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.6, sometimes identified by NASA as Luna 1964A, [1] and sometimes known in the West as Sputnik 27, was a Soviet spacecraft which was lost in a launch failure in 1964.
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 ...
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).
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]
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-3 No.1 was launched at 15:06:45 UTC on 15 April 1960, atop a Luna 8K72 carrier rocket, [5] flying from Site 1/5 at the Baikonur Cosmodrome. [1] The core stage and strap-ons of the 8K72 booster performed perfectly and Blok E staging and engine start went well at first, but about halfway through its burn, engine thrust and fuel system pressure began dropping, followed by cutoff.
TIROS-N satellite is the first of the TIROS-N series. It is a weather satellite launched on 13 October 1978. [2] It was designed to become operational during 2 years. Its mass is 734 kilograms. [2]
