/s on its own, and it should be able to push some modest sized modules into Lunar orbit. If you feel comfortable doing 2 launches, the module & a LH2 fuel tank could go first, then the Shuttle-DB can launch to catch up with it. Does that sound good?

The Shuttle-DB would be nice for smaller payloads. I'm planning a full capacity of 25mT of UCGO boxes for UTS. If fully loaded, the Centaur-like tug would be needed.

*Doing research and calcularions* - 25mt is too much, we would need a BIG tug (about 2 times the size of the Centaur).
Hmmm... :hmm:
Bruce: how many kg the Shuttle-DB can carry to LLO? Will it carry UCGO boxes? It does a cislunar roundtrip?

The DB has no UCGO cargo capabilities. I can estimate payload pushable for you though.
Straight from my notebook, should give you accurate payload estimates to anywhere in local space. Assuming a direct ascent & rendezvous leaving about 18000 kgof LH2 in the tanks (7000 m/s dry), the DB should be able to deliver max 17 metric tonnes to lunar orbit, but I would reccomend about 16 in order to give you a safety margin.
So should I assemble an early release package for you?
