ISS node

An ISS node refers to a modular component of the International Space Station (ISS) that serves as a connecting hub. These nodes are cylindrical modules equipped with multiple docking ports, allowing other ISS modules, visiting spacecraft, and external payloads to attach. They play a crucial role in the station's overall structure and functionality, facilitating the movement of crew, equipment, and resources throughout the ISS.

Nodes provide pressurized environments and house vital life support systems, utilities, and scientific research equipment. They also contain internal workstations for astronauts to perform experiments, monitor systems, and conduct repairs. The number and configuration of nodes contribute significantly to the ISS's capacity for expansion and its ability to support a diverse range of activities in orbit.
