"It will be 80 percent composite…the spacecraft will be made of composite materials while the reusable landing capsule will be built from traditional materials," Energia General Director Vladimir Solntsev told reporters in Moscow.
According to Energia, the Federation spacecraft has been designed to deliver up to four people and cargo to the Moon and space stations in low Earth orbits. The spacecraft’s autonomous flight period is estimated at up to 30 days, with the capacity to stay attached to a space station for up to a year.
The first unmanned test flight of the Federation has been scheduled for 2021, while the maiden manned flight is expected in 2023.
The Federation will replace the aging Soyuz spacecraft in supporting low Earth orbit missions.
