A veteran of two spaceflights, Daniel Tani has left a lasting impact on space operations and astronautics.

Daniel Tani began his NASA career in 1993 and was selected as an astronaut candidate in 1996. He served as Mission Specialist 2 on STS-108 Endeavour in December 2001, where he helped deliver the Expedition 4 crew to the International Space Station (ISS) and performed a spacewalk to wrap thermal blankets around the station’s solar array gimbals. The mission completed 185 Earth orbits, traveling 4.8 million miles.

In 2007, on his second spaceflight, Tani spent 120 days aboard the ISS as Expedition 16 Flight Engineer. During this mission, he conducted numerous robotic operations and logged nearly 35 hours during five spacewalks. After his NASA career, he became Vice President of Mission and Cargo Operations at Orbital Sciences Corporation.
