I think that this question should be closed: Is streamline body shape essential for propagation in the vacuum of space?
As it seems to be a duplicate of this: Are there enough stray gasses in space to justify streamlining a probe?
It seems to me that the consensus is that the older one is better, but we'll see how this answer gets voted.
I think your question should be closed as a duplicate of the older one and no merge should occur. This will leave the Q&A at both places intact, and it will guide anyone who finds your question first to the other question for additional answers. ...
