Kelly and his roommate for nearly a year, Russian cosmonaut Mikhail Kornienko, will check out of the International Space Station Tuesday night.

By the time their Russian capsule lands in Kazakhstan on Wednesday, the pair will have circled the world 5,440 times and experienced 10,880 orbital sunrises and sunsets.

Kelly, who began his mission to the International Space Station on March 27, 2015, has been an active tweeter this past year, sending nearly 1000 photos from space to his Twitter account, including breathtaking photos of sunrises, blizzards and other storms.

Tuesday morning, Kelly tweeted photos of his final sunrise from the International Space Station.

Kelly said the hardest part about serving a year in space was being away from loved ones.

"The hardest part is being isolated from people on the ground who are important to you," he said.

Even still, Kelly said it will be hard to return to Earth.

"I'll probably never see it again," he told CNN's Dr. Sanjay Gupta. "I've flown in space four times now, so it's going to be hard in that respect, but I certainly look forward to going back to Earth. I've been up here for a really long time and sometimes, when I think about it, I feel like I've lived my whole life up here."
One aim of Kelly's year in space was to examine the what happens to the human body in space, including how it affects the eyes, brain, bones and muscles. 
NASA Television will provide live coverage as Scott and his crew members return to Earth and depart the ISS.
