Named after the most famous love of Aphrodite in the Greek mythology, the X-23A is a simple shuttle system available for a moderate cost.

Just like Eos the objective was to realize a new Shuttle but still with less parts, a lower cost and more important, able to go, land on and come back from the Mun or Minmus. Adonis itself is more than capable of it with a delta-V of 3000 m/s available onboard. The first stage is powered by a Mainsail and a pair of Thud (these ones acting as powerful vernier engines) and got enough power to accelerate the whole system to a speed of 1500 m/s around an altitude of 30 km before running out of propellant.
Once separated the second stage with its Swivel will offer just around 1800 m/s. It will ensure the circularization and a good part of the trans-munar injection.
A Mk1 cabin is located inside the fuselage, which means that you will have to disembark your passenger one by one passing by the cockpit. The X-23A was conceived as a tourist transport craft, so the option to go out of it was not retained.

During its inaugural flight it showed to be pretty easy to control in any situation. The re-entry is smooth and the X-23A will keep its angle without having to interfere. Then even if its lifting surface is pretty low, it can still glide pretty well as I was able to fly it on a distance of about 90 km once at an altitude of 27000 m (so a L/D ratio still inferior to the Space Shuttle Orbiter once in final).

When about to land just keep enough speed to ensure a nice flare. Adonis will stall only around 60-65 m/s so you can easily take your time to make a stable and good approach. In case of a touch far from the threshold a braking chute is available.

A stock spaceplane called Sleg X-23A Adonis. Built with 80 of the finest parts, its root part is Mark2Cockpit.

Built in the VAB in KSP version 1.2.2.

Approaching and enjoying the Target.

And if your head explodes with dark forebodings too… I’ll see you on the dark side of the Mun…
