Russia is planning to develop a reusable rocket aimed at reducing space launch costs, following the approach pioneered by SpaceX, Dmitry Bakanov, the chief executive of Russia’s state space agency, Roscosmos, said in an interview with business daily RBC on Monday.

“Elon Musk’s approach has shown that while previous rocket stages were discarded as scrap after initial use, reusing the first stage multiple times has led to significant savings and increased efficiency,” said Bakanov.

The Roscosmos chief also told RBC that the technical specifications for developing Russia’s reusable rocket technology were approved in June. Bakanov also estimated that it would be completed in 18 to 24 months.

“Thorough and quality development is of the utmost importance. While it would be possible to attempt a test in the immediate future, the results would not be satisfactory,” he said.

Bakanov also pointed out that, beyond the United States, China and Japan have each developed reusable first-stage rockets. Currently, most booster stages become uncontrollable after separation and fall either to the ground or into the ocean. Reusable launch vehicles can return to Earth intact, so that they can be reused.

SpaceX first demonstrated this technology in 2010 with the launch of the Falcon 9 reusable rocket. Since then, the company has conducted approximately 500 launches, accounting for 99.4% of all attempts.
