Already an experienced aviator and retired U.S. Navy Captain, Mark Kelly began his career as an astronaut in 1996. During his illustrious career with NASA, he spent more than 50 days in space and commanded both the Space Shuttle Endeavour, including its final flight in May 2011, and Space Shuttle Discovery, and is one of only two individuals who have visited the International Space Station on four different occasions.

Mark Kelly is also a #1 New York Times best-selling author and a founder of World View Enterprises, a company pioneering a new frontier at the edge of space.

In January 2011, Mark Kelly became the center of international attention after the assassination attempt on his wife, former U.S. Congresswoman Gabrielle Giffords. Their story captivated the nation and resulted in the couple becoming an unequivocal symbol of strength and perseverance.

Back from his historic record-breaking “Year In Space,” NASA astronaut Captain Scott Kelly has laid the groundwork for the future of space travel and exploration.

An astronaut since 1996, Scott Kelly’s achievements over his illustrious 20-year career with NASA earned him the coveted position as America’s first year-round astronaut. On his historic mission that spanned from March 2015 to March 2016, Kelly and Russian cosmonaut Mikhail Kornienko conducted experiments, reconfigured station modules, and captivated the world with live interviews and never-seen-before photos from the International Space Station.

The historic mission also included NASA’s groundbreaking Twins Study, in which Scott Kelly’s identical twin brother, retired NASA astronaut Captain Mark Kelly served on the ground as a control model in an unprecedented experiment to understand how space affects the human body.

Prior to his career with NASA, Scott Kelly served 25 years in the U.S. Navy, retiring as an experienced aviator and decorated Captain.
