Some recent results of collection experiments in the upper atmosphere by rocket techniques, by balloon collections in the intermediate atmosphere, and by recoverable satellites in near-earth space are described. Evidence is presented for the existence of relatively high and variable fluxes of submicron particles entering the atmosphere. These submicron-particle collections are consistent with implications from zodiacal light studies, provided the particles have a solar origin and are drifting outward with a constant radial velocity. A simple estimate suggests that these particles, by virtue of their refractory nature, can survive ejection from the sun near sunspots.
