Planned for -way- down the road. Likely 6mo-year. (note the page is created, and has been for a time, but is empty... too far out to even do much concept development on it)

But yes, -eventually- I will be making low-part-count probe/satellite stuff (and there is another part series geared towards manned/unmanned rovers)
