Range Safety
In rocketry, range safety or flight safety is ensured by monitoring the flight paths of missiles and launch vehicles, and enforcing strict guidelines for rocket construction and ground-based operations. Various measures are implemented to protect nearby people, buildings and infrastructure from the dangers of a rocket launch. Governments maintain many regulations on launch vehicles and associated ground systems, prescribing the procedures that need to be followed by any entity aiming to launch into space. Areas in which one or more spaceports are operated, or ranges, issue out closely guarded exclusion zones for air and sea traffic prior to launch, and close off certain areas to the public. Contingency procedures are performed if a vehicle malfunctions or veers off course mid-flight. Sometimes, a range safety officer (RSO) commands the flight or mission to end by sending a signal to the flight termination system (FTS) aboard the rocket. This takes measures to eliminate any mean ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Venera 4
Venera 4 (), also designated 4V-1 No.310, was a probe in the Soviet Venera program for the exploration of Venus. The probe comprised a lander, designed to enter the Venusian atmosphere and parachute to the surface, and a carrier/ flyby spacecraft, which carried the lander to Venus and served as a communications relay for it. In 1967, it was the first successful probe to perform in-place analysis of the environment of another planet. Venera 4 provided the first chemical analysis of the Venusian atmosphere, showing it to be primarily carbon dioxide with a few percents of nitrogen and below one percent of oxygen and water vapors. While entering the atmosphere it became the first spacecraft to survive entry into another planet's atmosphere. The station detected a weak magnetic field and no radiation field. The outer atmospheric layer contained very little hydrogen and no atomic oxygen. The probe sent the first direct measurements proving that Venus was extremely hot, that ...

Kosmos 96
Kosmos 96 ( meaning ''Cosmos 96''), or 3MV-4 No.6, was a Soviet spacecraft intended to explore Venus. A 3MV-4 spacecraft launched as part of the Venera programme, Kosmos 96 was to have made a flyby of Venus. However, due to a launch failure, it did not depart low Earth orbit. Its re-entry into Earth's atmosphere is often speculated as the cause of the Kecksburg UFO incident. Mission This was the third and last spacecraft prepared for a Venus encounter. The 3MV-4 No.6 spacecraft was originally built for a mission to Mars, with launch scheduled for late 1964. After it was not launched by the end of its launch window, the spacecraft was repurposed, along with two other spacecraft which were launched as Venera 2 and Venera 3, to explore Venus. Instruments The eight scientific instruments were: * Three-component magnetometer * An imaging system * A solar X-radiation detector * Cosmic ray gas-discharge counters * Piezoelectric detectors * Ion traps * A photon Geiger counter * Cosm ...

Venera 3
Venera 3 ( meaning ''Venus 3'') was a Venera program space probe that was built and launched by the Soviet Union to explore the surface of Venus. It was launched on 16 November 1965 at 04:19 UTC from Baikonur, Kazakhstan, USSR. The probe comprised an entry probe, designed to enter the Venus atmosphere and parachute to the surface, and a carrier/flyby spacecraft, which carried the entry probe to Venus and also served as a communications relay for the entry probe. History In 1965, the Central Committee, frustrated at the poor track record of Sergei Korolev's OKB-1 design bureau, reassigned the planetary probe program to the Lavochkin Bureau. In over two dozen attempts dating back to 1958, Luna 2 and Luna 3 were the only probes to complete all of their mission objectives. In the meantime, the United States had succeeded with the Mariner 2 Venus probe and Mariner 4 Mars probe, and after a long string of lunar probe failures, Ranger 6 successfully impacted on the Moon (with a fai ...

Venera 2
Venera 2 ( meaning ''Venus 2''), also known as 3MV-4 No.4 was a Soviet spacecraft intended to explore Venus. A 3MV-4 spacecraft launched as part of the Venera programme, it failed to return data after flying past Venus. Venera 2 was launched by a Molniya carrier rocket, flying from Site 31/6 at the Baikonur Cosmodrome. The launch occurred at 05:02 UTC on 12 November 1965, with the first three stages placing the spacecraft and Blok-L upper stage into a low Earth parking orbit before the Blok-L fired to propel Venera 2 into heliocentric orbit bound for Venus, with perihelion of 0.716 AU, aphelion of 1.197 AU, eccentricity Eccentricity or eccentric may refer to: * Eccentricity (behavior), odd behavior on the part of a person, as opposed to being "normal" Mathematics, science and technology Mathematics * Off-Centre (geometry), center, in geometry * Eccentricity (g ... of 0.252, inclination of 4.29 degrees and orbital period of 341 days.

