Interplanetary dust particles (IDPs), ∼ 10μm particles from comets and asteroids, have been collected by NASA from the Earth's stratosphere. We compared carbon X-ray Absorption Near-Edge Structure (XANES) and Fourier Transform Infra-Red (FTIR) spe

Interplanetary dust particles accumulate significant concentrations of noble gases, implanted by the solar wind and solar energetic particles, while they are in space. When these dust particles enter the atmosphere of a planet they are heated and dec

Two major sources are observed to contribute to the Zodiacal Cloud: main-belt asteroids and active comets. However, the discovery of 100 km size objects in trans-Neptunian orbits (Jewitt & Luu 1993) coupled with Pioneer 10 measurements showing an ess

Here we describe the critical role that synchrotron X-ray and infrared microprobes are playing in the search for interstellar dust in the Stardust Interstellar Dust Collector (SIDC). The samples under examination are submicron particles trapped in lo

Individual interplanetary dust particles can experience alteration or contamination by a variety of mechanisms during Earth encounter. Velocity selection effects produce a stratospheric dust population different from the interplanetary dust populatio

The interplanetary dust particles collected from the Earth’s stratosphere are believed to sample both the asteroids and the comets. Near‐earth gravitational segregation favors collection of the lowest velocity interplanetary dust, from the main

This paper presents results of a fission track investigation of the minor mineral phase chromite in the Allende meteorite. Although this mineral is a possible carrier of much of the meteorite's isotopically anomalous xenon, there are at least two ord
