For an entire generation, the idea of humans living in space has been a constant reality. But what if this era is about to come to an end? This week marks a remarkable milestone: 25 years of continuous human presence aboard the International Space Station (ISS). Yet, as we celebrate this achievement, a looming question casts a shadow over the future of space habitation.
On November 2, 2000, Commander Bill Shepherd, alongside cosmonauts Yuri Gidzenko and Sergei Krikalev, became the first crew to dock with the ISS aboard the Soyuz TM-31. This historic moment marked the beginning of an unprecedented chapter in human history. However, the station they entered was far from complete. With only three pressurized modules—Zvezda, Zarya, and the Unity module—the ISS was a mere skeleton of its future self. And this is the part most people miss: the early days were fraught with challenges, from glitchy software to malfunctioning hardware, forcing the crew to improvise in ways that would test even the most seasoned astronauts.
The station’s evolution over the next decade was nothing short of miraculous. By 2011, the ISS had transformed into the sprawling outpost we know today, complete with massive solar arrays, laboratories, and additional modules. Crew sizes expanded from three to six, and eventually seven, with astronauts arriving via Russian Soyuz and SpaceX Crew Dragon spacecraft. Yet, despite these triumphs, the ISS is now facing its twilight years.
But here's where it gets controversial: Elon Musk has called for the ISS to be deorbited by 2027, and NASA plans to follow suit by the end of the decade. Zvezda, the aging module built in the 1980s, is leaking air from its seams, and the station’s systems are well past their prime. In 2024, NASA signed a deal with SpaceX, likely paving the way for a modified Dragon spacecraft to send the ISS to a controlled destruction in the Pacific Ocean.
So, what comes next? NASA’s original vision of commercial stations replacing the ISS has faced repeated delays, and the agency has even downgraded its requirements from permanent crews to month-long visits. Is this a sign that we no longer need humans in space? Companies like Varda have demonstrated that manufacturing in space can thrive without human presence, raising questions about the necessity of continuous human habitation.
Yet, breaking a 25-year-old habit isn’t easy. Humanity has grown accustomed to having someone orbiting Earth every 90 minutes, a symbol of our reach beyond the planet. When the ISS falls, that presence will end—at least for now. Do we truly need humans in space, or is this a sentimental attachment to a bygone era? Let’s raise a glass to 25 years of continuous human presence in space, but also pause to consider: what does the future of space exploration look like without it? Share your thoughts below—this is a conversation worth having.
