NSSDCA also serves as NASA's permanent archive for space physics mission data. It provides access to several geophysical models and to data from some non-NASA mission data. NSSDCA was called the National Space Science Data Center (NSSDC) prior to March 2015. NSSDCA supports active space physics and astrophysics researchers. Web-based services ...
The mission experienced a helium leak in the system that pressurized the liquid-fuel vernier engines that could have resulted in failure. An improvised landing sequence which started the retrorocket just 42 km above the Moon (about half the usual height) allowed the vernier engines to bring the craft down in 106 seconds from a height of only 1340 m (about 10% of the usual).
Surveyor 3 is the third lander of the American uncrewed Surveyor program sent to explore the surface of the Moon in 1967 and the second to successfully land. It was the first mission to carry a surface-soil sampling-scoop.

Surveyor 6 is the sixth lunar lander of the American uncrewed Surveyor program that reached the surface of the Moon.Surveyor 6 landed on the Sinus Medii.A total of 30,027 images were transmitted to Earth.
Surveyor 1 was the first lunar soft-lander in the uncrewed Surveyor program of the National Aeronautics and Space Administration (NASA, United States).This lunar soft-lander gathered data about the lunar surface that would be needed for the crewed Apollo Moon landings that began in 1969.
Surveyor 7 was sent to the Moon in 1968 on a scientific and photographic mission as the seventh and last lunar lander of the American uncrewed Surveyor program.With two previous unsuccessful missions in the Surveyor series, and with Surveyor 7's landing success, Surveyor 7 became the fifth and final spacecraft in the series to achieve a lunar soft landing.
Mars Global Surveyor (MGS) was an American robotic space probe developed by NASA's Jet Propulsion Laboratory and launched November 1996. MGS was a global mapping mission that examined the entire planet, from the ionosphere down through the atmosphere to the surface. [1]
