Over the course of the year-long mission, researchers tracked changes in both brothers' biological markers to pinpoint any variances. Because the twins share the same genetic code, researchers reasoned that any observed differences could tentatively — though not definitively — be linked to Scott's time aboard the International Space Station ISS.

This allowed them to take advantage of a unique opportunity and explore how an extended stay in space may impact the human body. Based on their results, which were published last week in the journal Sciencespaceflight can definitely trigger changes in the human body. But the vast majority of these changes disappear within just a few short months of returning to Earth.

Most notably, the researchers found that living in a microgravity astronaut scott kelly height can: damage DNA; impact the way thousands of individual genes are expressed; increase the length of telomeres the shielding caps that protect the ends of our chromosomes ; thicken artery walls; modify the microbiome; and increase inflammation — just to name a few.

The Twins Study is actually composed of 10 distinct projects all wrapped into one. The individual investigations focus on how long-term spaceflight can impact different aspects of the human body, ranging from genetic expression to cardiovascular health to immune system response and more. To carry out the study, researchers performed numerous tests and collected many samples from both twins, beginning six months before Scott's flight and ending nine months after he landed.

While in orbit, Scott was responsible for collecting his own samples — which included blood, urine and fecal matter. This graphic illustrates how the individual Twins Study projects were integrated into the single summary paper that was just released. Later this year, individual projects will publish several companion papers delving into the specifics of each study.

Though both Kellys were expected to experience epigenetic changes over the course of the study, the sheer number of transformations still took researchers by surprise.

This happens as soon as an astronaut gets into space, and some of the activity persists temporarily upon return to Earth. Primarily, it turned on genes related to telomere growth, collagen production, immune system response, and DNA repair. And though such changes started soon after Scott got into space, they dramatically ramped up about halfway through his stay.

The researchers point out that Earth-bound Mark also experienced a significant number of epigenetic changes. Another important aspect of the Twins Study focused on how spaceflight altered the length of Scott's telomeres, which are the protective caps on the ends of chromosomes that prevent DNA strands from degrading as we age. Led by professor Susan Bailey of Colorado State University, this study monitored the length of each twins' telomeres before, during, and after Scott's stay aboard the space station.

Telomeres "can serve as a biomarker of accelerated aging or some of the associated health risks like cardiovascular disease or cancer," Bailey said during the press conference. Instead, they significantly increased in length. However, within just two days of Scott's return to Earth, his telomeres drastically shortened again. Though Scott's telomeres are now, on average, about the same length as they were preflight, Bailey notes that Scott currently has more very short telomeres than he did at the start of the project, which could indicate his time in space negatively affected his telomeres over the long-term.

Meanwhile, Mark's telomeres remained about the same throughout the study. The calcium loss from bones subjected to extended microgravity takes place at 10 times the rate of an elderly person suffering from osteoporosis. In an interview before heading home to Houston, Kelly said it was 'amazing' to feel the cold air when the hatch of his Soyuz capsule popped open after touchdown.

He added that the burning smell of the capsule as it was coming down surprised him. I thought it was vegetation initially. The astronaut, who has been active on Twitter throughout his stay on the International Space Station, yesterday tweeted a picture of himself boarding a plane home, alongside an astronaut scott kelly height of his astronaut scott kelly height sunset on Earth in a year.

He has also tweeted a picture of his first salad and his first flowers on Earth. He also tweeted an video of him jumping into his swimming pool after he returned home. Both Kelly, 52, and Kornienko, 55, yearned for nature throughout their day mission at the International Space Station, a dry run by Nasa for eventual trips to Mars. This is an unforgettable feeling,' Kornienko said.

It was the longest an American ever lived in space, although nothing new for the Russians. The world record is days, set back in the mids at the former Mir space station. Even before that, a pair of Soviet cosmonauts had racked up a full one-year spaceflight. This image shows the capsule on its way down to Earth. Today I head back home! Stretching my space legs on my first refuel stop.

YearInSpace,' tweeted Scott Kelly, along with an image of him getting on a plane left. The right image shows his view of the first sunset on Earth in more than a year. The year-old and two Russian cosmonauts touched down in Kazakhstan after a three-hour flight from the ISS - and Kelly was carried out of the spacecraft by a rescue team. President Obama tweeted that Scott Kelly's mission was vital to the future of American space travel.

He couldn't resist: 'Of course, it was already done 28 years ago. Kelly, Kornienko and Sergey Volkov made a textbook touchdown yesterday, with the Soyuz spacecraft landing vertically as planned at around Sergey Volkov, also of the Russian space agency Roscosmos, who arrived on the station September 4, The crew touched down southeast of the remote town of Dzhezkazgan.

The trio clambered into a Russian Soyuz spacecraft at 4. It edged away from the ISS at a speed of just four inches a second until it had crept 50ft away, when two short blasts of its rockets - known as separation burns - set Kelly on his way home. Kelly shared an emotion farewell with his crew yesterday afternoon after posting a picture of his final sunrise on Twitter, telling hisfollowers: 'Rise and shine!

Nasa will be conducting a series of tests on Scott Kelly now that he has landed back on Earth to see how his body coped with spending almost a year in space. Scott Kelly, together with cosmonaut Mikhail Kornienko, boarded the ISS in March last year as part of a first-of-its-kind experiment to test how the human body copes with prolonged space travel.

They will be the first astronauts to spend a year on the station. Mr Kelly's identical twin Mark has remained on Earth, allowing Nasa to examine the changes between these genetically identical people in two vastly different environments. Both the Kellys will be subjected to 10 experiments in human physiology, behavioural health, microbiology and molecular.

By staying on the station for 12 months, the astronauts will provide key information on how an eventual Mars mission - estimated to last three years there and back - might play out.
