The Twins Study helps NASA gain insight into what happens to the human body in space beyond the usual six-month International Space Station missions previously studied in other astronauts. Research into how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight is needed before astronauts are sent on journeys that would triple the time humans have spent in space so far. InsideEdition.com's Mara Montalbano (https://twitter.com/MaraMontalbano) has more.

Scott Kelly spent on year on the International Space Station. Scientists stated that spaceflight is associated with oxygen-deprivation stress, increased inflammation and dramatic nutrient shifts that affect gene expression and the team focused on chemical changes in RNA and DNA to better understand the genetic dynamics of each twin.

Those researchers found that 93 percent of Scott's genes became "normal" again shortly after he returned to earth.

But the Kelly brothers are still identical twins, NASA clarified Thursday evening.

Kelly said he was surprised by that change in a recent interview with Marketplace.

Though Scott Kelly's genetic expression changed, he and Mark are still identical.

While 93% of Kelly's genes went back to normal after a few days back on Earth, the remaining 7% could spell longer term changes to his immune system, DNA fix, bone formation networks, hypoxia, and hypercapnia.

'When he went up into space it was like fireworks of gene expression, ' Christopher Mason, a principal investigator on the NASA twins study and an associate professor at Weill Cornell Medical College, told Business Insider. Others involved changes in the epigenome - a sort of genetic control system that determines how genes are expressed. DNA changes weren't the only differences in Scott's body, either.

- Scott's telomeres on the ends of his chromosomes in his white blood cells lengthened while in space. The telomeres shortened when he returned.

Telomeres are involved in the fix of damaged DNA and key to preventing ageing, and the find may help us better understand how and why we age. A mission to Mars will take up to three years, depending on how long astronauts remain on the Red Planet. They returned to normal within two days of landing back on Earth.
