Apollo 11 Command Module "Columbia"

Smithsonian Photograph
I've been up and close to the "Columbia" Command Module at the Smithsonian Air and Space Museum. It is a great exhibit.

Facts about the Apollo 11 Command Module here:

The blunt-end design for the Command Module was chosen to build upon experience gained with the similarly shaped Mercury and Gemini spacecraft. The spacecraft reentered the atmosphere with its protective heat shield facing forward. Layers of special "ablative" material on the shield were purposely allowed to burn away during reentry to help dissipate the extremely high temperatures caused by atmospheric friction.

Height: 3.2 m (10 ft 7 in)
Maximum Diameter: 3.9 m (12 ft 10 in)
Weight: 5,900 kg (13,000 lb)
Manufacturer: North American Rockwell for NASA
