NASA: Mars 2020 - Next Generation Rover

Next Mars Rover Will Have 23 'Eyes'
NASA | JPL-Caltech | Mars 2020 | 2017 Oct 31
[img3="A selection of the 23 cameras on NASA's 2020 Mars rover. Many are improved versions of the cameras on the Curiosity rover, with a few new additions as well. UPDATED AT 4:15 p.m. PDT to correct the number of EDL cameras shown in the image.

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. ...

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

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.

Mars2020: A Piece of Mars Is Going Home

Post by bystander » Wed Feb 14, 2018 4:32 pm

A Piece of Mars Is Going Home
NASA | JPL-Caltech | Mars 2020 | 2018 Feb 13
A chunk of Mars will soon be returning home.

A piece of a meteorite called Sayh al Uhaymir 008 (SaU008) will be carried on board NASA’s Mars 2020 rover mission, now being built at the agency’s Jet Propulsion Laboratory in Pasadena, California. This chunk will serve as target practice for a high-precision laser on the rover’s arm.

Mars 2020’s goal is ambitious: collect samples from the Red Planet’s surface that a future mission could potentially return to Earth. One of the rover’s many tools will be a laser designed to illuminate rock features as fine as a human hair.

That level of precision requires a calibration target to help tweak the laser’s settings. Previous NASA rovers have included calibration targets as well. Depending on the instrument, the target material can include things like rock, metal or glass, and can often look like a painter’s palette.

But working on this particular instrument sparked an idea among JPL scientists: why not use an actual piece of Mars? Earth has a limited supply of Martian meteorites, which scientists determined were blasted off Mars’ surface millions of years ago.

These meteorites aren’t as unique as the geologically diverse samples 2020 will collect. But they’re still scientifically interesting -- and perfect for target practice. ...

Mars 2020 Reaches Key Manufacturing Milestone

Post by bystander » Fri Mar 16, 2018 6:44 pm

Next NASA Mars Rover Reaches Key Manufacturing Milestone
NASA | JPL-Caltech | Mars 2020 | 2018 Mar 13
NASA's Mars 2020 mission has begun the assembly, test and launch operations (ATLO) phase of its development, on track for a July 2020 launch to Mars.

The first planned ATLO activities will involve electrical integration of flight hardware into the mission's descent stage. The Mars 2020 rover, as well as its cruise stage, aeroshell and descent stage -- a rocket-powered "sky crane" that will lower the rover to the planet's surface -- will undergo final assembly at the Spacecraft Assembly Facility High Bay 1 at NASA's Jet Propulsion Laboratory in Pasadena, California. ...

Over the next year-and-a-half, engineers and technicians will add subsystems such as avionics, power, telecommunications, mechanisms, thermal systems and navigation systems onto the spacecraft. The propulsion systems were installed earlier this year on the cruise and descent stage main structures. ...
