This episode explores how humanity's relationship with time transformed the moment we left Earth. From Sputnik's first orbit to Yuri Gagarin's 108-minute spaceflight and Neil Armstrong's moon landing, time shifted from minutes and hours to orbits, countdowns, and light-years. Astronauts aboard the ISS witness 16 sunrises a day, while NASA engineers adapt to Martian time.

As space exploration advanced, the universe itself became a cosmic clock, with starlight serving as ancient memories from millions of years ago. What began as a race between nations is now a race for human survival beyond Earth. In space, time is not just measured — it is chased, stretched, and rewritten.
