On Wednesday, March 19, NASA astronauts Sunita Williams and Butch Wilmore will safely land in the Pacific Ocean. After over nine months in space, they will be placed on stretchers once their capsule is opened. Returning to Earth, astronauts are temporarily unable to walk due to physical changes that occur in space. NASA implements strict safety measures to handle this.

Former NASA scientist John DeWitt explains that most astronauts prefer not to be carried on stretchers, but have to due to potential dizziness and nausea they may experience upon returning, much like motion sickness on a rollercoaster or rough waters. Hence, this precautionary measure is taken.

Sensational Shifts Post-Return
The initial sensation astronauts feel is due to Earth's gravitational pull. After spending nine months in space, Williams and Wilmore face the challenge of readjusting to Earth's gravity.
They may experience muscle and bone weakness, necessitating extensive rehab and medical monitoring. Below is a detailed glimpse of the hurdles they’ll encounter:

Gravity Readjustment...
Adapting back to Earth's gravity takes time, making simple tasks like walking and standing more difficult initially.
Rehabilitation Process...
Astronauts will undergo intensive physical therapy to regain strength and balance, involving exercises, weight training, and cardio plans.
Emotional and Psychological Impact...
Prolonged space missions affect astronauts emotionally and mentally, requiring attention and supportive measures.

Other Physical Impacts...
Symptoms like dizziness, nausea, and foot discomfort (baby feet) might challenge returning astronauts.
Sunita’s Health Insights from the Space Station...
To mitigate effects from extended space stays, astronauts have been exercising regularly. Williams noted, “We’ve been working out for nine months to brace ourselves for Earth’s gravity.”
