Stephen Bowen is a US Navy submariner, a NASA astronaut; and the second submariner to travel into space. He was born Stephen Gerard Bowen on February 13, 1964 in Cohasset, Massachusetts. He graduated from Cohasset High School in 1982 and went on to receive a Bachelor of Science degree in Electrical Engineering from the United States Naval Academy in 1986. He also earned a degree of Ocean Engineering from the Massachusetts Institute of Technology in 1993. Bowen is married to Deborah Alden, and together they have three children.
After he finished the submarine training pipeline, Bowen spent three years with the USS Parche (SSN-683) and completed qualification in Submarines on USS Pogy (SSN-647). After attending a joint program in Ocean Engineering, he reported to USS Augusta (SSN-710) for his assignment as the Engineering Officer. In 1997, he went to work for the United States Special Operations Command in the Office of Plans and Policy. In May 2000, he became the first Executive Officer of the Pre-Commissioning Unit Virginia (SSN-774).
Bowen was selected as the first Submarine Officer candidate by NASA in July 2000. He reported for training at the Johnson Space Center one month later, and after two years of training and evaluation, he was assigned in the Astronaut Office Station Operations Branch, while he waited for an assignment to a spaceflight as a Mission Specialist.
Bowen’s first mission was STS-126, which launched aboard Shuttle Endeavor on November 14, 2008 to the International Space Station. The crew carried a reusable logistics module that held supplies and equipment for the crew aboard the ISS. During the mission, Bowen successfully completed here spacewalks. STS-132 was Bowen’s second flight to space. The crew launched aboard Shuttle Atlantis on May 14, 2010 as the 32nd Shuttle flight to the International Space Station. The flight docked with the ISS on May 16 to deliver an Integrated Cargo Carrier and a Russian-build Mini Research Module. Throughout the week they were docked, the crew performed three spacewalks and installed a spare antenna and a stowage platform, replaced batteries on the P6 Truss, and retrieved a power data grapple fixture for future installation. The mission ended successfully with a safe landing on May 26, 2010.
