"Curiosity Rover Explores Ancient Martian Riverbed"

NASA's Curiosity rover is embarking on a new phase of exploration on Mars, venturing into what scientists believe is the dried-up bed of an ancient river called Gediz Vallis. The rover will investigate the area to gain insight into the Martian environment and the possibility of past or present life on the Red Planet. Scientists are intrigued by the possibility that the channel was formed by flowing liquid water, indicating a resurgence of water on Mars after a long dry period. Curiosity will spend months exploring the channel, providing valuable information about the Martian landscape and its history.

Unintentional Destruction: The Lost Opportunity to Discover Life on Mars

The Viking landers, sent to Mars in the 1970s, conducted the only life detection experiments on another planet. The results were initially confusing, with some tests suggesting the presence of life while others did not. Recent discoveries have shown that indigenous organic compounds do exist on Mars, but in a different form than expected. A new hypothesis suggests that the Viking experiments may have inadvertently killed Martian life by applying water to the soil samples, overwhelming the microbes. The presence of hygroscopic salts and hydrogen peroxide in Martian soil could explain the puzzling results. A new mission dedicated to life detection on Mars is needed to further investigate this hypothesis.
