The loss of the ATV (Agena Target Vehicle) for Gemini IX required a new mission, deemed Gemini 9A, and the use of a simplified docking target. The ATDA (Atlas Target Docking Adapter) would serve some of the same functions of the ATV but lacked many of its system including its booster engine. This would still allow the crew of the Gemini 9A to practice rendezvous and docking which were still underdeveloped skills necessary for the future Apollo program to be successful. However as luck would have it one of the ground crew secured one of the lanyards with tape, a no-no in the procedures manual, which meant once the spacecraft’s fairings were to be ejected they were stuck. Gemini 9A confirmed this when Tom Stafford remarked that the ATDA looked like an angry alligator – the mission wasn’t a complete loss and they made two successful rendezvous with the ATDA in the course of the mission.

The Muo Target Docking Adapter (MTDA) is an approximation of the ATDA with a few key differences. The first is there’s no easy way to simulate the stuck fairing so this build is left without the angry alligator – you could tweak things around that might result in a stuck fairing however. The other difference is I have included a small engine and monopropellent fuel supply primarily for the purposes of the MTDA being able to adjust its orbit and send itself to a fiery re-entry once the mission’s completed. It has a very low thrust and about 700 dV so it can technically be used as a booster but not nearly as well as my BTV (Belle Target Vehicle). The MTDA is mostly made from the same parts as my BTV it simply lacks half of the parts.

The Muo lifter handles much like any other Muo lifter build with the stage-and-a-half handling the ascent and circularization. Since the payload is much lighter you can keep the booster fairing on all the way to orbit but nominally you would eject it in the upper mid-atmosphere. The small separation rockets should clear the Muo away from the MTDA and put it in on a sub-orbital trajectory.

Built in the VAB in KSP version 1.3.0.
