Distal Ejecta from Lunar Impacts: Extensive Regions of Rocky Deposits

open access: yes, 2016
Lunar Reconnaissance Orbiter (LRO) Diviner Radiometer, Mini-RF, and LRO Camera data were used to identify and characterize rocky lunar deposits that appear well separated from any potential source crater.

Critical Multilingual Language Awareness, Antiracism, and Raciolinguicized Subjectivities in Teacher Education

open access: yesTESOL Quarterly, EarlyView.
Abstract Race and language collaborate in structuring educational inequities, creating urgency for teacher education to equip all teachers to equitably serve racialized multilinguals as antiracist language educators. Emphasizing the inseparability of racial and linguistic justice, this article examines teacher candidates' (TCs') learning journeys ...

Observation depuis le sol et analyse des émissions associées aux chutes des météorites sur la lune [PDF]

open access: yes, 2016
Meteoroids, coming from small bodies of the solar system, produce luminous phenomena (impact flashes) when they strike the lunar surface. These transient light events are observable from the ground using medium-sized telescopes (typically> 200 mm in ...

Lunar Impact Optimization

open access: yes
Natural celestial collision processes are rich in nonlinear dynamical characteristics and energy distribution patterns. In particular, the complex geomorphic phenomena produced by asteroid impacts on the Moon, such as crater formation, multi-ring basin structures, ejecta distribution patterns, and energy transfer at different scales, provide unique ...

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

open access: yesWildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

The micrometeorite flux to Earth through the Phanerozoic Eon : Reconstructed using sediment-dispersed extraterrestrial spinels [PDF]

open access: yes, 2021
The purpose of this thesis is to add an astronomical component to the history and evolution of Earth by reconstructing the micrometeorite flux to Earth at different time intervals during the Phanerozoic Eon, using sediment-dispersed extraterrestrial ...

Model for Determining the Origin of Lunar Volatiles Based on Their Composition: Application to NASA’s VIPER and Other Landed Missions

open access: yesThe Planetary Science Journal
Lunar volatiles provide a potentially pristine record of the history of the Earth–Moon system in terms of both geologic activity and delivery of volatiles from the outer solar system.

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space

open access: yesThe Modern Law Review, EarlyView.
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

The detectability of lunar impacts in the near infrared

open access: yes, 1996
Impact crater scaling laws are used to predict the diameter and amount of melt produced in impacts on quartz sand of projectiles with mass from 100 gm to 100 kg and velocity from 20-40 km/sec.

Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

open access: yesGlobal Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.