Zond 1
Zond 1 was a spacecraft of the Soviet Zond program. It was the second Soviet research spacecraft to reach Venus, although communications had failed by that time. It carried a spherical landing capsule, containing experiments for chemical analysis of the atmosphere, gamma-ray measurements of surface rocks, a photometer, temperature and pressure gauges, and a motion/rocking sensor in case it landed in water. An experimental Ion thruster was also carried for evaluation. History At least three previous Soviet planetary probes had been lost due to malfunctions of the ullage rockets (BOZ) on the Blok L stage, but an investigation found that the problem was easily resolved. The spacecraft, a ''Venera 3MV-1'', was launched on April 2, 1964, from Tyuratam and this time the launch vehicle performed flawlessly. During the cruise phase, a slow leak from a cracked sensor window caused the electronics compartment to lose air pressure. This was a serious problem as Soviet electronics reli ...

Kosmos 27
Kosmos 27 ( meaning ''Cosmos 27''), also known as Zond 3MV-1 No.3 was a space mission intended as a Venus impact probe. The spacecraft was launched by a Molniya 8K78 carrier rocket from Baikonur. The Blok L stage and probe reached Earth orbit successfully, but the attitude control system failed to operate. Launch Kosmos 27 was launched at 03:24:43 GMT on 27 March 1964, atop a Molniya 8K78 s/n T15000-27 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome The Baikonur Cosmodrome is a spaceport operated by Russia within Kazakhstan. Located in the Kazakh city of Baikonur, it is the largest operational space launch facility in terms of area. All Russian Human spaceflight, crewed spaceflights are l .... Spacecraft Kosmos 27 was a "third-generation" deep space planetary probes of the 3MV series of the Soviet Union. The Soviet engineers planned four types of the 3MV, the 3MV-1 (for Venus impact), 3MV-2 (for Venus flyby), 3MV-3 (for Mars impact), and 3MV-4 (fo ...

Molniya-M
The Molniya-M (, GRAU index: 8K78M) was a Soviet and Russian launch vehicle derived from the R-7 Semyorka Intercontinental ballistic missile (ICBM). The original 8K78 booster had been the product of a rushed development program and its launch record was no better than the 8K72 Luna booster of 1958–1960. As 1962 ended, there had been 12 launches of 8K78s, ten of which failed (five Block L failures, four Block I failures, and one failure caused by the Block A core stage). The two successful launches had had their probes ( Venera 1 and Mars 1) fail en route to their respective planetary targets. As such, work began at the Korolev Bureau to improve the basic 8K78 vehicle. The core and strap-ons received the up-rated 8D74M engines and the Kosberg Bureau completely redesigned the Block I stage. The Block L engine was also slightly enhanced. The first six 8K78Ms built used RD-0108 engines in the Block I stage, which was also used in the two crewed Voskhod boosters, all subseque ...

Venera 2MV-2 No
The Venera (, 'Venus') program was a series of space probes developed by the Soviet Union between 1961 and 1984 to gather information about the planet Venus. Thirteen probes successfully entered the Venusian atmosphere, including the two Venera-Halley probes. Ten of those successfully landed on the surface of the planet. Due to the extreme conditions, the probes could only survive for a short period on the surface, from 23 minutes to two hours. The ''Venera'' program established a number of precedents in space exploration, among them being the first human-made devices to enter the atmosphere of another planet (Venera 3 on 1 March 1966), the first to make a soft landing on another planet ( Venera 7 on 15 December 1970), the first to return images from another planet's surface (Venera 9 on 8 June 1975), the first to record sounds on another planet (Venera 13 on 30 October 1981), and the first to perform high-resolution radar mapping scans ( Venera 15 on 2 June 1983).
