Russia to test-launch Angara heavy rocket from Vostochny spaceport on second attempt

The Angara test-launch from the Vostochny spaceport will commence flight development tests of the Amur rocket system that comprises the Angara carrier rocket and the spaceport’s infrastructure

MOSCOW, April 10. /TASS/. Russia will make a second attempt to test-launch an Angara-A5 heavy carrier rocket from the Vostochny spaceport on Wednesday after its aborted liftoff on April 9.

The successful launch will commence flight development tests for the Angara-A5 heavy rocket and its Orion booster from the Vostochny cosmodrome in the Russian Far East.

The Angara-A5 rocket was initially set to blast off from the Vostochny space center in the Amur Region at 12:00 p.m. Moscow time (9:00 a.m. GMT) on April 9. However, the liftoff was automatically canceled two minutes before the launch. Russia’s State Space Corporation Roscosmos Head Yury Borisov explained later that the technical malfunction had been caused by a failure in the pressurizing system of the central unit’s oxidizer tank. He said that the launch date had been tentatively rescheduled for April 10 but gave no exact timeframe.

In about 12 minutes after the liftoff, the rocket’s Orion booster with payload will separate from the Angara launch vehicle and continue delivering it into the designated orbit.

The upcoming launch will be the first for the Angara rocket from the Vostochny spaceport: previously, these launch vehicles blasted off only from the Plesetsk cosmodrome in northwestern Russia.

The first three launches of Angara heavy rockets from the Plesetsk spaceport took place on December 23, 2014, December 14, 2020 and December 27, 2021. The launch of the light Angara rocket took place on July 9, 2014 (the suborbital test flight), on April 29, 2022 (the orbital flight) and October 15, 2022 (the orbital flight).

The Angara test-launch from the Vostochny spaceport will commence flight development tests of the Amur rocket system that comprises the Angara carrier rocket and the spaceport’s infrastructure. The construction of infrastructure for the Angara rocket at the Vostochny cosmodrome began in 2019 and late last year the operational capacity of the technical compound and the launch pad was confirmed during the tests of the Angara-NZh, a full-size mockup of the Angara-A5 rocket. Technological solutions allow for launching all types of Angara rockets from one launch pad: from light to heavy carrier vehicles.

The first Angara-A5 flight version for the Vostochny spaceport was manufactured by the Omsk-based Polyot Production Association (a branch of the Khrunichev Center within Roscosmos). In December last year, the manufacturer sent the Angara-A5 carrier rocket by railways to the Vostochny spaceport where it arrived in early January. The rocket was put on the launch pad on March 26.

Angara family of carrier rockets

The Angara is a family of next-generation Russian space rockets. It consists of light, medium and heavy carrier rockets with a lifting capacity of up to 37.5 tons. The new family of rockets uses kerosene and liquid oxygen as environmentally friendly propellant components compared to the fuel of the Proton-M rocket, which Angara will replace in the future.

Aside from the baseline Angara-A5 rocket (a liftoff mass of about 773 tons and a carrying capacity of up to 24.5 tons into low near-Earth orbit), Russia is set to produce the Angara-A5M modification with the increased lifting capacity and the Angara-A5V launch vehicle with the first and second reusable stages and the third hydrogen-powered stage.

Russia intends to use the Angara family of carrier rockets to put automatic probes (for instance, the Spektr-UF orbital observatory) into near-Earth orbit, deliver some modules of its future Russian Orbital Station and crews to the orbital outpost aboard the next-generation spacecraft.

Angara carrier rocket cleared for test-launch from Vostochny spaceport

Russia’s state commission has cleared the Angara-A5 carrier rocket with the Orion booster for test-launch from the Vostochny cosmodrome, Roscosmos reported.

"Today the state commission has authorized the fueling and launch of the first Angara-A5 space rocket from the Vostochny cosmodrome," Roscosmos said in a statement.

According to the latest information, the launch of the Angara-A5 rocket from site 1A at the Vostochny spaceport is scheduled for 12:00 p.m. Moscow time (09:00 a.m. GMT) on April 10.
