Ultralow-density double-layer silica aerogel fabrication for the intact capture of cosmic dust in low-Earth orbits

Journal of Sol-Gel Science and Technology, 2015
The fabrication of an ultralow-density hydrophobic silica aerogel for the intact capture cosmic dust during the Tanpopo mission is described. The Tanpopo experiment performed on the International Space Station orbiting the Earth includes the collection ...

Cosmic Dust: Collection and Research

Annual Review of Earth and Planetary Sciences, 1985
The term "cosmic dust" as used here refers to particulate material that exists or has existed in the interplanetary medium as bodies smaller than 1 mm. The particles can be collected both in space and in the terrestrial environment, and they are a valuable resource of meteoritic material. The dust samples are complementary to the traditional meteorites

Orientation of cosmic dust grains

Astrophysics and Space Science, 1976
Orientation of nonspherical cosmic dust grains is found in anisotropic corpuscular or radiative fluxes and in the presence of the magnetic field; cosmic grains being approximated by axially symmetric ellipsoids. A comparatively small twisting of grains is shown to cause differences in scattering right-hand and left-hand circularly polarized photons and

Applications: Cosmic Dust Grains

2003
Although the importance of cosmic dust has long been recognized in astronomy, only a partial understanding of the nature of dust grains has been achieved. In fact, most of the information on the interstellar matter that forms the so-called interstellar medium (IST) comes from spectroscopical analysis and from the study of the extinction of the ...

COSMIC DUST COLLECTION IN AEROGEL

Annual Review of Earth and Planetary Sciences, 2006
Aerogel is an ultra-low-density material that can be used to capture small particles incident upon it at speeds in excess of 1 km s−1. This permits capture of cosmic dust in space where the high speeds usually result in destructive impact events. The performance of aerogel in laboratory impact tests is described.

Cosmic dust and our origins

Surface Science, 2002
Abstract The small solid particles in the space between the stars provide the surfaces for the production of many simple and complex molecules. Processes involving the effects of ultraviolet irradiation of the thin (hundredth micron) mantles are shown to produce a wide range of molecules and ions also seen in comets.
