Groundwater Sapping in Hack Crater (Mars): Geologic Evidence and Geophysical Modeling of Groundwater Stability

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract This study investigates Hack crater in Arabia Terra on Mars, which exhibits remarkable water‐related landforms, suggesting a period of intense water activity despite lacking a connection with large‐scale fluvial networks. Instead, short valleys within its walls display morphologies indicative of mass‐wasting processes driven by groundwater ...

Mining and/in outer space: Verticality, analogy, and infrastructural mediation in subarctic Sweden Les mines et/dans l'espace : verticalité, analogie et médiation infrastructurelle dans les régions subarctiques de Suède

Journal of the Royal Anthropological Institute, Volume 31, Issue 2, Page 605-625, June 2025.
Space activities in subarctic Sweden are predicated on older infrastructures of underground resource extraction. The ongoing expansion of the country's rocket launch site outside Kiruna relies on the Swedish state's historical construction of the region as a resource frontier.
