The Cygnus cargo module mockup represents the pressurized logistics spacecraft used to deliver supplies and scientific equipment to the International Space Station. Built to demonstrate the interior layout of the real cargo vehicle, the mockup shows how food, research payloads, spare parts, and crew provisions are carefully packed and transported to support astronauts living and working in orbit. It helps illustrate the critical role cargo resupply spacecraft play in sustaining long-duration missions in space by ensuring the station continually receives the materials needed for research, maintenance, and daily life.
