VSO very small orbiter

Is cheap, without high research elements such as R.A.P.I.E.R. engine but still perfect in its role mission task:

safely bring a 3 member crew to/from any Orbital Kerbin station without refuelling.

It reach  100/100 LKO with remaining 1300 ms  of DV enough to reach also any Mün or Minmus station.

Safe. the orbiting ascend is made in only four manoeuvres: take off rotation to 10° ascend angle,  switch to aereospike at 1380 ms, shutdown engine when reached your goal apoapsis, circularise .

Safe on reentry: once you made your preferred deorbit burn just set your VSO to orbit RAD+ with 0 rotation and wait unti il speed slow down, once you regain a correct flying asset you will bless it's almost perfect balanced flying performance: that will allow you to safe land your crew on runaway.

Commands:

1 toggle ramjet

2 toggle aereospike

5 toggle cargo doors, antenna and docking
