On November 2, 2017, Steven L. Smith concluded his career at NASA.
Smith was selected for the astronaut corps in 1992, having begun his NASA career in 1989 as a payload specialist in the Flight Operations Directorate. He was the first member of the 1992 class to receive a flight assignment and flew the first of his four space missions in 1994 aboard Endeavour STS-68, conducting Earth observations using the Space Radar Laboratory equipment.
In 1997, Smith returned to space aboard the shuttle Discovery STS-82; during the mission, he worked with the Hubble Space Telescope and performed three of the four scheduled spacewalks. In 1999, he flew again on Discovery STS-103, where he was responsible for payload operations and conducted two additional spacewalks.
Smith flew his final mission in 2002 aboard the Space Shuttle Atlantis STS-110. During the visit to the International Space Station, he served as the lead extravehicular activity (EVA) specialist, performing two spacewalks and participating in the installation of the station's first truss segment.
Over the course of these four missions, Smith performed seven spacewalks with a total duration of 49 hours and 48 minutes.
Following his final spaceflight, Smith continued to work at NASA in various roles, including as the launch preparation lead for the Automated Transfer Vehicle (ATV) across all five missions of that type, as the European Space Agency liaison for the International Space Station program, and as the deputy director of the program's science division at NASA's Ames Research Center (California).
Smith was born in Phoenix, Arizona, but considers San Jose, California, his hometown. He earned a bachelor's degree in electrical engineering, as well as two master's degrees—in electrical engineering and business administration—all from Stanford University.
