In this study, we developed and implemented a deep learning program to classify the suitability of regions for landing on the Moon's south pole, utilizing data from NASA's Lunar R…

The Importance of Geospatial Technology in Monitoring Plant Health

Solving the problems presented by climate change depends on geospatial technology in great measure. Through shifting pest and disease dynamics, increasing frequency of extreme wea…

Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions

Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re-entry rates, emitting pollutants throughout the atmosphere. The environmental cost of SMCs …

Reshaping of San Jose Island, TX, USA, by unconfined washover and channelized washout during Hurricane Harvey

Hurricane Harvey (2017) produced 31 net-erosional washout channels on San Jose Island, Texas, USA where offshore-directed flows cut through two dune ridges and the beach. These ch…

Deep-seated landslide stability on curved basal surfaces with and without glacier buttressing

Glacial retreat strongly influences landslide dynamics, yet the controls on stability and transient acceleration remain unclear. Many deep-seated landslides accelerate during ice …
