Biography of Scott and Mark Kelly
Personal Data
Scott Kelly and Mark Kelly were born on February 21, 1964, in Orange, New Jersey. They are identical twins and share a remarkable bond, both personally and professionally. Below is a summary of their personal data:
| Name | Scott Kelly | Mark Kelly |
|---|---|---|
| Date of Birth | February 21, 1964 | February 21, 1964 |
| Place of Birth | Orange, New Jersey | Orange, New Jersey |
| Occupation | Retired NASA Astronaut | Retired NASA Astronaut |
| Marital Status | Married to Amiko Kauderer | Married to Gabrielle Giffords (former U.S. Congresswoman) |
| Education | Bachelor's in Marine Engineering, Master's in Aeronautical Engineering | Bachelor's in Marine Engineering, Master's in Aeronautical Engineering |
Early Life and Education
Scott and Mark Kelly grew up in a modest household in New Jersey. Neither of their parents attended college, but they instilled in their sons a strong work ethic and a passion for learning. Both brothers pursued degrees in marine engineering and later earned master's degrees in aeronautical engineering, setting the foundation for their future careers in aviation and space exploration.
Interestingly, both Scott and Mark joined the U.S. Navy after completing their studies, where they honed their skills as test pilots. This experience was crucial in preparing them for their eventual roles as NASA astronauts.
Career Journey in NASA
Becoming Astronauts
The Kelly brothers were selected by NASA in 1996 to become astronauts. Their rigorous training and exceptional skills quickly made them standout candidates for space missions. Over the years, they participated in multiple spaceflights, contributing to critical scientific research and the construction of the International Space Station (ISS).
Space Missions
- Scott Kelly: Scott completed four spaceflights, including a one-year mission aboard the ISS, which was part of the groundbreaking Twin Study.
- Mark Kelly: Mark participated in four space shuttle missions, logging over 54 days in space.
The Twin Study: A Breakthrough in Space Science
One of the most significant contributions of the Kelly brothers to science is the NASA Twin Study. This study aimed to investigate the effects of long-term spaceflight on the human body by comparing Scott, who spent nearly a year aboard the ISS, with Mark, who remained on Earth as a control subject.
Key findings from the study include changes in gene expression, telomere length, and gut microbiome composition. These insights are invaluable for future long-duration space missions, such as those to Mars.

Key Differences Between Scott and Mark Kelly
While Scott and Mark Kelly are identical twins, their experiences in space have led to noticeable differences. For instance:
- Scott's time in space caused changes in his gene expression, which were largely reversible upon returning to Earth.
- Mark, who remained on Earth, did not experience these changes, highlighting the profound impact of microgravity on the human body.
Notable Achievements
Scott Kelly
Scott Kelly holds the record for the longest single spaceflight by an American astronaut, spending 340 days aboard the ISS during his one-year mission. His work on the ISS contributed significantly to our understanding of the effects of prolonged space travel on human health.
Mark Kelly
Mark Kelly is not only a celebrated astronaut but also a public advocate for space exploration and science education. He has been actively involved in promoting STEM (Science, Technology, Engineering, and Mathematics) programs and inspiring the next generation of scientists and engineers.
Scientific Contributions
The research conducted on the Kelly brothers has provided invaluable data for future space missions. By studying the effects of space travel on identical twins, scientists have gained a deeper understanding of the physiological and genetic changes that occur in space. This knowledge will be crucial for planning and executing long-duration missions, such as those to Mars and beyond.
Public Life and Advocacy
Both Scott and Mark Kelly have embraced their roles as public figures, using their platform to advocate for science education and space exploration. Mark, in particular, has become a prominent voice in U.S. politics, running for public office and championing causes related to gun control and climate change.
Comparison of Their Careers
While both Scott and Mark Kelly have achieved remarkable success as astronauts, their careers have taken slightly different paths. Scott's focus has been on long-duration space missions and the scientific research conducted during these flights. Mark, on the other hand, has expanded his influence beyond space exploration, becoming a political figure and advocate for various social issues.
Conclusion
Scott Kelly and Mark Kelly are indeed related, sharing not only a familial bond but also a passion for space exploration and scientific discovery. Their contributions to NASA and the broader scientific community have been invaluable, particularly through the groundbreaking Twin Study. As identical twins, they have provided unique insights into the effects of space travel on the human body, paving the way for future missions.
