Since NASA Armstrong Flight Research Center is located on Edwards Air Force Base, only military, those who can access the base as credentialed civil service and government contractors, or those who have visitor permits will be admitted. There is a NASA gift shop and Visitors' Center that you can visit if you are on the base.
Unfortunately Armstrong tours were canceled a few years ago due to budget cuts. Below is a link for the Orion Launch and splashdown that will all be seen on NASA TV. https://www.youtube.com/watch?list=PLiuUQ9asub3RHqKdK_XZSZ8I_981UPhvX&v=qZxXh0Yh5gI
Public tours of Edwards Air Force Base are still being offered by the Air Force Test Center's public affairs office. The Edwards tours include a visit to the Air Force Test Center museum as well as a bus tour of the main base area.
