Originally conceived in the 1980s, it was intended to be a more advanced, modular orbital station with improved life-support, scientific capability, and long-duration habitation. Although Mir-2 itself was never completed as a standalone station, many of its planned modules—especially the Zvezda service module—were later incorporated into the International Space Station (ISS), becoming core elements of the ISS’s Russian Orbital Segment.
