This mission was NASA's second attempt to simulate sending a lunar lander into orbit. All systems worked without fault.
Aug. 11, 1965: Launch
Sept. 11, 1965: Spacecraft reentered Earth's atmosphere
This was the second attempt by NASA to launch a dummy Surveyor lunar lander spacecraft into a barycentric orbit toward a simulated Moon landing. Unlike the previous attempt in March 1965, this time all systems worked without fault.
The Centaur fired flawlessly and put the Surveyor dynamic model on a simulated lunar trajectory so precise that it would have impacted on the Moon without a trajectory correction.
Orbital parameters were 102 x 510,900 miles (164 × 822,135 kilometers) at 28.6-degree inclination. The payload reentered Earth's atmosphere after 31 days.
