That day marks the 10 th anniversary of the Columbia accident. Columbia and its crew were lost 15 minutes before landing at NASA's Kennedy Space Center, Fla., when unknown damage to its wing allowed heating from entry to cause high-speed aerodynamic breakup of the vehicle at an altitude of about 200,000 feet over east Texas. Ochoa was named director of JSC on Jan. 1 when her predecessor, Mike Coats, retired. She previously was deputy director and director of Flight Crew Operations, and was an astronaut serving on four space shuttle missions before moving into management positions. McArthur currently is director of JSC's Safety and Mission Assurance office. He previously was manager of the shuttle Orbiter Projects Office and served as a crew member on three shuttle flights and one long-duration expedition on the International Space Station.
