Astronaut Scott Carpenter is being remembered by friends, family and dignitaries at a funeral service in Colorado.
A public service is planned Saturday in Boulder after private family funeral.
Carpenter, who lived in Vail, Colo., died Oct. 10 at age 88.
He was the second American to orbit the Earth, following John Glenn, and Glenn is scheduled to speak Saturday.
Carpenter orbited the Earth three times in May 1962.
It was his only space flight, and he later became an undersea explorer. In 1965, he spent 30 days under the ocean in the Navy's SeaLab II program.
Gov. John Hickenlooper ordered flags lowered to half-staff in Carpenter's honor.
He is survived by his wife and six children. His ashes will be interred at his ranch near Steamboat Springs, Colo.
