Hear sounds from Mars captured by NASA's Perseverance rover | Space

NASA's Perseverance rover has recorded up to five hours of sounds on the Mars, giving engineers a sense of how the Red Planet sounds different from Earth.

"It's like you're really standing there," Baptiste Chide, a planetary scientist who studies data from the Perseverance microphones, said in a statement from NASA's Jet Propulsion Laboratory (JPL).

Watch NASA's Perseverance rover zoom across Mars' rocky, alien landscape - CNET

If you were a rover on Mars, this would be your view. The landscape is part of what Perseverance saw during a Sept. 12 AutoNav drive.

The video is nifty for the perspective and the fabulous views of Mars, but it's also special for what it shows us about how the rover gets around. NASA's latest and fanciest rover is equipped with an auto-navigation system called AutoNav.

Spacecraft spots mesmerizing swirls at one of the lowest points on Mars - CNET

Try to comprehend the scale of the Hellas impact basin on Mars. At 1,430 miles (2,300 kilometers) in diameter and 4.3 miles (7 kilometers) deep, it's a doozy of a crater, one of the largest we know of in the solar system.

On Friday, the European Space Agency shared a view snapped by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter back in May. It shows a wild wonderland of swirls and curves the space agency described as "mesmerizing."

The Mars helicopter Ingenuity is ready to fly again after interplanetary radio blackout | Space

NASA's Mars helicopter is ready to make its first flight attempt after a two-week communications blackout caused by the sun's being directly between Earth and the Red Planet.

The Ingenuity helicopter, a technology demonstration drone that was supposed to fly at most five times within a month, has instead flown 13 successful sorties to date, accompanying the car-sized Perseverance rover on its explorations of their Jezero Crater landing site.

Cyprus aims for Mars with X-Ray rock dating instrument

NICOSIA, Cyprus (AP) — Tiny Cyprus aims to join the global space exploration drive by developing a compact, X-Ray instrument capable of dating Martian soil and rock samples relatively accurately to potentially reveal more about the Red Planet's geological history and offer a glimpse of Earth's

Sols 3272-3273: Emerging From the Shadows... – NASA's Mars Exploration Program

Curiosity went into hibernation for a few weeks, executing only routine environmental and radiation monitoring activities, while the Sun was positioned between us and Mars (conjunction). Today is our first day planning since Mars has emerged from behind the sun.

Prior to conjunction, Curiosity drove away from the Maria Gordon drill site to an area nearby that contained large (~6-7 cm across) resistant nodules (“Helmsdale Boulder Beds”).

Mars could host a deep underground biosphere - Sciworthy

One of the water-rock reactions that subsurface microorganisms rely on is called radiolysis . Radiolysis occurs when naturally found radioactive minerals within rocks break down and release small amounts of radiation. This radiation breaks apart nearby water molecules.

Scientists have known that Mars has some subsurface water for several decades, but they don't know how much. Using rover and orbiter data showing the densities of different martian rocks, the team estimated the amount of water that might be there. Why would rock densities matter?
