Angara 1.2

The Angara 1.2 is a rocket launch vehicle developed by the Russian space agency, Roscosmos. It is part of the Angara family of rockets, which were designed to replace the aging Soyuz rockets and to provide Russia with a new generation of space launch vehicles. The Angara 1.2 is a medium-lift rocket capable of carrying payloads weighing up to 3,800 kg (8,400 lb) into low Earth orbit (LEO). In this article, we will discuss the history, development, and achievements of the Angara 1.2 rocket.

History:

The development of the Angara rocket family began in the early 1990s as a response to the need for a new generation of launch vehicles that could replace the Soviet-era rockets. The project was initially led by the Khrunichev State Research and Production Space Center, which was tasked with designing the new rockets. The first launch of the Angara rocket family took place in 2014, when the Angara 1.2 was launched from the Plesetsk Cosmodrome in northern Russia.

Development:

The Angara 1.2 rocket is a two-stage rocket that uses liquid oxygen and kerosene as propellants. The first stage of the rocket is powered by a single RD-191 engine, which is capable of generating 1,900 kN (430,000 lbf) of thrust. The second stage is powered by a single RD-0124A engine, which is capable of generating 297 kN (67,000 lbf) of thrust. The rocket is equipped with a payload fairing that can accommodate payloads measuring up to 3.8 meters (12 ft) in diameter.

The development of the Angara 1.2 rocket was a long and difficult process, as the project faced numerous technical and financial challenges. The rocket had to be designed from scratch, and the development team had to overcome a number of technical hurdles, such as developing a new type of fuel tank and creating a new guidance system. In addition, the project faced financial difficulties due to a lack of funding and delays in the construction of the rocket's launch site.

Cost:

The cost of developing the Angara 1.2 rocket is estimated to be around $1 billion. This includes the cost of designing and testing the rocket, as well as the cost of building the launch facilities. The cost of each launch of the Angara 1.2 rocket is estimated to be around $50 million.

Achievements:

The Angara 1.2 rocket has achieved a number of important milestones since its first launch in 2014. Some of the key achievements of the rocket include:

Successful launches: The Angara 1.2 has completed several successful launches since its first flight in 2014. These launches have demonstrated the rocket's reliability and its ability to deliver payloads into orbit.

First commercial launch: In December 2020, the Angara 1.2 rocket completed its first commercial launch, delivering two Russian satellites into orbit. This marked an important milestone for the rocket, as it demonstrated its ability to compete in the commercial launch market.

Future potential: The Angara 1.2 rocket is expected to play an important role in Russia's space program in the coming years. Roscosmos has announced plans to use the rocket for a variety of missions, including launches of military and civilian satellites, as well as deep space exploration missions.

Conclusion:

The Angara 1.2 rocket is an important achievement for Russia's space program. It represents a major step forward in the country's efforts to develop a new generation of space launch vehicles that can replace the aging Soyuz rockets. The development of the rocket was a long and difficult process, but the successful launches and achievements of the Angara 1.2 rocket have demonstrated that the effort was worth it. The rocket has proven to be reliable and capable of delivering payloads into orbit, and it has even entered the commercial launch market. The Angara 1.2 rocket is expected to have a bright future, as it will play an important role in Russia's space program and contribute to the exploration of deep space. With its advanced design and technology, the Angara 1.2 rocket is poised to make significant contributions to the future of space exploration.
