Zond 1967B
Encyclopedia
Soyuz 7K-L1 No.5L, sometimes identified by NASA as Zond 1967B, was a Soviet
spacecraft which was launched in 1967 as part of the Zond program
me. It was a 5390 kilograms (11,882.9 lb) Soyuz 7K-L1
spacecraft, the second of nine to be launched. It was intended to perform a circumlunar flyby of the Moon before returning to the Earth for landing, however it failed to achieve orbit.
Soyuz 7K-L1 No.5L was launched at 19:07:59 UTC on 22 November 1967 atop a Proton-K
8K78K carrier rocket with a Blok D
upper stage, flying from Site 81/24
at the Baikonur Cosmodrome
. One of the rocket's second stage engines failed to ignite, which caused the launch to be aborted and the spacecraft to separate by means of its SAS launch escape system
. The descent module came down 285 kilometres (177.1 mi) downrange. Its landing motors fired prematurely, resulting in a harder landing than expected, and the spacecraft was subsequently dragged 550 metres (1,804.5 ft) by its parachute
. It was subsequently collected by a Mil Mi-4
helicopter
. Prior to the release of information about its mission, NASA correctly identified that it had been a test of a spacecraft intended for manned Lunar flights, however they were unsure whether it was intended to reach the Moon itself..

Soyuz 7K-L1
The Soyuz 7K-L1 spacecraft was designed to launch men from the Earth to circle the Moon without going into lunar orbit in the context of the Soviet manned moon-flyby program in Moon race. It was based on the Soyuz 7K-OK with several components stripped out to reduce the vehicle weight...

Proton-K
The Proton-K, also designated Proton 8K82K after its GRAU index, 8K82K, is a Russian, previously Soviet, carrier rocket derived from the earlier Proton. It was built by Khrunichev, and is launched from sites 81 and 200 at the Baikonur Cosmodrome in Kazakhstan...

Block D
Blok D is an upper stage used on Soviet and later Russian expendable launch systems, including the N1, Proton-K and Zenit. There were plans to use it for some other rockets as well ....

Baikonur Cosmodrome Site 81
Site 81 at the Baikonur Cosmodrome is a launch site used, along with Site 200, by Proton rockets. It consists of two launch pads, areas 23 and 24. Area 24 is currently used for Proton-K and Proton-M launches, while Area 23 is currently inactive....

Baikonur Cosmodrome
The Baikonur Cosmodrome , also called Tyuratam, is the world's first and largest operational space launch facility. It is located in the desert steppe of Kazakhstan, about east of the Aral Sea, north of the Syr Darya river, near Tyuratam railway station, at 90 meters above sea level...

Launch escape system
A Launch Escape System is a top-mounted rocket connected to the crew module of a crewed spacecraft and used to quickly separate the crew module from the rest of the rocket in case of emergency. Since the escape rockets are above the crew module, an LES typically uses separate nozzles which are...

Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag, or in the case of ram-air parachutes, aerodynamic lift. Parachutes are usually made out of light, strong cloth, originally silk, now most commonly nylon...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more engine-driven rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forwards, backwards, and laterally...
