NASA Presentation: Exploring Mars Together: Draft for Community Feedback (2023)
Editor’s note: this presentation at NASA was assembled in 2023 prior to the cancellation of the Mars Sample Return Mission. While the notion of returning samples from Mars by NASA […]
An Atacama Desert Microbial Community As A Model For Astrobiology
The grit crust is a recently discovered, novel type of biocrust made of prokaryotic cyanobacteria, eukaryotic green algae, fungi, lichens and other microbes that grow around and within granitoid stone […]
Adaptations Of Endolithic Communities To Abrupt Environmental Changes In A Hyper-arid Desert
The adaptation mechanisms of microbial communities to natural perturbations remain relatively unexplored, particularly in extreme environments. The extremophilic communities of halite (NaCl) nodules from the hyper-arid core of the Atacama […]
Raman Spectroscopy And Planetary Exploration: Testing The ExoMars/RLS System At The Tabernas Desert (Spain)
ExoFit trials are field campaigns financed by ESA to test the Rosalind Franklin rover and to enhance collaboration practices between ExoMars working groups. During the first trial, a replicate of […]
Two Decades of km-resolution Satellite- And Ground-based Measurements of the Precipitable Water Vapor in the Atacama Desert
The Atacama Desert has long been established as an excellent site for submillimeter observations. Yet identifying potentially optimal locations for a new facility within this region can require long field […]
Desert Mosses Use Quartz Rocks As Sun Shades
Living under a translucent rock can be quite comfortable — if you’re a moss in the Mojave Desert. A graduate student at the University of California, Berkeley, found that some […]
Mineralogy of a Sulfate-rich Inverted Channel in the Atacama Desert, Chile: Clues to its Formation and Preservation
We have performed a stratigraphic and mineralogical analysis of a vertical transect across a ridge located at the distal end of a system of eroded alluvial deposits in the northern […]
Cellular Life From The Three Domains And Viruses Are Transcriptionally Active In A Hypersaline Desert Community
Microbial communities play essential roles in the biosphere and understanding the mechanisms underlying their functional adaptations to environmental conditions is critical for predicting their behavior. This aspect of microbiome function […]
Atacama Desert Microbes May Hold Clues To Life On Mars
Microbial life on Mars may potentially be transported across the planet on dust particles carried by wind, according to a study conducted in the Atacama Desert in North Chile, a […]
