Meet the Kelly Brothers
Before we blast off into their space careers, let's meet the Kelly brothers. Born in 1960 and 1964, respectively, Mark and Scott grew up in West Orange, New Jersey. Their father was a police officer, and their mother was a homemaker. From a young age, both brothers showed an interest in aviation, but little did they know that their passion would one day take them to the stars.
Mark Kelly: The First to Launch
Mark Kelly, the older brother, graduated from the U.S. Naval Academy in 1987 and was commissioned as a naval aviator. He then went on to become a test pilot and later a naval aviator. In 1996, he was selected by NASA as an astronaut candidate. His first space mission was in 2001 aboard the Space Shuttle Atlantis. Since then, he's completed four space missions, spending a total of 50 days in space. But that's not all, folks. Mark's also commanded three spaceflights and served as the director of the NASA Space Shuttle Program.
Mark's Most Memorable Mission
One of Mark's most memorable missions was the STS-124 flight in 2008. During this mission, he and his crew delivered the Japanese Experiment Module (Kibo) to the International Space Station (ISS). This was a significant moment in space history, as it marked the largest piece of the ISS ever launched at that time.
Scott Kelly: The Year in Space
While Mark was making waves in the space community, Scott was following close behind. After graduating from the U.S. Merchant Marine Academy in 1987, Scott joined the Navy and became a naval aviator. He was later selected as an astronaut candidate in 1996, the same year as his brother. Scott's first space mission was in 2001, just like Mark, but it was his 2015-2016 mission that truly set him apart.
The Year-Long Mission
In 2015, Scott embarked on a year-long mission aboard the ISS. This was part of NASA's Twins Study, which aimed to understand how space travel affects the human body. During this mission, Scott broke the U.S. record for the most time spent in space by an American astronaut. He also conducted numerous scientific experiments and even grew some space lettuce!
The Twins Study
The Twins Study was a fascinating aspect of Scott's year-long mission. As twins, Mark and Scott provided a unique opportunity for scientists to study the effects of space travel on the human body. While Scott was in space, Mark stayed on Earth, allowing scientists to compare the brothers' genetic material and biological samples.
What They Found
The study found that Scott's genes changed slightly while he was in space, with some genes turning off and others turning on. These changes were temporary, and most of Scott's genes returned to their normal state after he came back to Earth. However, some changes persisted for up to six months post-flight. The study also found that Scott's telomeres, the caps at the ends of our chromosomes, grew longer during his time in space.
Life After Space
After retiring from NASA in 2016, Scott has become an advocate for space exploration and the importance of scientific research. He's written a book about his experiences, Endurance: A Year in Space, a Lifetime of Discovery, and has given numerous talks about his time in space.
Mark, on the other hand, retired from NASA in 2011 to focus on his family and political career. He later ran for the U.S. Senate in Arizona in 2018 but was unsuccessful. Despite this, Mark remains a prominent figure in the space community and continues to advocate for space exploration.
The Kelly Brothers' Legacy
Mark and Scott Kelly have made significant contributions to the field of space exploration. Their missions have helped advance our understanding of the universe and the effects of space travel on the human body. Moreover, their story serves as an inspiration for aspiring astronauts and space enthusiasts alike.
So, there you have it, folks! The incredible story of Mark and Scott Kelly, the twin astronauts who have left their mark on the final frontier. Their journey is a testament to the power of curiosity, determination, and sibling rivalry (just kidding, folks!). Until next time, keep exploring!
