Orbital chart. Color lithograph. 8.5 x 33 inches.
All six orbits of the Mercury Atlas 8 flight are plotted with circles representing the ground coverage foot print of the Mercury world-wide tracking stations. The launch is described: near the Cape Canaveral area of the chart with: "7:15 am, 3 Oct '62" and the flight time "9 hr 13m" close to the splashdown bull's eye near Midway Island in the Pacific. Near the Canton Island site tracking circle in the western Pacific Ocean, Schirra comments on the performance of Sigma 7: "She is really performing like a jewel! CANTON Orbit #2, Wally Schirra." Walter Marty Schirra Jr. was an American naval aviator and NASA astronaut. In 1959, he became one of the original seven astronauts chosen for Project Mercury, which was the United States' first effort to put human beings into space.
