Linking meteorites to their asteroid parent bodies: The capabilities of dust analyzer instruments during asteroid flybys

open access: yesMeteoritics &Planetary Science, Volume 58, Issue 10, Page 1449-1468, October 2023., 2023
Abstract Linking meteorites to their asteroid parent bodies remains an outstanding issue. Space‐based dust characterization using impact ionization mass spectrometry is a proven technique for the compositional analysis of individual cosmic dust grains.

Potential Themis-family Asteroid Contribution to the Jupiter-family Comet Population [PDF]

open access: yesAstronomical Journal, 2020
Recent dynamical analyses suggest that some Jupiter family comets (JFCs) may originate in the main asteroid belt instead of the outer solar system. This possibility is particularly interesting given evidence that icy main-belt objects are known to be ...

In Situ Optimized Substrate Witness Plates: Ground Truth for Key Processes on the Moon and Other Planets

open access: yesEarth and Space Science, Volume 10, Issue 9, September 2023., 2023
Abstract Future exploration efforts of the Moon, Mars, and other bodies are poised to focus heavily on persistent and sustainable survey and research efforts, especially given the recent interest in a long‐term sustainable human presence at the Moon.

Buried Ice Deposits in Lunar Polar Cold Traps Were Disrupted by Ballistic Sedimentation

open access: yesJournal of Geophysical Research: Planets, Volume 128, Issue 5, May 2023., 2023
Abstract The NASA Artemis program will send humans to the lunar south polar region, in part to investigate the availability of water ice and other in situ resources. While trace amounts of ice have been detected at the surface of polar permanently shadowed regions (PSRs), recent studies suggest that large ice deposits could be stable below cold traps ...

Quantifying the Hypervolatile Abundances in Jupiter-family Comet 46P/Wirtanen

open access: yesThe Planetary Science Journal, 2021
We present analysis of IR and optical spectroscopy of Jupiter-family comet (JFC) 46P/Wirtanen obtained in 2019 January, when the comet had sufficient geocentric velocity to enable studies of the hypervolatiles CO and CH4, as well as [O i] emission. These

Space in 150 years: From fantasy through fiction to fact and function [PDF]

open access: yes, 2015
In the last century and a half, space has moved from the realm of fantasy to everyday reality. In parallel, the way space has been regarded by the person in the street and the ideas of what access to space might be used for have evolved extraordinarily.

50 Years in Space Science

open access: yesPerspectives of Earth and Space Scientists, Volume 3, Issue 1, December 2022., 2022
Abstract These are my personal recollections of my 50‐year involvement in planning NASA space projects, including the Voyager Missions, The Hubble Space Telescope, the International Space Station, the Space Shuttle, the Falcon Space X launcher, and the James Webb Space Telescope.

Physical characterization of equal-mass binary near-Earth asteroid 2017 YE5: a possible dormant Jupiter-family comet

open access: yesMonthly notices of the Royal Astronomical Society, 2021
Photometric observations of the nearly equal-mass binary near-Earth asteroid 2017 YE5 were carried out at the Observatório Astronômico do Sertão de Itaparica (OASI, Brazil) and at the Blue Mountains Observatory (BMO, Australia) between 2018 July and ...

James van Allen and his namesake NASA mission [PDF]

open access: yes, 2013
In many ways, James A. Van Allen defined and “invented” modern space research. His example showed the way for government-university partners to pursue basic research that also served important national and international goals.

29P/Schwassmann–Wachmann 1, A Centaur in the Gateway to the Jupiter-family Comets [PDF]

open access: yesAstrophysical Journal, 2019
Jupiter-family comets (JFCs) are the evolutionary products of trans-Neptunian objects (TNOs) that evolve through the giant planet region as Centaurs and into the inner solar system.
