In Situ Observations of Interplanetary Dust Variability in the Inner Heliosphere

This work examines the variation of interplanetary dust count rates and directionality during the first three solar encounters made by the Parker Solar Probe spacecraft, covering distances between 0.65 au (\~140 solar radii, RS) and 0.16 au (\~35 RS). Dust detections are made by the FIELDS instrument via plasma clouds, produced by impact ionization of dust grains on spacecraft surfaces and resultant spacecraft potential perturbations. Dust count rates and inferred densities are found to vary by \~50\ ...

Examining Dust Directionality with the Parker Solar Probe FIELDS Instrument

Parker Solar Probe\textquoterights (PSP\textquoterights) FIELDS instrument provides a measure of the dust impact rate on the spacecraft with a full-coverage summary of the voltages recorded by the spacecraft\textquoterights antennas. From consecutively sampled periods throughout PSP\textquoterights orbit, FIELDS stores the maximum amplitude measured by each active antenna. The occurrence of a dust impact during a given period can be identified by these amplitudes exceeding a few tens of millivolts, and a dust grain\textqu ...

The Near-Sun Dust Environment: Initial Observations from Parker Solar Probe

The Parker Solar Probe (PSP) spacecraft has flown into the densest, previously unexplored, innermost region of our solar system\textquoterights zodiacal cloud. While PSP does not have a dedicated dust detector, multiple instruments on the spacecraft are sensitive to the effects of meteoroid bombardment. Here, we discuss measurements taken during PSP\textquoterights second orbit and compare them to models of the zodiacal cloud\textquoterights dust distribution. Comparing the radial impact rate trends and the timing and loc ...
