ISS Build - Parts Bag 4

This portion of the International Space Station  build gets increasingly interesting, as this is where more of the intricate detail is added: laboratory modules, node sections, Soyuz 'lifeboats',  microwave dish antennas, and myriad other gadgets.

Not knowing much about the ISS, I had to go online to the NASA website to take a crash course and educate myself about this remarkable craft.  Luckily, I found several detailed diagrams identifying the major components, as well as project construction timelines, and many other details.
In the process, I learned a lot and gained quite a bit of respect for the designer of this LEGO model.
