The Russian space agency just revealed a model of its own space station to compete with the International Space Station.

Russia has been threatening to pull out of the International Space Station for months. Yury Borisov, the new head of Russia's Roscosmos, said that Russia will leave the International Space Station after 2024. Borisov said that the decision to leave the station after 2024 had been made. The Russian orbital station will be assembled by this time.

At a military-industrial exhibition outside Moscow, a model of its own space station was on display. The Russian space station would be launched in two phases. Two more modules and a service platform would be added in the second phase of the project. According to Russia's state media, the first phase of the project would launch in 2025, and the second phase in 2035.

Russia may stay on the International Space Station until after 2024, according to the ambitious timelines. The space agency had a backup plan in case the Russian space agency decided to pull out of their partnership. It is not clear how the construction of a space station will be pulled off under the sanctions imposed on Russia by the international community.

NASA and Roscosmos have been partners for more than 20 years. There have been at least two people on the space station at the same time. The Russian space agency acted up in response to the sanctions. In July of this year, the Russian space agency posted photos on its official Telegram channel of three cosmonauts holding up the flags of Russian-backed regions in Ukraine. The European Space Agency's director general was challenged to fly to space by the former head of the Russian space agency.

Although the space agency is not promising to stay on board the space station until it dies, it has been less aggressive since the departure of Rogozin. There is a model of ROSS on display that seems to show a longing for independence.

The U.S. officials are not happy about the satellite.
