While social media users may be derided for oversharing, that's not a problem if you happen to be a NASA astronaut. Scott Kelly has spent over 330 days in space sharing photos of his meals, views of Earth and taking selfies. Kelly, along with his crew member for the last year, Russian cosmonaut Mikhail Kornienko, returns to Earth Tuesday .

Kelly has been a prolific photographer during his time aboard the space station. It takes the space station just 90 minutes to orbit the Earth at a speed of 17,895 mph. Because of its speed, an astronaut aboard the space station witnesses 16 sunrises and sunsets every day. For a photo enthusiast, that's a dream come true. Kelly has been documenting his life in space via Twitter, Instagram and Tumblr.

Through his year in space, Kelly has captured aurora, bright cities at night, the formation of hurricanes and thunder snow. Kelly's photos also helps illuminate certain realities of what life is like in different areas of the world. In one photo, South Korea shines bright while North Korea, save for its capital Pyongyang, is shrouded in darkness.

At times, Kelly's photographs of natural formations on Earth appeared to be abstract works of art.

When Kelly was not busy pointing his camera outward, the astronaut documented his daily life aboard the space station. Meals were slightly different in space, but there was coffee thanks to the ISSpresso machine. Astronaut quarters were pretty cozy with a sleeping bag replacing a bed in space. Kelly, a huge Houston Texans fan, was able to watch his favorite football team from space. There were even movie nights. Kelly watched "The Martian" and "Gravity" aboard the space station.


Kelly launched to the space station aboard a Soyuz spacecraft March 27, 2015. Data collected during the one-year mission will help pave the way for a future manned mission to Mars. As a twin, Kelly presents a unique opportunity to study the effects of space on a genetic level. While Kelly has been aboard the space station, his brother, retired astronaut Mark Kelly, has been on Earth. The brothers have had samples collected and participated in a set of 10 tailored investigations as part of the mission.

Over the course of the 338 days, Kelly participated in over 400 science investigations aboard the space station. These probes examined the effects of microgravity on the human body. Other aspects of Kelly's research focused on how fruits and vegetables grow in space, fluid dynamics in microgravity and radiation measurements. Kelly also completed three spacewalks during his time aboard the space station.
