Yearlong-Mission Astronaut Scott Kelly Honored at NYC's Fleet Week

NEW YORK — Former astronaut Scott Kelly, who set the record for the longest sojourn in space for any American after his nearly yearlong mission ended in March, was honored at the Intrepid Museum's 25th annual Salute to Freedom gala Thursday (May 26). There, he received the Intrepid 21st-Century Pioneer Award. 

Kelly returned from the International Space Station's "Year-in-Space" mission on March 2. Since then, he has retired from NASA and continues to speak at events around the country. 

On Thursday morning, Kelly met the Breitling Jet Team on the flight deck of the Intrepid. Breitling, a maker of Swiss watches, signed on as an official sponsor of Fleet Week at the Intrepid Museum, and the Breitling Jet Team has loaned its L-39C Albatros jet to the Intrepid for the duration of the event, which began May 25 and lasts until May 30.

The Year-in-Space mission was designed to study the effects on humans of prolonged space travel. Kelly, along with Russian cosmonaut Mikhail Kornienko, spent a total of 340 consecutive days in orbit.

Since returning, Kelly has spoken often of changes in his perspective after living in space for a year. He took the time to speak at Thursday's event, as well. "From orbit, it's clear that humans are polluting the planet on a significant scale," he told that morning. He noted that Earth's atmosphere is a thin layer on the planet itself, and you can see this very clearly from the space station. 

Even so, he said, he came away with a sense that humans can accomplish a lot. "I was really inspired by the space station, and how big it is," he said. "I felt like if we can do that, we can do almost anything." 

Researchers are using the data on Kelly's health in part to get a better idea of what would happen on longer trips to other planets, such as Mars. A Mars trip would require spending at least six months on a spacecraft to get there and six months to get back, plus however much time is spent on the surface. 

Beyond better understanding the health of the astronauts, Kelly said, there is still some technological development to do before such a trip. "Life support needs to be more reliable," he said. On the space station, it's possible to wait for a resupply of parts from Earth; a Mars mission wouldn't have that option. "If you're on your way to Mars and the toilet breaks, you're going to die because you run out of water." A Mars ship would also need much better radiation protection, he added. 

Another issue Kelly has faced is the transition from the microgravity conditions of the space station to full Earth gravity after the landing. Kelly said there are a variety of small physical ailments, enough that they might be significant after longer periods. Astronauts already have to exercise regularly to prevent loss of bone density. But there are other effects as well, such as disruptions to an astronaut's balance. 

"When you get back, your balance is off," he said. Initially, he felt the gravity, he said, and after about an hour he could walk normally. Getting used to the feel of gravity, though, took longer. "Sometimes it was hard getting out of bed." He said he felt some soreness as his joints got used to bearing weight again. 

While in space, one of the main things Kelly missed was fresh food, he said. Meals on the space station are akin to the prepackaged foods served to the military, though there have been efforts to improve it. Kelly also had a chance to eat lettuce grown in orbit

Many people wonder how differences among the crewmembers affect the mission, Kelly said, but that tends not to matter. "They filter a lot of that out in the selection process."

Going back in to space isn't something Kelly's ruled out completely, though for now he is retired, he said. "I'm working on a book. That's enough for now," he said.
