For the past twelve months, American astronaut Scott Kelly has been moving at 4.76 miles per second in a continuous loop around the globe as commander of the International Space Station.A veteran astronaut and New Jersey native, Kelly left the planet on March 27, 2015 until rescinded his command of the ISS on February 29, 2016 and returning to Earth on March 1.During his record-breaking time in space–Kelly is now the American who has spent the most time off of the planet–Scott was not only being studied for physical and mental changes (as compared to his twin brother, an astronaut who remained on Earth), but he performed many studies as well. Foremost among this was his observations of the planet and its climates: "I feel more like an environmentalist since I've been up here," he said. "There are parts of the Earth that are covered with pollution all the time. I saw weather that was unexpected. Storms bigger than we've seen in the past. This is a human effect. This is not a natural phenomenon."
