Description: April 12, 2021 - exactly 60 years ago 27-year old cosmonaut Yuri Gagarin became the first man to journey into outer space. At 9:07 a.m. on April 12, 1961, when Gagarin’s Vostok 1 spacecraft lifted off from Baikonur cosmodrome, he uttered the surprisingly informal, immediately iconic exclamation “Поехали!" ("Poyekhali!" - Translation: “Let’s go!”) His flight, a single orbit around the Earth, was uneventful, but the landing ended in near-disaster when the cables joining the Vostok’s descent module and service module failed to separate properly, causing massive shaking as the spacecraft reentered Earth’s atmosphere. Gagarin ejected before landing, parachuting down safely near the Volga River.

Description: The word "TENET" originates from the Sator Square, a word square containing a five-word Latin palindrome that dates back to Ancient Rome. The puzzle is a five-by-five square made up of five 5-letter words written in five lines: SATOR, AREPO, TENET, OPERA, and ROTAS. In every direction the square is rotated, these five words appear both horizontally and vertically - a property that fits the time inversion concept.
