HUNTSVILLE, Ala. (AP) -- The director of NASA's Marshall Space Flight Center in Alabama is retiring.
Marshall officials say Todd May announced his retirement to employees at the Huntsville facility on Monday. It takes effect July 27.
A statement from Rep. Mo Brooks of Huntsville says May is being replaced on an acting basis by Marshall's deputy director, Joan A. "Jody" Singer.
May was first named acting director of Marshall in 2015 and then took over the position on a permanent basis. Before that, the Fairhope native managed the Space Launch System, NASA's heavy-lift rocket that's still in development.
Marshall is NASA's chief center for rocket propulsion. It has more than 6,000 government and contractor workers in north Alabama and at NASA's Michoud Assembly Facility in New Orleans.
