On October 4, 1957 the Soviet Union launched Sputnik 1, the world’s first artificial Earth satellite.
Key facts:
- Launch: Baikonur Cosmodrome (then Tyuratam), 4 Oct 1957, about 19:28:34 UTC.
- Satellite: a 58 cm (23 in) diameter polished metal sphere, mass ≈ 83.6 kg (184 lb).
- Signals: it transmitted simple radio “beeps” on 20.005 and 40.002 MHz that could be received by radio operators worldwide.
- Orbit: roughly 96-minute period; it stayed in orbit until burning up on reentry on January 4, 1958.
- Significance: Sputnik 1 inaugurated the Space Age and the U.S.–Soviet Space Race, sparked the “Sputnik crisis” in the West, and led to major changes in science and defense policy (including creation of NASA in 1958).
If you want, I can give more details about the launch vehicle, public reaction, technical specs, or subsequent missions.
