Associated Launch Vehicles
  • Proton-K/D Russian orbital launch vehicle. This four stage version of the Proton was originally designed to send manned circumlunar spacecraft into translunar trajectory. Guidance to the Block D stage must be supplied by spacecraft. The design was proposed on 8 September 1965 by Korolev as an alternate to Chelomei's LK-1 circumlunar mission. It combined the Proton 8K82K booster for the LK-1 with the N1 lunar Block D stage to boost a stripped-down Soyuz 7K-L1 spacecraft around the moon. The Korolev design was selected, and first flight came on 10 March 1967. The crash lunar program led to a poor launch record. Following a protracted ten year test period, the booster finally reached a level of launch reliability comparable to that of other world launch vehicles. More...
  • Proton-K Russian orbital launch vehicle. Development of a three-stage version of the UR-500 was authorised in the decree of 3 August 1964. Decrees of 12 October and 11 November 1964 authorised development of the Almaz manned military space station and the manned circumlunar spacecraft LK-1 as payloads for the UR-500K. Remarkably, due to continuing failures, the 8K82K did not satisfactorily complete its state trials until its 61st launch (Salyut 6 / serial number 29501 / 29 September 1977). Thereafter it reached a level of launch reliability comparable to that of other world launch vehicles. More...
  • Proton-K/DM Russian orbital launch vehicle. The original four stage Proton / Block D configuration was used until 1976, at which time it was replaced by a modernised version equipped with N2O4/UDMH verniers for precise placement of payloads in geosynchronous orbit and its own self-contained guidance unit. This was accepted into military service in 1978 with the first Raduga launch. The stage was first developed for launch of gesynchronous military communications and early warning satellites (Raduga, Ekran, Gorizont, Potok, SPRN). Its later versions continue in use for launch of MEO and geosynchronous comsats, and was Russia's most successful commercial launcher. More...
  • Proton-K/D-1 Russian orbital launch vehicle. This derivative of the original four stage Block D / 11S824 version of the Proton was used from 1978 to launch Lavochkin OKB planetary probes (Mars, Venera) and high earth orbit astronomical observatories (Astron, Granat). Guidance to the Block D-1 stage must be supplied by spacecraft. Equipped with N2O4/UDMH verniers for precise placement of payloads in high orbits or planetary trajectories. More...
  • Proton-K/DM-2 Russian orbital launch vehicle. This improved four stage version uses the Block DM-2 / 11S861 fourth stage, which has its own guidance unit. This reduces payload but does not require the spacecraft's guidance system to provide steering commands to booster. Replaced the original Block DM / 11S86 version from 1982 to 1995. Used for launch of Glonass navigation satellites into medium earth orbit; and launch of Luch, Ekran-M, Potok, Raduga, Gorizont, Raduga-1, Elektro, and Gals communications satellites into geosynchronous orbit. Commercial version with Saab payload adapter-seperation system for Western payloads was dubbed 'Block DM1'. More...
  • Proton-K/DM-2M This four stage version uses the Block DM-2M / 11S861-01 upper stage, which has its own self-contained guidance unit. This reduces payload but does not require the spacecraft's guidance system to provide steering commands to booster. Used for launches of Russian geosynchronous satellites from 1994 on. More...
  • Proton-K/17S40 Russian orbital launch vehicle. Version of Proton using Block DM-5 / 17S40 fourth stage. This stage has a new payload adapter for use with heavier paylods launched into sub-synchronous orbits. Used for launch of Arkon reconnaisance satellite. More...
  • Proton/Briz K/M Earlier 8K82K model Proton, but Briz M storable propellant upper stage replaced the Block D cyrogenic stage. More...
  • Proton/Briz M Improved Proton orbital launch vehicle. Improvements in lower stages to reduce structural mass, increase thrust, and fully utilize propellants (reducing release of toxic chemicals in stage impact areas). Briz M storable propellant upper stage replaces Block D cyrogenic stage. More...
  • Proton-M/DM-2 Russian orbital launch vehicle. Improved Proton-M stages, mated to the older 11S861 upper stage for certain payloads. More...
  • Proton-K/DM-2M DM3 Russian orbital launch vehicle. Version of the 11S861-01 with Saab payload adapter-seperation system for insertion of Hughes HS-601 bus spacecraft into geosynchronous orbit. More...

Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.

Baikonur LC81/24 Chronology


1967 November 22 - . 19:07 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/D. LV Configuration: Proton-K/D 230-01. FAILURE: Second stage - 1 x RD-0210 failure, shutoff of stage 4 seconds after ignition. Launcher crashed downrange.. Failed Stage: 2.
  • Soyuz 7K-L1 s/n 5L - . Payload: Soyuz 7K-L1 s/n 5L. Mass: 5,390 kg (11,880 lb). Nation: USSR. Related Persons: Glushko; Chelomei; Mishin; Leonov. Agency: RVSN. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft: Soyuz 7K-L1. Decay Date: 1967-11-21 . COSPAR: F671122A. The launch takes place at 00:07 local time (22:07 on 22 November Moscow time). Glushko, Chelomei, and Kamanin observe the launch from an observation point in -5 deg C weather. Three to four seconds after second stage ignition, the SAS pulls the spacecraft away from the booster. Telemetry shows that engine number 4 of stage 2 never ignited, and after 3.9 seconds the remaining three engines were shut dwon by the SBN (Booster Safety System) and the SAS abort tower fired. The capsule's radio beacon was detected and the spacecraft was found 80 km southwest of Dzhezkazgan, 285 km down range. The Proton problems are maddening. Over 100 rocket launches have used engines from this factory, with no previous failure. Of ten of the last launches under Mishin's direction (6 Soyuz and 4 L1) only two have went well - an 80% failure rate! Mishin is totally without luck. Kamanin and Leonov take an An-12 to see the L1 at its landing point. Leonov wants to see proof that the cosmonauts would be saved in any conditions. The capsule landed in -17 deg C and 12 m/s winds. The parachute pulled the capsule along the ground for 550 m, and the soft landing rockets fired somewhere above the 1.2 m design height. After safing of the APO self-destruct package, the capsule is lifted to an airfield by a Mi-4.

1968 April 22 - . 23:01 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/D. LV Configuration: Proton-K/D 232-01. FAILURE: Second stage shut-off prematurely due to short-circuit in Zond control system.. Failed Stage: 2.
  • Soyuz 7K-L1 s/n 7L - . Payload: Soyuz 7K-L1 s/n 7L. Mass: 5,390 kg (11,880 lb). Nation: USSR. Agency: RVSN. Program: Lunar L1. Class: Manned. Type: Manned spacecraft. Spacecraft: Soyuz 7K-L1. Decay Date: 1968-04-22 . COSPAR: F680422A. L1 launch attempt, lift-off at 02:00 local time. The spacecraft was to separate at 589 seconds into the flight. Instead at 260 seconds, a short circuit in the malfunction detection system incorrectly indicated a launch vehicle failure. This in turn triggered the SAS abort system. The SAS shut down the good stage and separated the spacecraft from the booster. The capsule landed safely 520 km downrange from the launch site. This was the third such abort, which if nothing else proved the reliability of the SAS - all of the spacecraft landed safely.

1968 November 16 - . 11:40 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K. LV Configuration: Proton-K 236-01.

Summary: First launch of the Proton three-stage variant. The satellite studied the nature of high and ultra-high energy cosmic rays and their interaction with atomic nuclei. Scientific payload 12,500 kg; operated for 100 days in orbit. .

