Scott Kelly and Mikhail Kornienko Share an Inside Look at Life in Space

On Tuesday, AOL.com caught up with NASA astronaut Scott Kelly and cosmonaut Mikhail Kornienko LIVE from the International Space Station.

Kelly and Kornienko are now eight months into a unique mission for which they're spending one full year aboard the International Space Station -- that's twice as long as the time in space spent by the typical ISS crew member.

"A year is a really long time," Kelly told AOL.com. "I feel like I've lived my whole life up here."

Kelly and Kornienko told The Associated Press during the interview, that flight controllers have given up trying to command the cargo carrier. The unmanned vessel began tumbling shortly after its launch Tuesday from Kazakhstan. The cargo ship contains 3 tons of food, water, fuel, clothes and equipment for the six station residents. Kelly says everything and everyone on board should be OK, even without this shipment. But he says it's still unfortunate. Kornienko calls it "a big concern." (NASA via AP)

The goal of the One-Year Mission is to better understand how spending long periods of time in the harsh and stressful environment of space impacts the human body and mind. Learning about the long-term effects of weightlessness and living in a microgravity environment will be key to NASA's future goal of getting people safely to Mars.

Kelly spoke about how astronauts and cosmonauts train to be mentally prepared for such a long stay away from home. "I think NASA and ... our partner agencies have a pretty good selection process for deciding who they're going to send up here as astronauts and cosmonauts ... We also do some training in ... team living, teamwork, leadership, followership ... critical skills to have for operating in such a challenging environment. For most of us ... when we get here, we're pretty well prepared for ... staying mentally strong during this type of mission.

"Occasionally you might get ... I wouldn't say depressed, but you might not feel 100% at times, and I think it's important to put the whole thing in perspective and understand the importance of what you're doing ... and [remember] eventually I'll be home someday, so that helps a little bit."

Although a year is certainly a long time to spend in space, Kelly is optimistic about the mission and the work his team is doing. "We're still able to do our work and do it with enough enthusiasm and energy to get the job done. I guess that's something I've learned a little bit since I've been here."

Kornienko explained that astronauts and cosmonauts do have techniques for countering the physical impact of living in a microgravity environment. "Of course there are changes in the body -- for example [changes] related to the musculoskeletal system -- and we are counteracting this by doing physical exercises. We have a good gym on the station."

Kornienko, however, has noticed a puzzling change in his vision. "I noticed for myself, I have better near vision. I'm not sure [why] ... the scientists [on the ground] will tell me later." Kornienko is not the first to experience vision changes after living in space.

The data Kornienko and Kelly are collecting during their year in space will ultimately be used to help prepare future space travelers for a journey to Mars. For the first time in four years, NASA is accepting applications for astronauts.

Kelly weighed in on what it's going to take future astronauts to make the ambitious journey to Mars. "For the person that goes to Mars ... certainly an operational type of background will be important," Kelly explained.

According to Kelly, the ideal candidate for a Mars mission needs to be a "jack–of–all–trades."

"On the space station, we're it. If something breaks, whether it's the electrical system, or the hardware that removes the carbon dioxide from the atmosphere, we have to fix it. If there's a science experiment, we are the ones that conduct it. Computer problems — we have to take care of those too ... Fortunately right now we have a doctor on board, but if he gets sick, one of us has to be his doctor."

"What is [also] critical is team work, and being able to work as part of a team, and it's a diverse team ... It will probably be an international effort [to get to Mars], and getting along with and working well with your international colleagues will be very important."

Kelly recently broke the record for the most time spent in space by an American, and he still has several months to go before he and Kornienko return to Earth in March 2016. Kelly also just completed his second spacewalk on November 6, spending almost eight hours floating outside the International Space Station (tied only with a tether) to perform critical maintenance tasks.

Expedition 46 Commander Scott Kelly shared photographs of a blooming zinnia flower in the Veggie plant growth system aboard the International Space Station. Kelly wrote, "Yes, there are other life forms in space! #SpaceFlower #YearInSpace"

This flowering crop experiment began on Nov. 16, 2015, when NASA astronaut Kjell Lindgren activated the Veggie system and its rooting "pillows" containing zinnia seeds. The challenging process of growing the zinnias provided an exceptional opportunity for scientists back on Earth to better understand how plants grow in microgravity, and for astronauts to practice doing what they’ll be tasked with on a deep space mission: autonomous gardening. In late December, Kelly found that the plants "weren't looking too good," and told the ground team, “You know, I think if we’re going to Mars, and we were growing stuff, we would be responsible for deciding when the stuff needed water. Kind of like in my backyard, I look at it and say ‘Oh, maybe I should water the grass today.’ I think this is how this should be handled.”

The Veggie team on Earth created what was dubbed “The Zinnia Care Guide for the On-Orbit Gardener,” and gave basic guidelines for care while putting judgment capabilities into the hands of the astronaut who had the plants right in front of him. Rather than pages and pages of detailed procedures that most science operations follow, the care guide was a one-page, streamlined resource to support Kelly as an autonomous gardener. Soon, the flowers were on the rebound, and on Jan. 12, pictures showed the first peeks of petals beginning to sprout on a few buds.

NASA astronaut Scott Kelly and ESA astronaut Tim Peake shared a series of aurora photographs taken from the International Space Station on Jan. 20, 2016. Kelly (@StationCDRKelly) wrote, "#goodmorning #aurora and the Pacific Northwest! #YearInSpace" and Peake (@astro_timpeake) followed up with, "Getting a photo masterclass from @StationCDRKelly – magical #aurora"

The dancing lights of the aurora provide spectacular views on the ground, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.
