  1. This is the "Vacuum Monster" a balloon-borne instrument to collect #interplanetary dust particles in the #stratosphere

    It was developed in the 70s by Dr. Donald #Brownlee at Washington University and named after the creature in the #Beatles movie Yellow Submarine that sucked up everything.

    It consisted basically of an air pump that pulled air through an array of cylindrical collection rods. Particles are collected on the oil-coated rods by inertial deposition.
