  Zenit rocket facilities in Baikonur
Traditionally for the Russian rocketry, the Zenit is assembled and transported to the launch pad in horizontal position on a rail transporter.
The Zenit rocket inherited from the past an assembly and processing complex in Area 42, which was previously served R-16 and later R-36-type ballistic missiles.
The test version of the Zenit rocket is on the right, the main rail tracks used to deliver stages and to roll out the vehicle to the launch pad is in the center.

  Zenit rocket - Wikipedia, the free encyclopedia
Zenit was build in the 1980s for two purposes: as a Liquid Rocket Booster for the Energia rocket and, equipped with a second stage, as a stand-alone rocket.
Zenits are launched from Russia's Baikonur Cosmodrome in Kazakhstan, and by the Sea Launch organization's floating launch platform in the Pacific Ocean.
Since the Zenit is not built in Russia, it is planned to be replaced in that service by the new and yet unflown Angara rocket, although Russia does still use the Zenit.

 Pravda.RU:Defense Ministry satellite successfully launched
The rocket was initially developed for the rapid deployment and replenishment of Russian satellite group and manned spaceships.
After further development, the rocket's first stage was used as a booster for the Energia rocket carrier and successfully functioned in two launches.
Presently, the rocket is periodically used to launch satellites for Russia and Ukraine.

The sounding rocket zenith was a single-step rocket with a length of 5.6 meters, a diameter of 0.42 meters and a takeoff weight of 610 kilograms.
This rocket, which was propelled by solid-propellant engine, which supplied a thrust of 45kN in the starting phase and in the further flight phase of 22kN, could carry a pay load of 25 kilograms in 210 kilometers height or a pay load of 130 kilograms at a value of 115 kilometers.
For example the site I got the Isp for the Zenit rocket only states it in seconds,[7], now we can assume the source was from the Ukraine and it should be metric, but that is not a guarantee.

With eight Zenit booster rockets and an Energia-M core as an upper stage, the "Vulkan" (which was interestingly the same name of another Soviet heavy lift rocket that was cancelled years earlier) or "Hercules" configuration could have launched a stunning 175 tonnes into orbit.
The Energia rocket only flew twice, the first on May 15 1987, with the UKSS military payload, and the second on November 15 1988, with the Buran Shuttle.

Rocket bodies can receive a little kick during insertion of the payload into orbit and can start to tumble around one or more axes.
Measuring the time interval during which the rocket has flashed some tens of times can, after dividing this total time by the number of flash periods, give a good approximation for the true rotation period.
Immediately after the launch, most flash periods of rocket stages are of the order of a few seconds.

Russian experts said two weeks ago that a malfunction in the Russian-built control system of the Ukrainian-built rocket, which was carrying 12 U.S. satellites, caused the explosion that destroyed the rocket and the payload minutes after launch.
Horbulin, the control system of the Zenit II had a fatal design flaw that did not allow it to recognize a malfunction in the system's operation, which it mistook for a malfunction in the engine.
The rocket, which was carrying the largest payload of satellites ever carried by one rocket, went down near the Baikonur Cosmodrome in Kazakstan on September 9, five minutes after launch, when the second-stage booster rocket shut down.
