INDIANAPOLIS (AP): Indiana Gov. Mike Pence has directed flags at state facilities statewide be lowered to half-staff to honor the memory of former astronaut and statesman John Glenn.

Pence on Friday also asked Indiana businesses and residents to lower their flags to half-staff to honor Glenn. Flags are to remain at half-staff until sunset on the day of Glenn’s burial.

Glenn died Thursday at age 95. He was the first American to orbit the Earth in 1962 and the oldest man in space at age 77 in 1998. A U.S. Marine and combat pilot, he also served as a U.S. senator from Ohio for more than two decades.

Glenn is to be buried at Arlington National Cemetery near Washington, D.C.
