NASA Mission to Study Giant ‘Halo’ Surrounding Earth

From a vantage point roughly one million miles closer to the Sun than Earth is, the Carruthers Geocorona Observatory will capture the most comprehensive views of the geocorona to date. The observations will reveal new insights into the structure of our atmosphere, how solar eruptions impact Earth, and how a planet’s surface water can escape to space, aiding the search for habitable planets elsewhere in the universe.
