S63-07135 (16 May 1963) --- This was the Nation?s sixth manned orbital space flight, and the ?Faith 7? spacecraft was piloted by astronaut L. Gordon Cooper Jr. The launch was originally scheduled for May 14, 1963, but due to a malfunction in the radar tracking system at Bermuda. The launch was ?scrubbed? 12 minutes before countdown would have been completed. At midnight, May 15, 1963, countdown was resumed and liftoff occurred at 8:04 a.m. (EST), May 16, 1963. Astronaut L. Gordon Cooper Jr., completed a total of 22.9 orbits and spent 34 hours, 20 minutes in space flight. The launch and recovery was highly successful and was the last of the Mercury flights.

As MESSENGER passes progressively closer to Mercury, we see ever more resolved features in the images the spacecraft returns. Here, at a pixel scale of 9 meters, we see the eastern portion of an unnamed crater 13 km (8 mi.) in diameter. The wall of the crater is replete with smaller, superposed craters, some of which appear elongate possibly because they impacted on the larger crater's inclined wall. Interestingly, there are bright spots on the sunlight portion of this crater's wall -- which is where we might expect hollows to form. This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

A NASA mechanic secures the afterbody to a Mercury capsule in the hangar at the Lewis Research Center. The capsule was one of two built at Lewis for the “Big Joe” launches scheduled for September 1959. The initial phase of Project Mercury consisted of a series of unmanned launches using the Air Force’s Redstone and Atlas boosters and the Langley-designed Little Joe boosters. The first Atlas launch, referred to as “Big Joe”, was a single attempt early in Project Mercury to use a full-scale Atlas booster to simulate the reentry of a mock-up Mercury capsule without actually placing it in orbit. The overall design of Big Joe had been completed by December 1958, and soon thereafter project manager Aleck Bond assigned NASA Lewis the task of designing the electronic instrumentation and automatic stabilization system. Lewis also constructed the capsule’s lower section, which contained a pressurized area with the electronics and two nitrogen tanks for the retrorockets. Lewis technicians were responsible for assembling the entire capsule: the General Electric heatshield, NASA Langley afterbody and recovery canister, and Lewis electronics and control systems. On June 9, 1959, the capsule was loaded on an air force transport aircraft and flown to Cape Canaveral. A team of 45 test operations personnel from Lewis followed the capsule to Florida and spent the ensuing months preparing it for launch. The launch took place in the early morning hours of September 9, 1959.

CAPE CANAVERAL, Fla. -- During a celebration at Complex 5/6 on Cape Canaveral Air Force Station in Florida, Mercury astronaut Scott Carpenter greets Calvin Fowler, the launch conductor for Carpenter's Mercury-Atlas 7 mission on May 24, 1962. The celebration was held at the launch site of the first U.S. manned spaceflight May 5, 1961, to mark the 50th anniversary of the flight. Fifty years ago, astronaut Alan Shepard lifted off inside the Mercury capsule, "Freedom 7," atop an 82-foot-tall Mercury-Redstone rocket at 9:34 a.m. EST, sending him on a remarkably successful, 15-minute suborbital flight. The event was attended by more than 200 workers from the original Mercury program and included a re-creation of Shepard's flight and recovery, as well as a tribute to his contributions as a moonwalker on the Apollo 14 lunar mission.
