Unlike the ISS, which stays in Low Earth Orbit, Gateway will be positioned in a unique . This "halo" path allows the station to: Stay in constant contact with Earth. The Gateway

The Gateway isn't just a destination—it's the front door to the rest of the solar system.
This isn't just a U.S. project. Agencies from around the world are contributing critical modules:
The first elements, PPE and HALO, are slated to launch together on a SpaceX Falcon Heavy . While there have been strategic shifts and debates about the station's role versus surface bases, the Gateway remains a critical "stepping stone" for sustainable deep-space exploration.
