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 ...

Luna E-6 No.8 (Ye-6 series), sometimes identified by NASA as Luna 1965A, [1] was a Soviet spacecraft which was lost in a launch failure in 1965. It was a 1,422-kilogram (3,135 lb) Luna Ye-6 spacecraft, [2] the seventh of twelve to be launched, [3] It was intended to be the first spacecraft to perform a soft landing on the Moon, a goal which would eventually be accomplished by the final Ye-6 ...
Luna E-6 No.5, sometimes identified by NASA as Luna 1964B, [1] was a Soviet spacecraft which was lost in a launch failure in 1964. It was a 1,422-kilogram (3,135 lb) Luna Ye-6 spacecraft, [2] the fifth of twelve to be launched. [3]
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.
Luna E-6 No.3, also identified as No.2 and sometimes by NASA as Luna 1963B, [1] was a Soviet spacecraft which was lost in a launch failure in 1963. It was a 1,422-kilogram (3,135 lb) Luna E-6 spacecraft, [2] the second of twelve to be launched, [3] and the second consecutive launch failure. [3]
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).
