NSSDCA also provides access to portions of their database contains information about data archived at NSSDCA (and, in some cases, other facilities), the spacecraft which generate space science data and experiments which generate space science data. NSSDCA services also included are data management standards and technologies. [1]
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.
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).
The International Designator, also known as COSPAR ID, is an international identifier assigned to artificial objects in space. [1] It consists of the launch year, a three-digit incrementing launch number of that year [n 1] and up to a three-letter code representing the sequential identifier of a piece in a launch.
Pioneer 2 (NSSDCA ID: PION2) [1] was nearly identical to Pioneer 1. It consisted of a thin cylindrical midsection with a squat truncated cone frustum on each side. The cylinder was 74 centimeters (29 in) in diameter and the height from the top of one cone to the top of the opposite cone was 76 centimeters (30 in).
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.
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.
