The director of NASA's Marshall Space Flight Center in Alabama is retiring.

Marshall officials say Todd May announced his retirement to employees yesterday. It is set to take effect July 27.

A statement from U.S. 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.
