A New Era of Science on the Lunar Gateway Space Station

Gateway, orbiting the Moon, will study solar and cosmic radiation to understand space weather, crucial for the Artemis missions and future Moon and Mars travels. Its instruments, HERMES, ERSA, and IDA, will monitor radiation levels, aiding in health risk assessments and space travel safety.

Much of the initial science taking place on the Gateway space station that will orbit the Moon will focus on radiation from the Sun and deep space.

A trio of radiation instruments planned for Gateway, an important element of NASA’s Artemis missions, will help scientists better understand how to plan for the unpredictable space weather resulting from the Sun and galactic cosmic rays from deep space that astronauts, spacecraft, and hardware will encounter on travels to the Moon and Mars.
