Solar wind energy particles and interplanetary magnetic field data from Sun-Earth point L1.Share this page: twitter facebook linkedin
Advanced Composition Explorer (ACE) is a spacecraft laboratory, orbiting the Sun-Earth first libration point. Its mission is the measurement of solar wind and the interplanetary magnetic field at Sun-Earth L1 Lagrange point, some time before solar particles reach our planet.
