Russia Launches Angara-A5 Heavy Lift Rocket in Landmark Space Program Milestone
Baikonur cosmodrome,Kazakhstan – Russia successfully launched its new-generation Angara-A5 heavy-lift rocket on December 11,2023,marking a pivotal moment in the nation’s space program and reducing its reliance on the Baikonur Cosmodrome,currently leased from Kazakhstan. The launch,conducted from the Vostochny Cosmodrome in the Russian Far East,represents a significant step towards establishing a fully autonomous Russian space launch capability and opens new avenues for both commercial and national security space missions. https://tass.com/defense-industry/1723493
The Angara family of rockets, developed by the Khrunichev State Research and Production Space Center, is designed to replace the aging Proton and Rokot launch vehicles. Unlike its predecessors, which rely on toxic hypergolic propellants, the Angara utilizes environmentally amiable liquid oxygen and kerosene, aligning with modern space launch practices. This shift not only reduces environmental impact but also simplifies launch operations and lowers costs.
A New Era for Russian Space Launches
For decades, Russia has been heavily dependent on the Baikonur Cosmodrome, a legacy of the Soviet space program, located in Kazakhstan. While a crucial facility, this reliance has presented geopolitical challenges and financial burdens, as Russia pays Kazakhstan for its use. The development and accomplished launch of the Angara-A5 are central to Russia’s strategy of establishing a sovereign launch capability from its own territory, specifically from Vostochny Cosmodrome. https://spaceflightnow.com/2023/12/11/angara-a5-rocket-launches-on-second-test-flight-from-vostochny/
vostochny Cosmodrome, located in the Amur Oblast region, has been under development since 2010. Its strategic location offers advantages for launching missions into a variety of orbits, notably those requiring high inclinations, crucial for servicing polar regions and supporting Earth observation satellites. The Angara-A5’s successful launch from vostochny demonstrates the cosmodrome’s operational readiness and its potential to become a major hub for Russian space activities.
Technical Specifications and Capabilities of the Angara-A5
The Angara-A5 is a two-stage rocket, standing approximately 69 meters (226 feet) tall. It boasts a payload capacity of up to 27.6 tonnes to low earth orbit (LEO) and 13.5 tonnes to geostationary transfer orbit (GTO). This capability places it in direct competition with other heavy-lift launch vehicles like SpaceX’s Falcon Heavy and the United Launch Alliance’s Delta IV Heavy. https://www.esa.int/Applications/Human_Spaceflight/Angara_rocket_family
Key features of the Angara-A5 include:
* Universal Rocket Module (URM-1): The frist stage consists of four URM-1 engines, providing the bulk of the thrust for liftoff. These engines are designed for high reliability and efficiency.
* URM-2 Second Stage: The second stage utilizes a single URM-2 engine, optimized for vacuum operation to efficiently deliver payloads to their intended orbits.
* Modular Design: The Angara family is built on a modular design philosophy, allowing for different configurations to be created based on mission requirements. this adaptability reduces development costs and streamlines production.
* Environmentally Friendly Propellants: The use of liquid oxygen and kerosene minimizes environmental impact compared to older rockets using toxic propellants.
The Mission Payload and Future Plans
The December 11th launch carried a mock payload, a mass simulator, designed to test the rocket’s systems and performance during flight. This was the second test flight of the Angara-A5, following a first attempt in 2014 which experienced some anomalies. The successful completion of this second test flight validates the design and paves the way for operational missions.
Looking ahead, russia plans to utilize the Angara-A5 for a variety of purposes, including:
* Launching components for the Russian Orbital Service Station (ROSS): Russia intends to build its own space station, ROSS, as a successor to the International Space Station (ISS). The Angara-A5 will be crucial for delivering modules and supplies to the new station. https://space.skyrocket.de/doc_ssta/ross.htm
* Supporting national security missions: the Angara-A5’s increased payload capacity and independent launch capability enhance Russia’s ability to
