Splashdown and Post-Space Reconditioning

Splashdown and Post-Space Reconditioning: Recently, Group Captain Shubhanshu Shukla of the Indian Air Force safely returned to Earth after an 18-day mission aboard the International Space Station (ISS) as part of Axiom-4. He completed 288 orbits before safely splashing down in the Pacific Ocean with his crewmates aboard SpaceX’s Dragon spacecraft ‘Grace’.

• About Splashdown : Term used to describe the landing of a spacecraft in water, usually in the ocean, after it returns to Earth from space.

o Enhanced Safety and Simplicity: Spacecraft re-enter Earth at extremely high speeds (over 27,000 km/h).

- Landing in water offers a softer impact than solid ground, as the ocean acts as a cushion, helping to protect both the crew and onboard equipment during the high-speed descent.

• About Post-Space Reconditioning : After spaceflight, astronauts follow a personalised recovery plan to restore balance, spatial orientation, and physical strength affected by microgravity.

o In space, the brain adapts by ignoring gravity signals, which disrupts balance on return, causing motion sickness, spinal discomfort, and muscle weakness.

o It involves physical, medical, nutritional, and psychological support to help astronauts readjust to Earth's gravity.

o NASA Data on Post-Space Health : Over 90% of astronauts face health issues post-mission, with 50% reporting disc herniation, muscle strain, fatigue, and balance problems.
