NASA: Mars 2020 - Next Generation Rover

Next Mars Rover Will Have 23 'Eyes'
NASA | JPL-Caltech | Mars 2020 | 2017 Oct 31

When NASA's Mars Pathfinder touched down in 1997, it had five cameras: two on a mast that popped up from the lander, and three on NASA's first rover, Sojourner.

Since then, camera technology has taken a quantum leap. Photo sensors that were improved by the space program have become commercially ubiquitous. Cameras have shrunk in size, increased in quality and are now carried in every cellphone and laptop.

That same evolution has returned to space. NASA's Mars 2020 mission will have more "eyes" than any rover before it: a grand total of 23, to create sweeping panoramas, reveal obstacles, study the atmosphere, and assist science instruments. They will provide dramatic views during the rover's descent to Mars and be the first to capture images of a parachute as it opens on another planet. There will even be a camera inside the rover's body, which will study samples as they're stored and left on the surface for collection by a future mission.

All these cameras will be incorporated as the Mars 2020 rover is built at NASA's Jet Propulsion Laboratory in Pasadena, California. They represent a steady progression since Pathfinder: after that mission, the Spirit and Opportunity rovers were designed with 10 cameras each, including on their landers; Mars Science Laboratory's Curiosity rover has 17. ...

23 'Eyes' but no 'Ears'

A new hope for a microphone on Mars: Enhancing Mars 2020 science with sound
Bruce Betts & Emily Lakdawalla • February 15, 2016

<<When the Mars 2020 rover lands, we may finally hear the first audio recordings from the Martian surface. The Planetary Society has been working for decades to land a Mars Microphone, something that would add a second human sense to the amazing imagery we currently get, and would be very engaging and exciting for not only scientists, but also for the general public. Unfortunately, the only two such instruments to have launched suffered sad fates. The first Planetary Society Mars Microphone crashed with Mars Polar Lander. The second microphone to fly to Mars, on Phoenix, was never turned on because of the potential for an electronic problem. The payload of the ExoMars 2018 rover may include infrasound and pressure sensors that could produce sound-like recordings. In an abstract submitted to the 2016 Lunar and Planetary Science Conference (PDF), members of the Mars 2020 SuperCam team explain how including a microphone on their instrument could support their science -- and record sounds on Mars.

Sylvestre Maurice and his coauthors explain in the abstract that the microphone would be useful both for science and engineering. As with various past proposed and flight Mars microphones, sound in principle could serve as an independent constraint on wind speed, and could help identify the passing of dust devils. The microphone would also record all the various noises made by the rover: the whirr of the actuators, the crunch of the wheels across the ground, the pumps that keep the rover's Freon circulating. And the wind itself would create its own sound, whistling past the rover's various protuberances.>>

Can they also add the ability for it to "bark" ?
Then it would be the first one worthy of the name "Rover".

NASA Builds its Next Mars Rover Mission - Mars 2020

NASA Builds its Next Mars Rover Mission
NASA | JPL-Caltech | Mars 2020 | 2017 Nov 28

Click to play embedded YouTube video.
In just a few years, NASA's next Mars rover mission will be flying to the Red Planet.

At a glance, it looks a lot like its predecessor, the Curiosity Mars rover. But there's no doubt it's a souped-up science machine: It has seven new instruments, redesigned wheels and more autonomy. A drill will capture rock cores, while a caching system with a miniature robotic arm will seal up these samples. Then, they'll be deposited on the Martian surface for possible pickup by a future mission.

This new hardware is being developed at NASA's Jet Propulsion Laboratory, Pasadena, California, which manages the mission for the agency. It includes the Mars 2020 mission's cruise stage, which will fly the rover through space, and the descent stage, a rocket-powered "sky crane" that will lower it to the planet's surface. Both of these stages have recently moved into JPL's Spacecraft Assembly Facility.

Mars 2020 relies heavily on the system designs and spare hardware previously created for Mars Science Laboratory's Curiosity rover, which landed in 2012. Roughly 85 percent of the new rover's mass is based on this "heritage hardware." ...

Not such a silly thought .. sound can often be more important than sight .. in attracting the curiosity of life forms one example.

And that will be the Mars Rover Pooper-Scooper Mission?
