Timeline
- 00:00:00 - 00:04:56
The launch of Sputnik in 1957 heralded the beginning of human exploration into outer space, prompting advancements in space technology and leading to the formation of NASA. The 1960s saw significant milestones, including men landing on the moon and extended manned space missions. NASA's Gemini and Apollo programs helped scientists study the effects of long-duration spaceflight on the human body, revealing that gravity changes impact balance, coordination, and lead to ailments like motion sickness. Additionally, astronauts experienced reduced bone density and shifting bodily fluids due to lower gravity, causing vision issues and kidney stones.
