The International Space Station is the current biggest and most valuable Space Station in the world, a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies, But as space becomes more accessible and cheaper, more and more space organizations and companies will try to send their one space station.
More space station is better for sustainable space infrastructure and it will also help space to become accessible to normal people in future.
The Lunar Gateway, or just Gateway, is a proposed tiny space station in lunar orbit that will act as a solar-powered communication center, science laboratory, short-term living module for government personnel, and a holding place for rovers and other robots.
The Russian Orbital Service Station is a proposed Russian orbital space station scheduled to begin construction in 2025. Initially an evolution of the Orbital Piloted Assembly and Experiment Complex (OPSEK) concept, ROSS developed into plans for a new standalone Russian space station built from scratch without modules from the Russian Orbital Segment of the ISS.

ISRO chairman K. Sivan announced in 2019 that India will not join the International Space Station and will instead build a 20-tonne space station on its own. It is intended to be built in the next 5–7 years.
The Lunar Orbital Station is a proposed Russian space station in lunar orbit. In 2007, the concept was presented during a presentation at the Gagarin Cosmonaut Training Center in Star City. It is one of two components of the Russian lunar infrastructure, the other being a base on the Moon’s surface.
Six docking ports, a high-power antenna for communications, maneuvering and attitude control engines, solar panels, and a robotic arm would be included in LOS. The station’s components would be launched on a super-heavy Angara rocket.
Russia has expressed dissatisfaction with its position in the international Lunar Gateway, prompting the government to move forward with plans for its own lunar base. The first LOS module is scheduled to deploy in 2025.
