Evaluation of Vegetation Bias in InSAR Time Series for Agricultural Areas Within the San Joaquin Valley, CA

open access: yesEarth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Agricultural regions present a particularly difficult set of challenges during interferometric synthetic aperture radar (InSAR) displacement time series analyses due to the existence of abrupt transitions in land use over short spatial scales and rapid temporal changes associated with different stages of the agricultural cycle.

Searching for mid-range planar orbits to observe deimos

open access: yes, 2019
In this paper we search for mid-range planar orbits for a spacecraft traveling in the neighborhood of Deimos. The first task is to perform a numerical search to find and classify mid-range natural orbits around Deimos that are dominated by Mars, using ...

Fluidly Revealing Information: A Survey of Un/foldable Data Visualizations

open access: yesComputer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract Revealing relevant information on demand is an essential requirement for visual data exploration. In this state‐of‐the‐art report, we review and classify techniques that are inspired by the physical metaphor of un/folding to reveal relevant information or, conversely, to reduce irrelevant information in data visualizations.

Two Possible Orbital Histories of Phobos

open access: yesThe Planetary Science Journal
The two moons of Mars, Phobos and Deimos, have orbits that are close to the Martian equator, indicating their formation from a circumplanetary disk. Phobos is currently migrating toward Mars due to tidal dissipation within the planet and may be disrupted

A mission concept of Phobos/Deimos exploration [PDF]

open access: yes, 1993
We have been designing the concept of Phobos/Deimos mission using the Japanese H-2 rocket as a first step in asteroid exploration. In planning the mission concept, we focused on development of methods to characterize the materials of Phobos/Deimos.

Physically Based Real‐Time Rendering of Eclipses

open access: yesComputer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract We present a novel approach for simulating eclipses, incorporating effects of light scattering and refraction in the occluder's atmosphere. Our approach not only simulates the eclipse shadow, but also allows for watching the Sun being eclipsed by the occluder.

MIRS: an imaging spectrometer for the MMX mission

open access: yesEarth, Planets and Space, 2021
The MMX infrared spectrometer (MIRS) is an imaging spectrometer onboard MMX JAXA mission. MMX (Martian Moon eXploration) is scheduled to be launched in 2024 with sample return to Earth in 2029.

One schema to rule them all: How Schema.org models the world of search

open access: yesJournal of the Association for Information Science and Technology, Volume 76, Issue 2, Page 460-523, February 2025.
Abstract Several industry‐specific metadata initiatives have historically facilitated structured data modeling for the web in domains such as commerce, publishing, social media, and so forth. The metadata vocabularies produced by these initiatives allow developers to “wrap” information on the web to provide machine‐readable signals for search engines ...

Space‐Weathered Anorthosite as Spectral D‐Type Material on the Martian Satellites

open access: yesGeophysical Research Letters, 2018
Spectral D‐type asteroids are characterized by dark, red‐sloped, and featureless spectra at visible and near‐infrared wavelengths and are thought to be composed of rocks rich in organic compounds.
