Frederick Doyle, 93, a photographic mapping specialist whose work included space photography for NASA, photo reconnaissance from spy satellites, and high-resolution photos of Earth's surface from outer space, died April 17 at his home in McLean, Va. He had congestive heart failure, said his daughter Margaret Grant.

In 1969, Mr. Doyle became chairman of NASA's Apollo Orbital Science Photographic Team, and he planned the camera systems for Apollo lunar missions 13 through 17. He later directed photography projects on Mariner and Viking missions to Mars, Venus, and Mercury. - Washington Post
