スプートニク1号は、ソビエト連邦が1957年10月4日に打ち上げた世界初の人工衛星で、重量は83.6kgでした。コンスタンチン・ツィオルコフスキーの生誕100年と国際地球観測年に合わせて打ち上げられました。科学技術的に大きな成果となっただけでなく、スプートニク・ショックを引き起こし、米ソの宇宙開発競争が開始されるなど、冷戦期の政治状況にも影響を与えました。

Sputnik 1 was the first artificial Earth satellite and the Soviet Union launched it into an elliptical low Earth orbit on October 4, 1957. It orbited for three weeks before its batteries died and then orbited silently for two months before it fell back into the atmosphere. The satellite’s unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments.
