00:00Oh looks like we're getting our next crew member here. That is none other than Sunny Williams.
00:05After nine unexpected months in space, Sunita Williams is finally home.
00:10But stepping back onto Earth won't be easy. Just like astronauts before her,
00:14she will have to relearn how to walk, balance, and even stand without collapsing.
00:19Spending time in space wrecks the human body. Muscles weaken, bones lose calcium,
00:24and the heart shrinks slightly. In extreme cases, astronauts struggle to walk and have to be
00:28carried out on stretchers. Sunita will immediately enter NASA's rehab program designed to restore
00:34astronauts' strength after months of floating. After her 289-day mission, Peggy Whitson took
00:3945 days to regain her full strength. And Russian cosmonaut Valery, he spent 437 days in space.
00:45When he returned, his body had lost so much coordination that even standing still was a
00:50challenge. Sunita's rehab will include intense physical therapy, treadmill training, balance
00:55exercises, and resistance workouts. She'll also have to fight space-induced dizziness and baby
01:00feet, where even simple movements feel impossible. And then there's the psychological side. Many
01:06astronauts experience something called the overview effect, a profound shift in how they
01:10see the world after looking at Earth from space. It'll take weeks, maybe months for Sunita to fully
01:15recover. But after 9 months in space, she's got one mission left, learning how to live on Earth again.
