This is most expensive thing made by humankind ever, costs more than Mukesh Ambani's Antilia, it is...

When you think of the costliest human creations, what comes to mind? Perhaps iconic skyscrapers like the Burj Khalifa, architectural wonders like the Taj Mahal, or cutting-edge machines like a colossal aircraft. But none of these claims the title. Instead, the most expensive man-made structure isn’t even on Earth—it’s orbiting above us. The International Space Station (ISS), a technological masterpiece, holds this distinction with an estimated cost exceeding $100 billion, as recognized by the Guinness World Records.

Guinness World Records describes the ISS as the "most expensive man-made object" due to its astronomical price tag, which some sources place at over $150 billion. But what justifies this hefty investment? The ISS represents an unprecedented collaboration among international space agencies, including NASA, the Canadian Space Agency (CSA), Japan's JAXA, and Russia's Roscosmos. Conceived in the 1980s as NASA's "Freedom" space station, it evolved into a global project when it became clear that a single nation couldn’t handle the scale of such an endeavor. Launched on November 20, 1998, the ISS was envisioned as a versatile hub for research, exploration, and innovation in low-Earth orbit.

Designed with a modular structure, the ISS can adapt to changing needs, allowing for the addition or removal of components. This adaptability supports its roles as a laboratory, observatory, and even a staging area for future missions to the Moon and Mars. Its critical systems include life support, power management, and advanced communication networks. Maintaining this marvel isn’t cheap either—millions are spent each year on repairs and upgrades, making the ISS a continually growing investment in humanity’s exploration of space.
