My build of a Muo rocket, a Blue Dog Design Bureau approximation of the Atlas rocket, with a modified Hermes spacecraft which is a BDDB approximation of the Mercury space capsule. The load has been adjusted by removing some of the ablative heat shield while retaining more than enough for re-entry under stock settings.
The mission profile approximates the first two Mercury-Atlas missions with enough fuel to reach a 204x104km orbit with enough battery power for at least three orbits and as many as seven (or more) depending on your electric usage. There are no solar panels or fuel cells so remember to retain enough power to safely re-entry and splashdown.
The ascent profile should stay under a 5 degree angle-of-attack as the rocket can become unstable beyond that, if you want to play it safe you can reduce that to a 4 or even 3 degree angle-of-attack since the rocket is designed to handle a fairly vertical ascent.
The Muo rocket, much like the real life Atlas, is one of the few stage-and-a-half vehicles where a pair of booster rockets draw from the same fuel tank as the primary engine and they should be dropped in the upper-mid atmosphere although my experience so far hasn’t shown a serious issue in riding the boosters all the way to the edge of space.
As long as your initial orbit isn’t too high the separation rockets should put the spent stage in a decaying orbit to avoid any major debris left for future missions. The retro-pack is necessary to de-orbit for re-entry, unlike the previous sub-orbital missions, with no backup in the event of retro-pack failure.
Built in the VAB in KSP version 1.3.1.
