This was more of a test of the new Jool I Launch Assembly. We attached a small science lab to the top of it that outweighs the lander that we will be proposing to go to Mynmus, and launched it into orbit to see how it performs. Admirably, by the way, and with plenty of fuel left over in the third stage to most likely get us all the way to Mynmus. There is a fourth stage for the actual landing at Mynmus, plus return to Kerbin.
The unit is currently in orbit around Kerbin, and will act as a part of the space station that will eventually be built there.
