R.I.P. - Astronaut Wally Schirra

Astronaut Walter M. ``Wally'' Schirra, age 84, has passed away. Schirra was the only man to fly in space in all three of the first US space programs, Mercury, Gemini, and Apollo.
Schirra was a naval officer, a combat pilot in Korea, and later a test pilot before being picked for Project Mercury. He said of his Mercury comrades: "We shared a common dream to test the limits of man's imagination and daring."

Godspeed, Wally.
