NASA astronaut Douglas Wheelock who is currently aboard the International Space Station, shares his pictures of the Earth through Twitter.

At a speed of 28,163 kilometers per hour (8 kilometers per second), we rotate the Earth's orbit, making one revolution every 90 minutes, and watch sunsets and sunrises every 45 minutes. So half of our journey is in darkness. For the work we use lights on our helmets.

Every time I look out the window and see our beautiful planet, my soul sings! I see blue skies, white clouds and bright blessed day

Another spectacular sunset. We see 16 such sunsets each day, and each of them is really valuable.

I wanted to share with you this view from the Dome. We said goodbye to the members of our group Sasha, Misha and Tracy this weekend, and they returned safely back to Earth. In this photo, Tracy quietly dreams of returning home.

In this time of year you can enjoy the beauty of the polar mesospheric clouds. With our high-angle illumination, we were able to capture a thin layer of noctilucent clouds at sunset.
