CAPE CANAVERAL, Fla. – From left, former NASA astronauts Robert Cabana, Gerald P. Carr and Edward G. Gibson pay their respects to former NASA astronaut William R. Pogue during a wreath laying ceremony at the United States Astronaut Hall of Fame at the Kennedy Space Center Visitor Complex. Cabana now is the director of Kennedy Space Center. In the background is a painting by former NASA astronaut Alan Bean. Col. Pogue, pilot on NASA's Skylab 4 mission in 1973-74, died March 3. He was 84 years old. Skylab 4 was the third and final manned visit to the Skylab orbital workshop, launched Nov. 16, 1973, and concluded Feb. 8, 1974. At 84 days, 1 hour and 15 minutes, Skylab 4 was the longest manned space flight to that date. Pogue was accompanied on the record-setting 34.5-million-mile flight by Commander Carr and science-pilot Gibson. They conducted dozens of experiments and science demonstrations during their 1,214 orbits of Earth. Pogue logged 13 hours and 31 minutes in two spacewalks outside the orbital workshop.
