NASA administrator Charles Bolden is scheduled for a stop in north Alabama.
The space agency says Bolden will visit the Marshall Space Flight Center in Huntsville on Friday afternoon.
Marshall is NASA's main center dedicated to developing space propulsion systems. Engineers there are now working on the Space Launch System, which are heavy-lift rockets being designed to take U.S. astronauts back into space.
An expert on meteors is visiting Huntsville to discuss the recent meteorite shower in north Alabama.
Marc Fries will speak at NASA's Marshall Space Flight Center on Thursday morning.
Fries is a specialist in finding and recovering meteorites. He still focus on an Oct. 30 shower across the state's northern counties as he talks about using Doppler weather radar to find meteorites on the ground.
Two meteorite fragments have been recovered in Winston County, near Addison.
