  • A groundbreaking X-ray imager is on its way to revolutionize our understanding of Earth's magnetic defenses. This cutting-edge instrument, the Lunar Environment Heliospheric X-ray Imager (LEXI), is central to NASA's Artemis campaign.

NASA's LEXI (Lunar Environment heliospheric X-ray Imager) is set to revolutionize our understanding of Earth's magnetosphere by providing the first-ever global images of this protective magnetic environment. Scheduled for launch in 2025 as part of the Artemis III mission, LEXI will be positioned on the lunar surface to capture X-ray emissions from solar wind charge exchange (SWCX), which occurs when solar wind particles interact with Earth's magnetosphere. This imaging will not only offer insights into the dynamics of the magnetosphere but also help in understanding space weather effects on Earth, satellite operations, and astronaut safety. By visualizing the magnetosphere, LEXI will aid in studying how solar wind influences Earth's magnetic field, potentially enhancing our ability to predict and mitigate space weather impacts.