1969 February 19 - . 06:48 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/D. LV Configuration: Proton-K/D 239-01. FAILURE: First-stage engine failure caused the rocket to crash 15 km from the pad.. Failed Stage: 1.
  • Ye-8 s/n 201 + Lunokhod s/n 201 - first stage malfunction - . Payload: Ye-8 s/n 201 / 8EL No. 201. Mass: 5,600 kg (12,300 lb). Nation: USSR. Agency: RVSN. Program: Luna. Class: Moon. Type: Lunar probe. Spacecraft: Luna Ye-8. Decay Date: 1969-02-19 . COSPAR: F690219A. Attempted launch of a Ye-8 with a Lunokhod lunar rover. Evidently coordinate in some way with the N1 launch two days later. A first-stage booster engine failure causes the rocket to crash 15 km from the pad after a lift-off at 09:48 local time. Kamanin meanwhile has the Hong Kong flu.

1969 April 2 - . 10:33 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/D. LV Configuration: Proton-K/D 233-01. FAILURE: First stage - 1 x RD-253 fire beginning at T+ 0.02 sec, rocket crashed near pad.. Failed Stage: 1.
  • M-69 s/n 522 - . Payload: M-69 s/n 522. Nation: USSR. Agency: RVSN. Program: Mars. Class: Mars. Type: Mars probe. Spacecraft: Mars M-69. Decay Date: 1969-04-02 . COSPAR: F690402A. Mars probe intended to enter Martian orbit and comprehensively photograph Mars, together with a landing probe. Further Mars launches during the 1969 launch window were cancelled when this attempt resulted in a major accident, which almost wiped out all of the leaders of the space industry. The Proton rocket lifted off, but one engine failed. The vehicle flew at an altitude of 50 m horizontally, finally exploding only a short distance from the launch pad, spraying the whole complex with poisonous propellants that were quickly spread by the wind. Everyone took off in their autos to escape, but which direction to go? Finally it was decided that the launch point was the safest, but this proved to be even more dangerous - the second stage was still intact and liable to explode. The contamination was so bad that there was no way to clean up - the only possibility was just to wait for rain to wash it away. This didn't happen until the Mars launch window was closed, so the first such probe was not put into space until 1971. This accident also severely damaged plans to divert attention from America's Apollo programme during the rest of 1969. 10-12 UR-500K launches had been intended to land on the moon lunar soil return and rover robots to supplement the N1 launches.

1969 June 14 - . 04:00 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/D. LV Configuration: Proton-K/D 238-01. FAILURE: Block D upper stage did not fire and payload did not attain earth orbit,. Failed Stage: 4.
  • Ye-8-5 s/n 402 - . Payload: Ye-8-5 s/n 402. Mass: 5,600 kg (12,300 lb). Nation: USSR. Agency: RVSN. Program: Lunar L1; Luna. Class: Moon. Type: Lunar probe. Spacecraft: Luna Ye-8-5. Decay Date: 1969-06-04 . COSPAR: F690614A. Another attempt to launch a Ye-8-5 to return lunar soil to the earth, 'scooping', the Americans' impending Apollo 11 mission. Yet another UR-500K launch failure. This time the UR-500K booster functioned perfectly, but the Block D upper stage did not fire, and the payload did not even attain earth orbit. Every UR-500K launch is costing the Soviet state 100 million roubles. This failure pretty much ended the chances for the Russians to trump the American moon landing. Tass yesterday began running stories to prepare the masses for the upcoming Apollo 11 triumph. The party line is that the Soviet Union is not about to risks the lives of its cosmonauts on flights to the moon, when automated probes can safely retrieve soil from the moon for study on earth.

Perigee: 180 km (110 mi). Inclination: 51.4000 deg. Period: 88.50 min. First manned space station. Salyut 1 included a number of military experiments, including the OD-4 optical visual ranger, the Orion ultraviolet instrument for characterising rocket plumes, and the highly classified Svinets radiometer. Primary objectives included photography of the earth, spectrographs of the earth's horizon, experiments with intense gamma rays, and studying manual methods for station orientation.

