The frequency of flights to the future Russian Orbital Service Station (ROSS) will be higher compared to space missions to the International Space Station (ISS), Roscosmos Chief Dmitry Rogozin said on Monday.

"The frequency of flights will be higher and that is why it [a spacecraft] must be cheaper," the Roscosmos head said after a ceremony to present the Russian government's Yuri Gagarin Space Awards for 2021.

The Roscosmos administrator said he had given instructions to Chief Designer of the Energia Space Rocket Corporation Vladimir Solovyov to consider creating a universal crewed and resupply ship dubbed Orlyonok (a derivative of the Oryol spaceship) for flights to the ROSS. "The Energia Space Rocket Corporation will necessarily outline both the ROSS architecture and how to fly there," he pointed out.
