It&#x27;s interesting to see some differences between the US-and-everyone-else and Russian part. One that was most striking to me is cabling and piping between modules: on the Russian side, the pipes go through the hatches, which complicates closing the hatches but makes the cables and pipes easier to access&#x2F;repair and makes it easier to install new ones. On the other side, there are no pipes or cables going through hatches.<p>There&#x27;s also a hatch in the deck of Unity that seems to have nothing on the other side (the one labelled Hab). Is it a place where a module will be added?