    At 05:20 the State Commission and their guests arrive at the Area 95 observation point to view the launch. The booster takes off on schedule at 06:40 in light rain and 60 km/hr wind. The tracking station reports good orbital insertion, separation from the third stage, and antennae and solar panel deployment. But the cover of the scientific equipment bay does not separate. This will mean that many experiments cannot be accomplished. It is decided to launch the crew to the station anyway, since the station is otherwise functioning normally. The cosmonauts go to the baths in the evening. Additional Details: here....


1971 May 19 - . 16:22 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/D. LV Configuration: Proton-K/D 255-01.
  • Mars 2 - . Payload: M-71 s/n 171. Mass: 4,650 kg (10,250 lb). Nation: USSR. Agency: MOM. Program: Mars. Class: Mars. Type: Mars probe. Spacecraft: Mars M-71. USAF Sat Cat: 5234 .

Mars probe intended to conduct of a series of scientific investigations of the planet Mars and the space around it. Parameters are for Mars orbit. Mid-course corrections were made on 17 June and 20 November. Mars 2 released the descent module (1971-045D) 4.5 hours before reaching Mars on 27 November 1971. The descent system malfunctioned and the lander crashed at 45 deg S, 302 deg W, delivering the Soviet Union coat of arms to the surface. Meanwhile, the orbiter engine performed a burn to put the spacecraft into a 1380 x 24,940 km, 18 hour orbit about Mars with an inclination of 48.9 degrees. Scientific instruments were generally turned on for about 30 minutes near periapsis. Data was sent back for many months. It was announced that Mars 2 and 3 had completed their missions by 22 August 1972. On-orbit dry mass: 2265 kg. Had the lander survived, data would have been relayed to the earth via the orbiter.

After separation of the lander, the orbiter spacecraft entered Venus orbit and acted as a communications relay for the lander and explored cloud layers and atmospheric parameters. On October 20, 1975, the Descent Craft was separated from the Orbiter, and landing was made with the sun near zenith at 05:13 GMT on October 22. The Descent Craft included a system of circulating fluid to distribute the heat load. This system, plus precooling prior to entry, permitted operation of the spacecraft for 53 min after landing. The landing was about 2,200 km from the Venera 10 landing site. Preliminary results indicated: (A) clouds 30-40 km thick with bases at 30-35 km altitude, (B) atmospheric constituents including HCl, HF, Br, and I, (C) surface pressure about 90 (earth) atmospheres, (D) surface temperature 485 deg C, (E) light levels comparable to those at earth midlatitudes on a cloudy summer day, and (F) successful TV photography showing shadows, no apparent dust in the air, and a variety of 30-40 cm rocks which were not eroded. Venera 9 and 10 were the first probes to send back black and white pictures from the Venusian surface. They were supposed to make 360 degree panoramic shots, but on both landers one of two camera covers failed to come off, restricting their field of view to 180 degrees. Parameters are for Venus orbit.

Launch of mission LVI-1 came at 04:00 on 15 December. At 176 seconds the ADU escape tower separated from the LVI. Once the final stage had shut down in orbit, by command from the launch vehicle sequencer, the VA 009A (also given as 009P) and its TDU separated from the LVI. Two seconds later VA 009 (or 009L) was ejected. Fifteen minutes after launch all systems of the both VA capsules were in operation. The guidance system detected the direction of flight and oriented each spacecraft for retro-fire, and the pair began the return to earth after less than one revolution. At an external atmospheric pressure of 165 mm (10 km altitude) the NO section jettisoned, the three-cupola drogue parachute ejected, and the antennae and altimeter were deployed. The Komara landing radio beacon (installed on the landing section of the parachute) was activated when the spacecraft was 1.0 to 1.5 m above the ground - which occurred at the same moment on both 009 and 009A. The Kaktus special system tripped the soft landing PRSP (parachute landing propulsion system). The soft landing was accomplished with higher accuracy than Soyuz, both capsules being recovered at 44 deg N, 73 deg E, on December 15, 1976 3:00 GMT. The flights were officially given the designations Cosmos 881 (VA 009A) and Cosmos 882 (VA 009). US intelligence believed them to be tests of recoverable manned spaceplane prototypes.

