Astronaut Scott Kelly’s DNA doesn’t match twin Mark’s after year-long space mission

Astronaut Scott Kelly’s DNA No Longer Matches Twin Brother After Year-Long Space Mission

By Natalie Dreier, Cox Media Group National Content Desk

A trip to space would be a life-changing experience. But scientists didn’t realize how much it changes astronauts when it comes to the building blocks of life.

NASA sent astronaut, and twin, Scott Kelly, to the International Space Station for a one-year mission to study the effects of space on the human body, KTLA reported

Scott Kelly was in space from March 2015 to March 2016, Newsweek reported.

His identical twin brother Mark kept his feet firmly planted on Earth. 

The two men were identical, down to their cellular level, before the trip, but that can’t be said now. 

Scott now differs from Mark when it comes to their DNA.

Getting into the science specifics. 

Scientists looked at the spaceman’s metabolites, cytokines and proteins before and after his voyage. They said the mission caused Scott’s “space genes” to switch on, and they didn’t turn off after he returned to Earth. The experts believe they were turned on because of the stress of space travel, KTLA reported.

NASA said in the study that Scott’s cells showed changes in the length of telomeres, the ends of chromosomes that show biological aging. They were lengthened while he was in space, but they returned to almost normal days after he landed. There was also damage to his DNA that was caused by radiation and the restriction on his calories. His collagen, blood clotting and bone formation also changed and because of zero gravity and fluid shifts.

Kelly’s year-long trip in space was a precursor to planned three-year missions to Mars. Scientists needed to test how space missions that are longer than what is currently done impacts astronauts, KTLA reported.

Kelly may have conquered the final frontier, but, as it turns out, even he is vulnerable to social media hacking:

This week, three tweets appeared on Kelly’s Twitter that sent the internet into a free fall as people tried to decipher their meanings.

After tweeting at foxnews.com, hacker “Kelly” turned to Cardi B, posting how he wanted to discuss collaborative ideas and requesting the Bodak Yellow queen to DM him.

Fans assumed “Kelly’s” proposal to be for mashup, which many thought would be out of this world.

Hundreds Retweeted the Cardi B posts from “Kelly” within the first 30 minutes.

Although the tweets suggest he is trying rocket into Cardi B’s DMs, Kelly shared follow-up comments explaining that he believed his account to be compromised:

Despite real Kelly’s clarification on the situation, some believe he accidentally searched for the terms “Cardi B” and “foxnews.com” in the space for writing tweets.

For her part, Cardi B did not tweet a response, so the world may never know if she’d be down to record a track with the world record-holder for most days spent in space.
