Illuminating Permanently Shadowed Lunar Regions Using a Solar Sail

Sunlight can be reflected into permanently shadowed regions (PSRs) using S/C solar sails in order to detect and confirm the presence and distribution of water ice cold-trapped in PSRs in lunar polar craters. This reflected light is then viewed with an optical spectrometer.

Process to Fabricate Specific Sized Monodisperse Polystyrene Microparticles

A new method was developed to prepare monodisperse nano to microparticles of polystyrene ranging from 0.5 to 2.5 microns in relatively large-quantity batches (2 L, 10% by weight in water). Current commercial sources are very expensive and can typically only be acquired...

High-Density, Homogenous Bacterial Spore Distributions on Test Surfaces

Thus far, spore transfer had been successful from the polycarbonate membrane onto stainless steel, aluminum, and to some extent, glass. In order to image the endospores under an ESEM (environmental scanning electron microscope), the spores were transferred onto a...
