30767 Chriskraft           Discovered 1983 Nov. 6 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Christopher C. Kraft (b. 1924) oversaw the design of space modules and rocket launches from Mercury and Gemini to Apollo. He created Mission Control and was the "voice of flight" essential to men in space. His commitment to manned space flight helped pave the way for the successful landing of men on the moon.
