Dust Ablation on the Giant Planets: Consequences for Stratospheric Photochemistry

, 2017
Ablation of interplanetary dust supplies oxygen to the upper atmospheres of Jupiter, Saturn, Uranus, and Neptune. Using recent dynamical model predictions for the dust influx rates to the giant planets (Poppe, A.R.~et al.~[2016], Icarus 264, 369), we ...

Prediction of the In-Situ Dust Measurements of the Stardust Mission to Comet 81P/Wild 2 [PDF]

, 1999
We predict the amount of cometary, interplanetary, and interstellar cosmic dust that is to be measured by the Cometary and Interstellar Dust Analyzer (CIDA) and the aerogel collector on-board the Stardust spacecraft during its fly-by of comet P/Wild 2 ...

Re‐Analysis of Pioneer Venus Data: Water, Iron Sulfate, and Sulfuric Acid are Major Components in Venus' Aerosols

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We present a new and transformative composition for Venus' cloud aerosols using previously uncharacterized data acquired by the Pioneer Venus Large Probe, which descended through Venus' atmosphere in 1978. This aerosol composition was extracted by re‐analyzing data acquired by the Large Probe Neutral Mass Spectrometer (LNMS) and re‐evaluating ...

Correlated analyses of D- and 15N-rich carbon grains from CR2 chondrite EET 92042 [PDF]

, 2006
Extract from introduction: Insoluble organic matter (IOM) and matrix from primitive carbonaceous chondrites carry isotope enrichments (?D?20000', ?15N?3200�) that are comparable to those in interplanetary dust particles [1, this work]. Hence, primitive

Compression‐Expansion: Miniaturization, Modularity, and Logistics Beyond Earth

American Anthropologist, Volume 127, Issue 3, Page 424-434, September 2025.
ABSTRACT If the Cold War space race culminated in a return to Earth, at present we are experiencing a renewed interest in space. Drawing on fieldwork among people working in the space sector in Sweden, this article focuses on some of the imaginaries underpinning this resurgence and the contemporary commercialization of space. Specifically, I hone in on

Determination of the Far-Infrared Cosmic Background Using COBE/DIRBE and WHAM Data

, 2007
Determination of the cosmic infrared background (CIB) at far infrared wavelengths using COBE/DIRBE data is limited by the accuracy to which foreground interplanetary and Galactic dust emission can be modeled and subtracted. Previous determinations of the

Solar Wind Heavy Ions and Alpha Particles Within Earth's Magnetosphere and Their Variability With Upstream Conditions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract Working toward the goal of understanding solar wind (SW) entry to the Earth's magnetosphere, this study examines solar‐origin ion composition in the magnetotail. During its trajectory, Wind spent a significant amount of time in the Earth's magnetotail, where its SupraThermal Ion Composition Spectrometer (STICS) measured the mass and mass per ...

Impact-Generated Dust Clouds Surrounding the Galilean Moons

, 2003
Tenuous dust clouds of Jupiter's Galilean moons Io, Europa, Ganymede and Callisto have been detected with the in-situ dust detector on board the Galileo spacecraft.
