Russia successfully test launches heavy lift space rocket after long hiatus Russia on Monday successfully test launched its heavy lift Angara A5 space rocket after a six-year hiatus in a project President Vladimir Putin describes as having huge significance for national security. First test-launched in 2014, it is being developed to replace the Proton M as Russia's heavy lift rocket, capable of carrying payloads bigger than 20 tonnes into orbit. A launch pad for the new rocket is due to open in 2021.
