Notable examples are the Luna 16 and Luna 17 missions in 1970. All Protons are built at Khrunichev State Research and Production Space Center, and are then launched from Baikonur Cosmodrome . With the recent consolidation of the Russian space enterprises, Khrunichev has direct oversight and control of up to 70% of all Proton manufacturing from suppliers to manufacturers. More recently, however, the Mars 96 mission failed during a Proton launch in November 1996.In the mid-1970s, the Proton-K/D variant successfully carried several Venus missions into space. More problems with a Briz-M caused a partial failure of a December 2012 mission, although the satellite was able to move into its intended orbit. Proton did not complete its State Trials until 1977, at which point it was judged to have a higher than 90% reliability. Proton-K. Proton-K Blok-D (Zond L1) Proton-K Blok-D-1 (Granat) [ILS] similar: Proton-K Blok-D, Proton-K Blok-D-2 . Future US, Inc. 11 West 42nd Street, 15th Floor,
Proton (rocket family) rocket family. Proton-K/D rockets also launched several Luna missions. A workhorse since 1965, recent versions of the Proton-M have been plagued with failures.
The expendable launch vehicle is commonly used to launch commercial and Russian government satellites. Proton rockets have successfully lobbed other spacecraft to Venus and Mars, and parts of the Russian Salyut space station.Rockets are constructed at the Khrunichev State Research and Production Space Center plant in Moscow and launched from the Baikonur Cosmodrome in Kazakhstan.The Proton was originally conceived as an intercontinental ballistic missile that was called the UR-500, but its purpose changed to launching space payloads during development, In the late 1960s and early 1970s, several missions to the moon and Mars, launched on Proton-K/D rockets, ended in launch failures.
A Proton rocket also launched the core module of the Soviet Union's The Proton rocket line expanded to commercial business in the 1990s, with its first contract for the Inmarsat communications satellite in 1993; its first commercial payload was launched in 1996, according to In its Briz-M launch configuration, the Proton has a restartable upper stage and works with all major commercial spacecraft platforms, according to Since 2010, Protons have launched dozens of communications and navigation satellites, with a few failures along the way – mainly in Briz-M upper stages.
As of mid-2018, the rocket line has launched more than 400 times, with most of those launches being successful. Proton initially started its life as a \"super heavy ICBM.\" It was designed to launch a 100-megaton (or larger) thermonuclear weapon over a distance of 13,000 km.
Modern versions of the launch system are still in use as of 2019, making it one of the most successful heavy boosters in the history of spaceflight.
On October 21, another Ekspress satellite was left in a useless orbit when the Briz stage cut off 24 seconds too early.Khrunichev has initiated development of a set of phase IV enhancements in order to keep pace with market demands and the mass growth trends of commercial satellites. Modern versions of the launch system are still in use as of 2019, making it one of the most successful heavy boosters in the history of spaceflight.

Proton-K Blok-DM-2 . This included Veneras 9 and 10, whose lander components arrived safely on the surface in 1975, and Veneras 13 and 14, whose landers touched down in 1981. It is still in use as of 2018.
