First test of the Challenger module in the simulation. The solar panels animation must be implemented yet (later today).
The internal is a derivation and simplification of the Starlab, a reuse of the excellent work of the friend Vittorio (Robitaille_Fan). At the end, I I've decided to give at the internal a more "multipurpose" appearance rather than "logistic/storage", with three sides of the main exagonal module occupied by work stations.
The total mass of the Challenger module is set at 54,915 Kg, so the launch can be accomplished with a Jarvis E launcher, altough it will require a 10 meters fairing, that is unusual for this version of the rocket.

Main solar panels opened.
The total surface, counting the two sides of the panels, is 266 square meters, exactly one half of the Starlab's main arrays. I leave you to calculate the total amount of electric production.
Challenger has autonomous flight capabilities (somebody has called it "a big resupply vehicle"), so it can reach Starlab with no assistance by other spacecrafts. In my view, the auxilliary panels are sufficient for the trip, and the main panels are unfolded once docked, to provide a substantial amount of additional power to the station.
Arguably, this will be the last update for some time. I'm about to embark on a relocation and I have other problems (relationships...) that drains so much time and energy... and joy... but this is another story

Another pill: preview of two possible configurations of Starlab with the expansion module.
The station's layout is not predetermined: the orbinauts will decide to assemble it in the way they want. Or even to mantain the modules separated and place it in different orbits.
Subsequent modules:
- Starchaser laboratory (the one with the canadarm and the Kibo-style experiment pallet)
- Deep Space 2 module. Another water-based shelter identical to the Starlab's one. For supporting an extended crew.

A last snapshot for you: concept of the Deep Space 2 or Shelter 2 module:
Substantially a stand-alone duplicate of the first Shelter module that is built in the main Starlab station, with a docking port and a service module. With facilities for an additional crew. Total pressurized volume: 60 cubic metres (only).
This is a very simple module, with no animations (except for the hatches), no special functions, only one docking port. A rather boring module.
But, with the addition of the water-based radiation shield, that alone is 50 tonnes, the module has a fantastic total weight over 85,000 kg, that is pretty high for the mere 7,000 kg of hypergolic propellant. In result, the delta-V autonomy is low. The challenge for the orbinaut is to manage a rendevouz and docking with Starlab using this heavy and difficult vehicle.
The expected launcher is the Jarvis H.
