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 foun...

In fact, NASA has massaged the audio sample above to help listeners hear Ingenuity. Sounds below 80Hz and above 90Hz have been turned down in volume so that the 84Hz hum of the tiny computer-controlled craft's rotors can be heard. A small team at mission control has been experimenting with Ingenuity’s limits for about a month. Over that time, the small autonomous aircraft has performed a series of flights at increasing heights and speeds. The flight data is uploaded to Perseverance and sent back to Earth for the team to study, and the video above is taken from Ingenuity’s fourth flight wh...

Mars rover captures first sounds recorded on another planet Sophie Lewis © NASA/JPL-Caltech 022221-rover1.jpg NASA's Perseverance rover, which landed on Mars less than one week ago, has beamed back the first-ever audio recordings from the surface of the red planet. NASA released the audio clips Monday, along with never-before-seen video footage of the rover landing last Thursday, and the most sophisticated images yet taken of Mars. Along with 25 onboard cameras, the rover also carries two microphones. One failed to work during the rover's descent, but the other captured the...

While numerous missions have returned photos from Mars, none have captured any sound from the Red Planet million of miles away.

You'll want to use your headphones for these clips.
