【题目】

Living in space is common to astronauts. But what if it is a task of nearly a year? US astronaut Scott Kelly was in the International Space Station (ISS) for 340 days. It is the longest time a US astronaut has spent in space at a time. Kelly's stay is part of the Twins Study. When Scott Kelly spent nearly a year in the ISS, his twin brother Mark Kelly lived on Earth. They gave scientists more ways to study human space flight. Usually living in the ISS for such a long time is boring. Was it the same for Kelly? Let's take a look.

Good morning, everyone!

It's time to enjoy a sunrise. But for Kelly, it was one of the 16 sunrises he saw each day in the ISS. Isn't that cool?

Work comes first.

During his stay, Kelly and his partners did about 400 science experiments. One of them was about planting vegetables. And they did it! Growing vegetables will be helpful for longer space journeys.

Moving with microgravity (微重力).

As we all know, space is a place with microgravity which influences human bodies. So Kelly did exercise more than 700 hours in the ISS. That is about two hours of exercise a day. Microgravity also makes some easy things difficult. Kelly often slept in a sleeping bag, or his arms would float (瓢浮)in front of him all the time.

Boring? Why not do something for fun?

Kelly loved taking photos from space and sharing them with the world online. Even President Obama is his fan. Under one of his photos, Obama wrote, "Hey, loving the photos. Do you ever look out of' the window and just freak out(吓坏了)?" "I don't freak out about anything, Mr. President except getting a question from you." Kelly replied.
