Associate Research Scholar Jamey Szalay has recently reported on results from the NASA Parker Solar Probe’s encounter with a Zodiacal dust cloud in the inner Solar system. Based on data collected by the FIELDS instrument during Parker’s first six orbits, Szalay and his colleagues identified three different populations of dust in the zodiacal cloud. Most of the grains are being slowly pulled in toward the Sun, a second population of small grains generated in collisions is being pushed by radiation pressure from sunlight toward the outer solar system, and a third group appears to have been created by a "tube” of cometary debris collides with grains from the first two populations.

Szalay’s article, was published Sept. 9 by Planetary Science Journal.
