HUNTSVILLE, Ala. (AP) — Alabama’s space museum is marking the 50th anniversary of the Apollo 16 lunar mission while looking ahead to the next U.S. spaceflight to the moon.

A member of the Apollo 16 crew, former astronaut Charlie Duke, will be on hand in Huntsville on Wednesday as the U.S. Space and Rocket Center looks back on the April 1972 mission.

Duke and NASA officials are among those who will participate in an event that also will focus on the space agency’s upcoming test of its new, 30-story Space Launch System rocket.

NASA is targeting June for a test flight to send the rocket to the moon without a crew.
