COMPETITION: Russia’s Proton rocket, which predates Apollo, will finally stop flying.

The decision will bring down the curtain on one of the longest-used and most versatile rockets in world history. As the United States developed the space shuttle in the 1970s and began flying it in the 1980s, the Russian space agency saw the opportunity to commercialize the Proton rocket, and by the end of the 1990s, the booster became a major moneymaker for the Russian space industry. With a capacity of 22.8 tons to low-Earth orbit, it became a dominant player in the commercial market for heavier satellites.

It remained so during much of the 2000s, but as Ars has previously reported, the lack of technical oversight began manifesting itself in an increasing rate of failures. At the end of 2010, one Proton plunged into the ocean because too much propellant had been mistakenly loaded into its upper stage. In 2013, another vehicle performed a fiery dance seconds after liftoff because flight control sensors were hammered into the rocket’s compartment upside down.

More failures have followed in recent years. These problems, combined with the rapid rise of low-cost alternatives such as SpaceX’s Falcon 9 rocket, have caused the number of Proton launches in a given year to dwindle from eight or so to just one or two.

The Russians historically are good at this stuff, but the Angara isn’t scheduled to exit the develop stage before next year — at which point the BFR, SpaceX’s follow-on vehicle for the Falcon 9, is expected to begin full testing.
