Maj. Gen. Joe Engle, a native of Chapman, and spacecraft commander on space shuttle missions, will speak at the Cosmosphere on Friday. Then he'll be grand marshal at the Hutchinson Fourth of July parade on Saturday.
Engle was commander of the space shuttle Discovery in 1985.
On July 10, Brig. Gen. Charlie Duke Jr. will speak at the Cosmosphere about his experiences as the lunar module pilot of Apollo 16 and capsule-communications officer for Apollo 11. Duke was the 10th man to walk on the moon and had more than 21 hours in spacewalks.
The 40th anniversary of the Apollo 11 moon landing is July 20.
