The head of NASA's next-generation rocket will be in Mobile to discuss the program with coastal residents.
Todd May, who directs NASA's space launch system at the Marshall Space Flight Center in Huntsville, will speak about the program at Battleship Memorial Park on Wednesday afternoon.
The event is open to the public, and NASA astronaut and former space shuttle pilot Tony Antonelli will also be on hand.
The space launch system will be the most powerful rocket ever built, and the first test flight is set for 2017.
The Marshall center manages the program for the space agency, and the Mobile Chamber of Commerce is holding a forum about working with the program.
May grew up in Fairhope, and he will also visit Fairhope High School on Thursday.
