October 31, 2000: The Last Day Humanity Shared the Earth
October 31, 2000, marked the last day when all humans were on Earth together, as it was the launch date of the first crew to the International Space Station, symbolizing a new era of international cooperation in space. Since then, the ISS has hosted thousands of experiments and fostered global collaboration, but it is expected to be decommissioned by 2030, with China’s Tiangong space station taking a leading role in human space presence. Challenges like space debris threaten future exploration, but advancements in technology and new commercial and geopolitical efforts are shaping the future of human space exploration.
