Imagining a new era of planetary field geology [PDF]
Science Advances, 2019 Kip V. Hodges Harrison H. Schmitt July marked the beginning of a 3-year-long celebration of one of the most remarkable periods of human exploration in history: the Apollo missions to the Moon. Reflections on Apollo have inspired a renewed international interest in sustained lunar exploration.

Advanced Science, EarlyView.Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.