Given the on-pad explosion of the LVI-2 launch attempt, plans to crew the upper VA re-entry capsule in the next test was abandoned. LVI-3 (VA's 102P and 102L / Cosmos 997 and Cosmos 998) was launched unmanned four months behind the original schedule. Both capsules were recovered after one orbit. One source indicates that one of the capsules was 009P, on its third launch and second flight to orbit. This was said to have demonstrated the multiple re-entry capability of the heat shield and the first planned reuse of a spacecraft (Gemini 2 was refurbished and reflown as MOL-1 in the 1960's, but was not designed for that purpose).

  • Venera 12 - . Payload: 4V-1 s/n 361. Mass: 4,715 kg (10,394 lb). Nation: USSR. Agency: MOM. Program: Venera. Class: Venus. Type: Venus probe. Spacecraft: Venera 4V-1. USAF Sat Cat: 11025 . COSPAR: 1978-086A. Venera 12 was part of a two-spacecraft mission to study Venus and the interplanetary medium. Each of the two spacecraft, Venera 11 and Venera 12, consisted of a flight platform and a lander probe. Identical instruments were carried on both spacecraft. Venera 12 was launched into a 177 x 205 km, 51.5 degree inclination Earth orbit from which it was propelled into a 3.5 month Venus transfer orbit which involved two mid-course corrections, on 21 September and 14 December. After ejection of the lander probe on 19 December, two days before encounter, the flight platform continued on past Venus in a heliocentric orbit. Near encounter with Venus occurred on December 21, 1978, at approximately 34,000 km altitude. The flight platform acted as a data relay for the descent craft for 110 minutes until it flew out of range and returned to its own measurements on interplanetary space. The Venera 12 descent craft entered the Venus atmosphere at 11.2 km/sec two days after separation from the flight bus. During the descent, it employed aerodynamic braking followed by parachute braking and ending with atmospheric braking. It made a soft landing on the surface at 06:30 Moscow time on 21 December after a descent time of approximately 1 hour. The touchdown speed was 7-8 m/s.

    Both Venera 11 and 12 landers failed to return colour television views of the surface and perform soil analysis experiments. All of the camera protective covers failed to eject after landing (the cause was not established) The soil drilling experiment was apparently damaged by a leak in the soil collection device, the interior of which was exposed to the high Venusian atmospheric pressure. The leak had probably formed during the descent phase because the lander was less aerodynamically stable than had been thought. Therefore the landing gear of the following two landers (Venera-13/14) were equipped with tooth-shaped stabilisers.

    Results reported included evidence of lightning and thunder, a high Ar36/Ar40 ratio, and the discovery of carbon monoxide at low altitudes.

    The Venera-12 flyby bus continued in solar orbit and successfully used its Soviet-French ultraviolet spectrometer to study Comet Bradfield on 13 February 1980 (one year and two months after its Venus encounter). At that time the spacecraft was 190,373,790 km from Earth.

On 20 April 1979 LVI-4 VA (VA s/n 103 and s/n 008) was awaiting launch. The booster ignited, but then shut down on the pad. This triggered the launch escape system, which pulled the top capsule away from the booster. The parachute system failed and the capsule crashed to the ground. The lower capsule remained in the rocket. The top capsule was to have been manned, but the inability to demonstrate two consecutive failure-free launches of the Proton/TKS-VA combination made that (luckily) impossible.

The Proton launch vehicle that shut down on the original LVI-4 launch attempt was undamaged, and just a month later, with a switch of payload, LVI-4 was orbited as Cosmos 1100 and 1101. The pair launched were the 102P/102L twins from LVI-3. One capsule failed when the automatic system suffered an electrical distribution failure and it did not land correctly, spending two orbits in space, while the other landed as planned after one orbit. The launch again successfully demonstrated the reusability of the VA capsule. Plans to launch the upper capsule manned were scrubbed due to the inability to get two consecutive failure-free launches of the Proton/TKS-VA.
