WASHINGTON (CBSDC/AP) — The first man to walk on the moon has been buried at sea.

NASA says Neil Armstrong’s cremated remains were buried in the Atlantic Ocean on Friday during a ceremony aboard the USS Philippine Sea.

Armstrong was a Navy fighter pilot before joining the space program. He died last month in Ohio at age 82. His burial follows a memorial service at the National Cathedral in Washington on Thursday.

NASA photographs show Armstrong’s widow, Carol Armstrong, accepting a folded American flag during the ceremony, which NASA said included a bugler and a rifle salute.

The space agency didn’t give the location of the ceremony. The ship’s homeport is Mayport, Fla.
