Acccording to a TODAY news report, identical twin astronauts Scott and Mark Kelly are participating in a unique NASA study looking at the effects of long-term space missions on the human body. The goal: insights into what could happen to humans on a mission to Mars.

As part of the study, next year Scott Kelly will travel with Russian cosmonaut Mikhail Kornienko to the International Space Station and spend a year there, the longest time any American has ever spent aboard the orbiting outpost. Meanwhile, his twin brother Mark will remain home in Arizona with his wife, former U.S. Rep. Gabrielle Giffords, over the same time period.

Blood, saliva, cheek swab and stool samples will be taken from both brothers at the same times before, during and after the one-year mission to study the effects of long space missions on the human body. Psychological and physical performance tests will also be conducted.

“Our genes when the eggs split were exactly the same, and since then, the environment has changed them somewhat, but they’re pretty much similar, except he got the mustache gene,’’ Scott joked with Matt Lauer and Savannah Guthrie on TODAY Friday. “I didn’t get that one. In any case, they want to look at what the space environment has done to my RNA, DNA, proteins, those kind of things in my body.”

“The space environment is pretty severe,’’ Mark said on TODAY. “There’s a lot of radiation involved that can affect your genes and your DNA and those things at the smallest level.”

The brothers, who turned 50 last month, are the only twins and only siblings to have ever flown in space, although they were not there at the same time. Scott raised the question of whether a study like this had ever been done, resulting in it becoming an official plan.

Mark retired from NASA in 2011 to be with Giffords, who was shot in the head in Tucson, Ariz., in January 2011 and has made a remarkable recovery.

“For me, I don’t work at NASA any more,’’ Mark said. “I left after my wife was injured, so it allows me to still participate in some way. [Scott and I] never got to fly in space together, so this was some way [to participate together].”

The Marana capital improvements improvements are expected to take years to complete as Marana finds the best plan of action to complete the projects and fund the improvements. Do you think this is a good idea?

The town of Marana is looking at ways to do capital improvements to the oldest neighborhoods in Marana. Over the next few months the town will survey older neighborhoods and see what amenities they need and form a plan to make sure neighborhoods have paved roads, sidewalks, adequate drainage, lighting and even pocket parks. “We want to make sure that every neighborhood has a base standard for infrastructure,” said Marana Town Manager Gilbert Davidson. The improvements are expected to take years to complete as Marana finds the best plan of action to complete the projects and fund the improvements. Do you think this is a good idea?

How do you feel about a potential memorial art project to honor our community’s bravest men and women?

During the Jan. 20 town council meeting, a vote was unanimously passed to look into the feasibility of a “Memorial Public Art Project,” at the request of Oro Valley resident Dick Eggerding to potentially be placed somewhere in the town to honor military veterans and first responders. Though no concrete plans were then ready to act on, there was a show of overwhelming support for such project from residents and staff alike during the council meeting. In an effort to poll to community at-large, The Explorer would like to know how you feel about a potential memorial art project to honor our community’s bravest men and women.
