Who Are Scott and Mark Kelly?
Before diving into the specifics of their relationship, let’s first introduce these remarkable individuals. Scott Kelly and Mark Kelly are not your average brothers. Both are retired NASA astronauts who have accomplished feats that most people only dream of. They’ve spent countless hours orbiting our planet, conducting experiments, and even walking in space.
Scott Kelly, born on February 21, 1964, became widely known for his year-long mission aboard the International Space Station (ISS), where he spent 340 consecutive days in space. Meanwhile, Mark Kelly, also born on February 21, 1964—yes, they’re twins—was a commander of four space shuttle missions and played a key role in several critical missions.
Biographical Data of the Kelly Brothers
Here’s a quick glance at their biographical details:
| Name | Birth Date | Occupation | Notable Achievements |
|---|---|---|---|
| Scott Kelly | February 21, 1964 | Retired NASA Astronaut | Spent 340 days in space during the "Year in Space" mission |
| Mark Kelly | February 21, 1964 | Retired NASA Astronaut & U.S. Senator | Commanded four space shuttle missions |
Are Scott and Mark Kelly Really Twins?
Yes, Scott and Mark Kelly are indeed identical twins. Born on the same day in Orange, New Jersey, they’ve shared an extraordinary bond since birth. Being identical twins means they share the exact same DNA, which made them perfect candidates for NASA’s groundbreaking study on how space affects the human body.
Their identical genetics provided scientists with a unique opportunity to compare Scott’s physical and mental changes during his year-long mission in space with Mark’s condition back on Earth. The results of this study were nothing short of amazing, offering insights into the long-term effects of space travel on human health.
What Does It Mean to Be Identical Twins?
Being identical twins means Scott and Mark share the same genetic makeup. This means they look alike, have similar physical traits, and even share certain personality characteristics. However, their experiences in life, especially their time in space, have shown that environment plays a significant role in shaping who they are.
- Scott spent a year in space, leading to noticeable changes in his body, such as increased telomere length and altered gene expression.
- Mark remained on Earth, providing a baseline for comparison in the NASA twin study.
The NASA Twin Study: Scott vs. Mark
The NASA Twin Study is one of the most famous scientific experiments involving Scott and Mark Kelly. This study aimed to understand the effects of long-term space travel on the human body by comparing Scott’s health after a year in space with Mark’s health on Earth.
Scientists conducted numerous tests, including analyzing their DNA, microbiome, and cognitive abilities. Some of the key findings include:
- Scott experienced changes in his gut microbiome, likely due to the microgravity environment.
- His telomeres, the protective caps at the ends of chromosomes, became longer in space but returned to normal after returning to Earth.
- There were noticeable differences in gene expression between the brothers, indicating the impact of space on cellular function.
Why Was the Twin Study Important?
The Twin Study was groundbreaking because it provided valuable insights into how the human body adapts to space. These findings are crucial for planning future missions, such as sending humans to Mars, where astronauts will spend years away from Earth.
By studying identical twins, scientists could isolate the effects of space from genetic factors, giving them a clearer picture of the challenges astronauts face during long-duration missions.
Family Life and Personal Background
Scott and Mark Kelly grew up in a humble household in New Jersey. Their mother, Janet, was a police officer, and their father, Richard, worked as a police detective. Despite facing financial challenges, the Kelly family instilled strong values in their sons, encouraging them to pursue their dreams.
Both brothers developed a passion for aviation early in life, inspired by their parents’ dedication and love for adventure. This passion eventually led them to join the U.S. Navy and later become astronauts.
How Did They Become Astronauts?
The path to becoming an astronaut wasn’t easy for Scott and Mark. After graduating from high school, they both attended the U.S. Merchant Marine Academy, where they earned degrees in marine engineering. They then joined the Navy, where they became test pilots and accumulated extensive flight experience.
Their exceptional skills and dedication caught the attention of NASA, which selected them as astronaut candidates in 1996. From there, they embarked on a journey that would take them to the stars.
Career Highlights of Scott and Mark Kelly
Both Scott and Mark Kelly have had illustrious careers in space exploration. Here’s a look at some of their most notable achievements:
- Scott Kelly: Commanded Expedition 45 and served as a flight engineer for Expedition 46 on the ISS. He also participated in the groundbreaking "Year in Space" mission.
- Mark Kelly: Commanded four space shuttle missions, including STS-108, STS-118, STS-124, and STS-134, the final mission of the Space Shuttle Endeavour.
What Made Their Missions Unique?
Each mission undertaken by Scott and Mark Kelly was unique in its own way. For instance, Scott’s "Year in Space" mission provided invaluable data on the effects of prolonged exposure to microgravity, while Mark’s final mission on the Space Shuttle Endeavour helped complete the construction of the ISS.
