Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of ancient life on the red planet may not be sensitive enough to make accurate assessments, according to an ...
The ongoing search for signs of life on Mars relies in part on terrestrial analogs – places on Earth closely resembling the past or current geology and climate of the red planet that can be readily ex...
The eerie sound of an extraterrestrial whirlwind has reached the Earth from more than 50 million miles away, thanks to the first working microphone to traverse the surface of Mars. The audio records t...
