Memorial Service at National Cathedral for Neil Armstrong on Sept. 13

A public memorial service for Neil Armstrong, the first man to walk on the Moon, has been scheduled for September 13, 2012 at the National Cathedral in Washington, DC.

The service will begin at 10:00 am ET.  The NASA announcement says that a "very limited number of seats" are available to the public, even though it is described as a public memorial service.  The event will be covered by NASA TV.

A private service was held near Armstrong's home outside of Cincinnati, Ohio on Friday.
