Test Engine Contract Question

[SteveD80]

I have a contract to test a Rhino on Mun.  It does not say anything about staging so I believe that it is a right-click->test variety.  I tried to build a rocket that landed a virgin engine on mun, but it keeps exploding on the pad.  So my question is can I test a used engine?

Yes.  You can 'run test' on engines after they have fired.

If your rocket has more than 1 stage by the time it gets to Mun, you can even deactivate the engine, create a new stage above it, move it into the new stage, and then activate the new stage.

Thanks much
