NASA’s next mission to the Moon will carry an instrument called LEXI (the Lunar Environment Heliospheric X-ray Imager), which will provide the first-ever global view of the magnetic environment that shields Earth from solar radiation.
From the surface of the Moon, LEXI will capture wide-field images of Earth's magnetic environment, or magnetosphere, in low-energy (or "soft") X-rays. LEXI will study changes in the magnetosphere and help us learn more about how it interacts with a stream of particles from the Sun called the solar wind, which can pose hazards for Artemis astronauts traveling to the moon
