On August 25, 2012, the Voyager 1 spacecraft achieved a historic milestone by becoming the first human-made object to enter interstellar space. Voyager 1 is a space probe launched by NASA on September 5, 1977, with the primary mission of exploring the outer planets of our solar system.
After decades of travel, Voyager 1 passed beyond the heliosphere, the region dominated by the Sun's influence, and entered interstellar space—a region between the stars where the influence of the Sun's solar wind gives way to the cosmic environment of the Milky Way galaxy.
This achievement marked a significant moment in space exploration, as Voyager 1 provided scientists with valuable data about the boundary between our solar system and the wider universe. The spacecraft continues to transmit data back to Earth, even though it is billions of miles away from us.
Voyager 1's journey has been an incredible feat of engineering and scientific discovery, and its longevity and contributions have made it one of the most iconic space missions in history.
