Space travel is the dream of many, but few truly understand the powerful experiences astronauts face during a mission. Astronaut Chris Hadfield, a veteran of three space missions, gives an insightful account of what it's like when a spacecraft launches and lands.
Launch: a symphony of forces
When the spacecraft launches, the astronauts experience a sudden increase in G-forces. This enormous pressure feels like a heavy weight pressing on the chest, making it difficult to breathe. Hadfield describes the experience as "being pushed into your seat by a giant hand."
Impact on health
Physical stress during launch can affect the astronaut's health. High overload forces can cause temporary visual impairment and even loss of consciousness if not properly managed. Astronauts undergo rigorous training to counter these forces, ensuring they remain conscious and alert during critical moments of ascent.
Landing: controlled crash
The return to Earth is no less dramatic. Hadfield describes the descent as a "controlled fall," where the spacecraft plunges into the atmosphere at high speed, creating intense heat and vibration. The thrust of the opening parachutes and the final impact with the ground can be sharp.
Emotional roller coaster
In addition to the physical challenges, the emotional journey is equally intense. The excitement of the launch, the awe of looking at the Earth from space, the relief and sadness of returning home create a unique combination of emotions. Hadfield notes that many astronauts feel a deep sense of accomplishment and a deep connection to humanity after their missions.
Case in point: Hadfield's return
On one occasion, while returning from the International Space Station (ISS), Hadfield experienced a moment of profound clarity. As the spacecraft descended, he reflected on the fragility of the Earth and the importance of preserving our planet. This emotional impact stays with the astronauts long after they return home.
The experiences of astronauts like Chris Hadfield provide a window into the incredible challenges and rewards of space travel. Understanding the physical and emotional toll of launch and landing highlights the bravery and resilience of those who choose to venture beyond our planet.
