The first spacecraft without man was Sputnik 1.
The Dawn of the Space Age
Sputnik 1 holds a landmark position in history as the first artificial satellite successfully placed into Earth's orbit. Launched by the Soviet Union on October 4, 1957, it marked the beginning of the Space Age and demonstrated the feasibility of sending uncrewed objects beyond Earth's atmosphere. As an uncrewed, or robotic, probe, Sputnik 1 was designed purely to orbit and transmit radio signals, proving that advanced technology could be successfully deployed in space without human passengers.
Key Details of Sputnik 1
Sputnik 1 was launched from the Baikonur Cosmodrome at Tyuratam, a site located approximately 370 km southwest of the small town of Baikonur, in Kazakhstan. At the time of its launch, Kazakhstan was part of the former Soviet Union. Its mission was revolutionary, as it proved that an object could achieve sustained orbit around Earth, laying the groundwork for all future space endeavors, both human and robotic.
