I assume this was for STS Commander Rank 1, but I can't tell the difference between the badges.  Looking at the OP, both STS Pilot Rank 1 and STS Commandr Rank 1 have two badges for each, and either I'm blind or I can't tell the difference between them, other than fir left badge for each has gold trim and tie right badge has white trim (the feathering  to each side of the word Challenge in each)

Exactly as @hoioh said, gold star is for commander level, and silver branches are for "modded" category.

The difference is in the colour of the stars for the ranks and the colour of the feathers for mods/stock

Ok, thanks.  So I guess that gold feathers is stock, and white feathers is modded

Gaaah.  Ninja'd

STS-1B completed last night, here are the images and video.  Note that the fuel pod's total weight is about 43 tons.  This due to having to redesign it to fit into the Mk 2.5 shuttle

Alright, now we have a proof of your shuttle's notable cargo capacity to (at least) LKO, and with quite a bit of fuel to spare! Very precise orbit, and a pinpoint landing, so a badge for you:

I can't help but notice though, the fuel pod is quite a tight fit in the cargo bay - I'm curious how much trouble it's going to do in the recovery mission.... :)

Wow, the Octosats look very good :) And very nice usage of action groups to deploy all the stuff on them simultaneously, looking very nice in the video! Very good job building the comm network, and it seems you're getting the hang of the reentry procedures, too - you seem to get closer and closer to KSC every mission!

So, a third badge for you:

Congratulations,

Same shuttle, but will be replacing the wings.

I'll use the docking port at the back to grab hold, and then will probably use eva struts to hold it in place (unless that isn't allowed)

No reason why that would not be allowed. I'm just curious how you'll manage the docking with the very tight cargo bay, that's all ;)

It will be very tight, at least until the docking port at the end grabs hold.

I can't use a docking port on the base of the shuttle because it bleeds through, and would at the very least look very strange to see this round cylinder coming out the bottom.

What I'm concerned about is the reentry and landing.  That configuration won't have a lot of leeway, the jets only help, can't really keep it up.

The fuel pod return is going to be my next mission, on Sunday evening, I think.

Talking about strange looks: the payload is heavy enough that the senior port can't keep it inside the cargo bay, at least not under 1g. On the runway, the cargo hangs out like a horse's... radish.

On my shuttle the CoM shift left me with so little control authority that the landing site was essentially determined by the de-orbit burn. Back to the drawing board!

My big shuttle has its disadvantages, but one advantage I like is that I can place cargo adapters all over the place to control where the CoM is, and TAC Fuel Balancer to help adjust it in flight if needed. It's designed so that the default CoM (fueled but no cargo) is nearly dead center of the cargo bay.

Only if it isn't strutted, which it was.

That's one reason I had a fuel tank in front and in back.  I use the PWBFuelBalancer Rebalanced & Resource Jettisoning which I revived and enhanced.  In one of the shuttle missions above (the one which brought the 43 ton tank up), the balance was off enough that I lost control of the shuttle, but was able to both vent and rebalance it so that I was able to move the CG forward enough to regain control and land the shuttle back at the KSC

I was not happy with TAC Fuel Balancer, which is one reason I revived the PWB Fuel Balancer mod

PWB looks pretty cool, I'll have to check that out. One thing I like about TAC that PWB doesn't seem to have though is the ability to detect stages and act on their tanks as a single group. Like, maybe I want to pump fuel around my mothership but leave my landers alone, without having to zoom in on the lander and lock its tanks and docking port manually.

Interesting, I hadn't thought about that.  Shouldn't be too difficult to detect, it's the UI which will be a vhallenge

The Fuel dump functionality in PWB is brand new, so I'm sure other things will be added.  My goal is to keep it simple, if possible, yet powerful

Well, I use quite a bunch of mods you maintain and personally, I'm very happy with them! So, thank you!

I haven't flown any shuttles in a while, but always do my own fuel balancing manually, it may be interesting to check out PWB to see if it makes flying easier, especially where it concerns off-axis thust, which is always an issue with my shuttles

So, am I the only one who designs the orbiter to be flyable through the atmosphere at any given time without shifting any fuel? 

Guess, that's one the reasons why it takes me a couple of weeks to build a new one :D

I don't touch the fuel except sometimes when landing with an unbalanced cargo, but my booster design is symmetrical so there's that .. :D

Days it takes me, at worst. Usually my shuttles are 1 or 2 day builds

Well, it happens a bit too often that I decide to throw away everything and start over again.

The one I'm building right now is supposed to have ~3500m/s dV when arriving in LKO, so it can reach Eve and Duna (maybe even land on Duna) but I always end up with 4000+m/s when using nuclear engines or 2800 when using LFO engines. I could use the wolfhound to boost the LFO effiency but since the engine bell is really huge, it looks just stupid. Apropos look: it is supposed to be smaller (~cockpit + 8 x the length of the small MK3 tanks)

It is a bit tricky though^^

My Bustard orbiter (the big one) took a few days, but after that the only modifications I've done are attachment point locations, and maybe a few minor tweaks. The Tetrax orbiter only took a couple hours - basically I took a Bustard, cut the cargo bay in half, cut the wings and vertical stabilizer down, reworked the engines, made a few other tweaks, then put the Firetail launch system on it.

Speaking of launch systems, that's where I've spent most of my time. (That x-ray telescope I did for STS-3 also took a while, but that was mostly aesthetic.) The newer Firetail took like a day an a half or so - I've done similar things before, so it was mostly just adapting it to my shuttles. The older Phoenix (Energia-type) ate more hours than I can count, mostly in rebalancing the engine torque for each payload.

I've started working on a Phoenix II system, with asymmetrical main engines. (thanks for the tip, @Alchemist!) Looks promising so far. Load testing with a weighted orbiter mockup shows much smaller torque variance due to CoM shifting over time. I can probably use the same strap-on boosters, I just need to change the mounting angle.

 Nope, I've been doing that as well. 

Watch for a new mod to be released in the next day or so which will make it much easier to load and unload individual resources (ie: fuel) in the Editor from all tanks in a stage, or the entire vessel.  This will make it easier to check the balance with different fuel loads

Sounds interesting.

When you say 'different fuel loads' does it mean 'full' and 'empty' or will we be able to set any fuel load we want? What ever it will be, the stage separation will be very helpful to balance the orbiter while it is strapped to the launch vehicle, so this is going to be great anyway :)
I'm already excited :D

You will be able to adjust each resource type, either for individual stages or the entire vessel

That would be a wonderful thing to have within the RCS Build Aid interface. Not that it wouldn't work just fine externally, but I think the features you propose would be a bit more synergistic in combination with RCSBA.

So I'm working on STS-4, trying to engineer an accident to justify a rescue. It's surprisingly hard to create a semi-controlled explosion that does the damage you want without destroying too much. I think I got it though. The secret is strategically placed Fleas.

@sturmhauke I've used the 'Kaboom' mod for this, it's the perfect solution to create a controllable explosion ;)

Maybe the explosion will be a bit smaller, depending on how many parts you're going to destroy ;)

Oh right, I've heard of that mod. I forgot about it before this though, oh well.
