The smallest shuttle I ever built for now. The objective was to lower the price to less than 40k funds. And the target is reached for Nephthys, with a full operational launching cost of 39 245.

Named after the legendary Egyptian goddess, protector of the departed, the X-39A actually is more a kind of rescue machine. Even if a Mk 1 in-line cockpit is available, a Mk 1 cabin section also is available in the craft, giving her a three seats capability.

The orbiter itself enjoy about 2.3 km/s of impulsion available, plus 1 km/s for the 3rd stage. Enough to visit two stations, or other vessels, on two largely different orbits before returning to the KSC. Or, you can also visit Kerbin’s natural satellites easily with tourists, for the modest cost of just 27300 funds!

This spacecraft was built as some kind of a multi-roles light one, able to serve as an escape vessel from a station, or as a touristic vessel.

About the flight this craft is everything but hard to maneuver. From the launching to the landing Nephthys is pretty easy to control, and answer your inputs pretty well. The best part (to me) being her ability to stay stable during the reenter.

Just one thing has to be looked at: the level of electricity. The X-39A only had 250 units and two small solar panels, so it is always better to keep the upper side of the craft lighted during the transfers (and to evade night maneuverings).

A stock rocket called Sleg X-39A Nephthys. Built with 57 of the finest parts, its root part is Mark2Cockpit.

Built in the VAB in KSP version 1.3.1.
