Tiny Titan II

The failure of the original Tiny Titan to return home from a Mun or Minmus mission, led to the creation of the Mun Rescue craft. With this it was possible to recover the stranded crews, yes plural. Of course this triumph demanded it was time to move forward with the space program. The next phase was the design of the highly successful Tiny Titan II. 

Tiny Titan II
This craft was more than capable of reaching Mun or Minmus and returning the crew safely home. Following is a record of one of its many missions to Mun. The first screenshot shows the ship in orbit with Kerbol and Mun visible in the picture. Note the ejected and not seen lift stage propelled the rocket to 50,000 m. Its Mainsail engines probably could have been exchanged for Skipper engines. Orbit was completed and circularized at 80 km using the orbitor stage.

The orbitor stage also served as transfer stage. The Skipper engine worked its wonders even though a smaller engine might have been a better choice.

Burning For Mun

Kerbol rise over Mun as the Tiny Titan II circularizes. The transfer stage breathes its last at the beginning of the landing phase. Often I eject it with a small amount of fuel to keep landing a little less hectic.

Circularizing

Tiny Titan II On Mun

Tiny Titan II lifts off Mun and heads for orbit.

Munar Ascent

The burn for home. I imagine all of KSP cheered when they realized the crew had the fuel to make it.

Homeward Bound

Glowing red during reentry. It looks more spectacular than normal because Jeb forgot to raise the landing struts. Yeah, I always blame him when I forget something on the to do list.

Reentry

As the ship gets closer it begins to glow white. You can see KSP below.

Glowing

That's no comet. A side shot of the white glow.

And the journey comes safely to an end as the chute fills with air. The last of the fuel is used in landing.

Back At The Space Center

Below for the record is the Tiny Titan II building specs:

Lift Stage
The outer ring is 8 Mainsail engines, each with a Rockomax X200-32 and Rockomax X200-16 fuel tanks. They utilize asparagus staging which drops two assemblies at a time. Each assembly is mounted on a Structural Pylon for extra clearance and a TT-70 radial decoupler. Everything is well strutted. The inner engine that also fires at launch is a Mainsail on a Rockomax X200-32 fuel tank.

Orbit / Transfer / Circularization Stage
A Rockomax Brand Decoupler ejects the Lift stage before firing the Rockomax Skipper engine mounted on 3 Rockomax X200-16 tanks. Stabilization is helped with 4 AV-R8 winglets.

Lander / Return Stage
First a Rockomax Brand Decoupler drops the Orbitor Stage. This stage is built around a Rockomax X200-16 and Rockomax X200-8 fuel tank. To the tanks are added 6 Rockomax 24-77 Engines, 6 LT-1 Landing Struts, 6 Illuminator Mk1 lights, 3 Z-400 Rechargeable batteries, ladder rings, a FL-R1 RCS Fuel Tank, and 4 RV-105 RCS Thruster Blocks.

Rentry Stage
Starting with a Rockomax Brand Decoupler. This is only used when there is not enough fuel to land with the Return Stage or when landing in water. The rest of the stage is a Mk1-2 Command Pod, 3 OX-4W 2x3 Photovoltaic Panels, an Inline Advanced Stabilizer, and a Mk16-XL Parachute.
