Atacama Desert’s Unprecedented Rains Are Lethal to Microbes

Katherine Kornei, Science Writer by Katherine Kornei 12 November 201812 April 2022

Rainfall in the driest parts of Chile’s Atacama Desert in 2017 resulted in hypersaline lagoons that killed the majority of microbes adapted to millions of years of arid conditions.

Pools of briny water likely exist on Mars. Some might even exist in Gale Crater, Curiosity’s landing site, seen here.

Evidence of Regional Deposition in Mars’s South Polar Deposits

by Terri Cook 13 August 20188 August 2022

Shallow Radar correlation of discrete units in one of the Red Planet’s largest ice reservoirs suggests that its material was emplaced as a single, regional deposit.

Researchers analyze rocks from Mars’s Gale crater to see whether the conditions under which they formed were really as Earthlike as previously believed.
