Astronaut and Instagram star Scott Kelly is about to set a course home to Earth after spending 340 days in space, a record for a NASA astronaut.
Kelly is scheduled to undock with the International Space Station on Tuesday. Less than four hours later, he'll land in Kazakhstan.
Kelly's year in space has been a critical mission for NASA, helping to reveal details that will be key to future missions to Mars, such as how the human body reacts to long-term stays in zero gravity.
During his time in space, Kelly drank nearly 200 gallons of recycled urine and sweat and traveled over 140 million miles, according to The New York Times. Here are some more extreme numbers from The Times about Kelly's historic time in space:
