Russia test-launches Angara A5 heavy lift space rocket

Russian military and space officials say the country has successfully test-launched its heavy lift Angara A5 space rocket for the second time

MOSCOW — Russia on Monday successfully test-launched its heavy lift Angara A5 space rocket for the second time, the country’s military and space officials said.

Its first successful test launch took place in 2014 and was hailed by Russian President Vladimir Putin as “a major achievement for our space rocket industry and for Russia in general.”

Angara A5 is designed to replace the Proton M heavy lift rocket, but its development and manufacturing has been plagued by delays and technical problems.

Roscosmos on Monday touted the increased environmental safety of the Angara rockets, as they “do not use aggressive and toxic propellants, significantly increasing environmental safety both in the areas adjacent to the launch complex and in the drop zones.”
