Greenwich Time and Suspended Animation for Space Travel
Kelly shares that in space travel, they use Greenwich time to accommodate the Moscow subway schedule. He also talks about the possibility of suspended animation for space travel to planets like Jupiter or Saturn.
Physical and Psychological Effects of Being in Space
According to Kelly, there are no physical symptoms of being in space for a long time, but there might be some mental or residual effects. He explains that astronauts cannot hold their breath in space without a spacesuit due to the absence of atmospheric pressure. Kelly also talks about the challenges of studying the physical effects of space on the body, such as bone and muscle loss.
Challenges of Living in Space
Kelly mentions the challenges of living in space, such as floating organs and fluids. He explains that they have grown flowers and lettuce on the International Space Station and plan to grow more complex plants. In terms of oxygen supply, they use a process called electrolysis to create oxygen molecules from water.
Exciting Science Experiments Conducted in Space
Kelly shares two exciting science experiments conducted in space, including one with rodents. He talks about the positive psychological effects of growing plants and working with rodents.
Readjusting to Life on Earth After Space Travel
Kelly discusses the difficulty of readjusting to life on Earth after being in space and how astronauts cope with this. He ends by expressing a desire to go back to space someday.
Conclusion
In conclusion, former NASA astronaut Scott Kelly has shared valuable insights on various topics related to space travel, including the challenges of living in space and exciting science experiments conducted in space. His experiences shed light on the physical and psychological effects of being in space and the importance of studying them for future space travel.
