What is the largest structure people have put into space?

Answer 1

The largest structure that humans have put into space is the International Space Station (ISS). The ISS is a modular space station that serves as a microgravity research laboratory where scientific research is conducted in astrobiology, astronomy, meteorology, and other fields. As of my last update, the ISS measures about 109 meters (358 feet) from end to end and has a mass of approximately 420,000 kilograms (around 925,000 pounds). It has been continuously inhabited since November 2000 and is a collaborative project involving multiple space agencies, including NASA, Roscosmos, ESA, JAXA, and CSA.
