"Russia Scraps Test Launch of New Heavy-Lift Space Rocket"

Russia aborted the test launch of its new heavy-lift Angara-A5 rocket from the Vostochny space launch facility due to a flaw in the oxidizer tank pressurization system. The next launch attempt is scheduled for Wednesday. The Angara-A5 rocket is part of the new Angara family of rockets developed to replace the Soviet-designed Proton rockets, and the Vostochny spaceport is being developed as the facility of choice for Angara launches.
