The Atacama Desert is by far the driest and oldest desert on Earth, showing a unique combination of environmental extremes (extreme dryness, the highest UV radiation levels on Earth and highly saline and oxidizing soils), explaining why the Atacama has been largely investigated as a Mars analog model for almost twenty years. Based on the source and the amount of water available for life and its analogy with Mars, two ecosystems are of interest in the Atacama; its Coastal Range and the much drier hyperarid core, which we here review in detail. Members of the three domains of life have been found across these ecosystems living at the limit of habitability, suggesting the potential dry limits for each domain, and also unveiling the highly patchy distribution of microbial life in its most extreme regions. The through study of the Atacama have allowed to understand how life has adapted to its extreme conditions, the specific habitats that life occupies in each case, (thus suggesting the mos

NASA’s First Weather Report From Jezero Crater on Mars
Perseverance’s MEDA will help us understand how to prepare astronauts for a future on the Red Planet.
The weather often plays a role in our daily plans. You might put on a light jacket when the forecast calls for a cool breeze or delay your travel plans because of an impending storm. NASA engineers use weather data to inform their plans, too, which is why they’re analyzing the conditions millions of miles away on Mars.
The Mars Environmental Dynamics Analyzer (MEDA) system aboard NASA’s Perseverance rover first powered on for 30 minutes Feb. 19, approximately one day after the rover touched down on the Red Planet. Around 8:25 p.m. PST that same day, engineers received initial data from MEDA.
