#YearInSpace

Took this photo of the Korean Peninsula during my #YearInSpace. Hopeful tonight for new light on #Korea.pic.twitter.com/5FVn5LqZTe

Happy Birthday, @Space_Station! Bittersweet final moment in the cupola before returning to Earth after my #yearinspace. Having spent 500 days of my life on ISS, I’m inspired if we can do this—the hardest thing we’ve ever done—we can do anything if we choose to & we work together. pic.twitter.com/I8I6HUinyx

Three years ago on day 340 of my #yearinspace, I captured this sunrise before returning to Earth. pic.twitter.com/nZVVR0W2V6

O #Canada! Beneath thy shining skies. You were beautiful during my #YearInSpace pic.twitter.com/Mq03UUSPrH

Still one of my favorite first moments back on our planet after a #YearInSpace. Happy #EarthDay!pic.twitter.com/IWOGzRGqXI

One stunning morning over Mexico during my #YearInSpace. #CincoDeMayo commemorates the Mexican army’s victory over the French empire at the battle of Puebla. Today’s festivities have since evolved, so for whatever reason you celebrate, Happy May 5!pic.twitter.com/hh3oz8AuwB

340 days, 143 million miles, 5,440 orbits around Earth, 10,880 sunrises and sunsets. Two years ago today, I came home after the best ride of my life! #yearinspace #anniversarypic.twitter.com/uBcJAfBKH5

Here I am in 2015 saying peace out to my twin brother @ShuttleCDRKelly before my #YearInSpace. During that year we were studied and gave a lot of blood to see how my body changed compared to his on Earth. Today, @NASA is releasing the results of what they learned.pic.twitter.com/BME5LfK2Ue

One day on my #yearinspace, I saw city lights I’d never seen before because the area had always been covered by pollution. Gov't closed coal plants that day. Everything we do impacts our planet. It’s up to us what kind of impact it will be. #WorldEnvironmentDaypic.twitter.com/qbVrBQHXnL

A #YearInSpace gave me a fresh perspective of Earth and a new appreciation for nature. Take time to enjoy our planet. Happy #firstdayofspring!pic.twitter.com/vMxmPMeyit

Earth is what we all have in common. Spending a #yearinspace gave me a unique perspective on our planet. Excited to share the natural and sometimes otherworldly beauty of our #InfiniteWonder in my new photo book on sale Oct 30! http://www.scottkelly.com  pic.twitter.com/BAPZKURcVt

Caught a glimpse of a baby aurora last night. Unfortunately I wasn’t able to photograph it. Just bought a better camera than the one I carry in my pocket that also rings. Tonight’s the night. I can feel it! Meanwhile, #aurora from my #yearinspace pic.twitter.com/iWDkRYbUgW

Took this photo of #Jamaica on my #YearInSpace. Recently visited the island up close on my 3rd year launch anniversary. Earth is good! Off to explore more of our planet. Have a great holiday weekend! pic.twitter.com/46FOpGVQTw

To understand the impacts of spaceflight, we compared changes in gene expression for identical twin astronauts - one who spent a #YearInSpace & one who remained on Earth. Discover what our experts learned as we release our Twins Study tomorrow: https://go.nasa.gov/2UvRRsc pic.twitter.com/EqmwHdkmM3

Researchers now know that 93% of @StationCDRKelly's genes returned to normal after his #YearInSpace. However, the remaining 7% point to possible longer term changes in genes related to various systems. Read more https://go.nasa.gov/2FDHzdE  pic.twitter.com/yopXPuRZlf

This week started with a spacewalk on the @Space_Station and ended with the release of results about how spending a #YearInSpace can change the human body. Find out all this and more on this week's #SpaceToGround: https://youtu.be/nQIKv5QtABM pic.twitter.com/uyt8NwEBz1

In space, I missed the weather. It seems like all the snow I missed my entire #yearinspace just fell on Iowa. It’s great to be here @IowaStateU! It’s cold out there but a lot of warm seats in the @StephensAud. Looking forward to seeing you here tonight!pic.twitter.com/WZ8GtltZgi

One of my 14 crewmates who flew with me over the course of my #yearinspace Gennady Padalka said, “When you’re in space, you miss Earth. When you’re on Earth, you miss space.” pic.twitter.com/xS3YLDM329

Most @Space_Station missions are 6 months, but in 2015-16, two crew members stayed twice as long. Their #YearInSpace provided valuable science on long space missions' effects on humans. How we'll use the research to pave the way for future exploration: https://go.nasa.gov/2FZBmNr pic.twitter.com/pgXOzuXpc3

There was never one more glorious than the other. But my last sunrise on my #yearinspace will always be a bittersweet memory. pic.twitter.com/6dgE8Q5pPk
