Timeline: Evolution of Space Travel (1900–2100)

From the early dreams of rocket pioneers to the bold vision of interstellar exploration, the history of space travel showcases humanity’s relentless curiosity and ambition. In just over a century, we’ve gone from theoretical physics and primitive rockets to Moon landings, reusable spacecraft, and plans for Mars colonies. As private companies and international space agencies race toward the stars, the next frontier is already taking shape—with breakthroughs in AI, propulsion, and off-Earth living. This timeline provides a comprehensive look at the major milestones, innovations, and future visions that define the evolution of space travel from 1900 to 2100.
