When the Viking 1 lander send down twin landers to study Mars in 1976, the results returned a negative result for the possibility of microbial life. However, for years, scientists have argued that the Viking's experimental techniques might’ve killed hygroscopic microbes living on Mars with too much water.

While on the hunt for signs of ancient microbial life on Mars, NASA’s Curiosity rover captured a mysterious field of white sulfur stones in a series of striking new images. Curosity - which left Earth on its missing 13 years ago - first discovered the ...

According to astrobiologist Dirk Schulze-Makuch of the Technical University Berlin in Germany, an experiment to detect the signs of microbial life on Mars could have been deadly.

Oops? Life on Mars may have been found — before it was accidentally destroyed during a NASA mission nearly 50 years ago, one scientist has suggested. In 1975, just six years after Apollo 11 touched down on the moon,

A scientist has said NASA may have accidentally killed life on Mars during a research mission to find it. For decades, scientists have been trying to find any signs of life on the Red Planet with no conclusive evidence as of yet.

For decades, scientists have posited that to find life on Mars they first need to find water. And in the absence of water, they have tried to see what happens when they introduce it onto the planet.
