The Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO) are the foundational elements of NASA's lunar-orbiting space station "Gateway". The PPE is a 60-kilowatt class solar electric propulsion spacecraft that also will provide power, high-speed communications, attitude control and the capability to move the Gateway to different lunar orbits. The HALO is the pressurized living quarters where astronauts who visit the Gateway, often on their way to the Moon, will work. It will provide command and control and serve as the docking hub for the outpost. HALO will support science investigations, distribute power, provide communications for visiting vehicles and lunar surface expeditions, and supplement the life support systems aboard Orion, NASA’s spacecraft that will deliver Artemis astronauts to the Gateway.
Lunar OrbitThe JPSS constellation of satellites collects global multi-spectral radiometry and other specialized meteorologic, oceanographic, and solar-geophysical data via remote sensing of land, sea, and atmospheric properties. These data support NOAA’s mission for continuous observation of Earth’s environment to understand and predict changes in weather, climate, oceans, and coasts to support the nation’s economy and protect lives and property. NASA uses the instruments aboard the JPSS satellites to continue decades of Earth science research for the betterment of humanity. JPSS-4 carries the NASA Earth Venture mission Libera, an instrument to improve our understanding of trends in Earth’s energy imbalance and our changing climate.
Sun-Synchronous Orbit3.7-ton South Korean geostationary communications satellite also known as Chollian-3. Designed to replace GEO-Kompsat-1 launched in 2010, it features advanced payloads for communications, disaster prevention, maritime safety and the safe flight of aircraft
Geostationary Transfer OrbitThaicom 10, built by Airbus Defence and Space, will provide over 120 gigabits per second (Gbps) of capacity, with flexibility and instant configuration to adapt dynamically to the customers’ needs. The satellite will provide extended connectivity over the region for Thaicom’s customers and partners across the Asia Pacific.
