After missions like Artemis II, astronauts don’t just celebrate—they struggle to readjust to Earth.
Reentry at extreme speeds is intense, but the real shock comes after landing. In microgravity, muscles weaken and balance systems adapt, so back on Earth even standing can feel overwhelming.
Astronauts often feel dizzy, heavy, and unstable, needing immediate medical support and rehabilitation to regain strength and coordination.
In short: returning home is physically harder than it looks—gravity becomes the final challenge.
