    In this image, taken on June 21, 2019, engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, install the main robotic arm on the Mars 2020 rover. (A smaller arm to handle Mars samples will be installed inside the rover as well.) The main arm includes five electrical motors and five joints (known as the shoulder azimuth joint, shoulder elevation joint, elbow joint, wrist joint and turret joint). Measuring 7 feet (2.1 meters) long, the arm will allow the rover to work as a human geologist would: by holding and using science tools with its turret, which is essentially its "hand."

    "You have to give a hand to our rover arm installation team," said Ryan van Schilifgaarde, a support engineer at JPL for Mars 2020 assembly. "They made an extremely intricate operation look easy. We're looking forward to more of the same when the arm will receive its turret in the next few weeks."

    It's based on Curiosity, so presumably the same sort of Sky-Crane.

    "Mars 2020 Rover Gets a Super Instrument"

    http://www.marsdaily.com/reports/Mar...ument_999.html

    Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, have installed the SuperCam Mast Unit onto the Mars 2020 rover. The instrument's camera, laser and spectrometers can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (6 meters).

    SuperCam is a next-generation version of the ChemCam instrument operating on NASA's Curiosity Mars rover. It has been developed jointly in the U.S., France and Spain. Once France delivered the last piece of flight hardware, the instrument was fully integrated on the Mars 2020 rover on June 25, 2019, in the Spacecraft Assembly Facility's High Bay 1 clean room at JPL.

    "SuperCam has come a long way from being a bold and ambitious idea to an actual instrument," said Sylvestre Maurice, the SuperCam deputy principal investigator at the Institut de Recherche en Astrophysique et Planetologie in Toulouse, France. "While it still has a long way to go - all the way to Mars - this is a great day for not only SuperCam but the amazing consortium that put it together."

    Mars 2020 scientists will use SuperCam to examine Martian rocks and soil, seeking organic compounds that could be related to past life on Mars.

    "Mars 2020 Rover almost Assembled"

    http://www.planetary.org/blogs/jason...assembled.html

    NASA last week said that major assembly of the Mars 2020 rover is complete, after technicians installed the carousel that holds the tools that will be used to collect samples for future return to Earth. The rover, which is being assembled and tested at NASA's Jet Propulsion Laboratory (you can watch live video from the Spacecraft Assembly Facility here), already has its wheels, mast, and science instruments installed. The helicopter drone has also been attached. Launch remains on track for the start of a window that lasts from 17 July to 5 August 2020.

    "NASA's Mars Helicopter Attached to Mars 2020 Rover"

    http://www.marsdaily.com/reports/NAS...Rover_999.html

    Engineers attached NASA's Mars Helicopter, which will be the first aircraft to fly on another planet, to the belly of the Mars 2020 rover in the High Bay 1 clean room at the Jet Propulsion Laboratory in Pasadena, California.

    The twin-rotor, solar-powered helicopter was connected, along with the Mars Helicopter Delivery System, to a plate on the rover's belly that includes a cover to shield the helicopter from debris during entry, descent and landing. The helicopter will remain encapsulated after landing, deploying to the surface once a suitable area to conduct test flights is found at Jezero Crater, the rover's destination.

    The contest has been announced.

    http://www.marsdaily.com/reports/NAS...Rover_999.html

    Red rover, red rover, send a name for Mars 2020 right over! NASA is recruiting help from students nationwide to find a name for its next Mars rover mission.

    Starting Tuesday, K-12 students in U.S. public, private and home schools can enter the Mars 2020 Name the Rover essay contest. One grand prize winner will name the rover and be invited to see the spacecraft launch in July 2020 from Cape Canaveral Air Force Station in Florida.

    The Name the Rover contest is part of NASA's efforts to engage students in the STEM enterprise behind Mars exploration and inspire interest in science, technology, engineering and mathematics.

    K-12. Hmmm. Fortunately the name "Boaty McBoatface" is already taken. But I wonder about "Barbie's Dream Rover"?

    We have a name "Perseverance"

    http://www.collectspace.com/news/new...severance.html

    When NASA's next rover extends its robotic arm on Mars next year, it will do so with "Perseverance," thanks to the contest entry of a 13-year-old student from Virginia.

    Now attached to the arm is a laser-inscribed plate displaying "Perseverance" as the rover's newly-revealed name. The six wheeled science platform was known previously as NASA's Mars 2020 rover.

    "Like every exploration mission before, our rover is going to face challenges, and it's going to make amazing discoveries. It's already surmounted many obstacles to get us to the point where we are today — processing for launch," said Thomas Zurbuchen, NASA's associate administrator for science. "That inspiring work will always require perseverance. We can't wait to see that nameplate on Mars."

    "How NASA's Mars Helicopter Will Reach the Red Planet's Surface"

    https://www.marsdaily.com/reports/Ho...rface_999.html

    NASA's Ingenuity Mars Helicopter will travel with the Perseverance rover through 314 million miles (505 million kilometers) of interplanetary space to get to Mars. But for the team working on the first experimental flight test on another planet, engineering the final 5 inches (13 centimeters) of the journey has been among the most challenging of all. To safely navigate those 5 inches - the distance Ingenuity will travel from where it's stowed on the rover to the surface of Mars - they came up with the ingenious Mars Helicopter Delivery System.

    "Ingenuity is unlike any other helicopter ever built because powered controlled flight at Mars is unlike anything ever attempted," said MiMi Aung, project manager of the Mars Helicopter at NASA's Jet Propulsion Laboratory in Southern California. "And then we had to figure out how to hitch a ride and safely get deployed from the Mars 2020 Perseverance rover."

    "6 Things to Know About NASA's Ingenuity Mars Helicopter"

    https://www.jpl.nasa.gov/news/news.php?feature=7703

    When NASA's Mars 2020 Perseverance rover launches from Cape Canaveral Air Force Station in Florida later this summer, an innovative experiment will ride along: the Ingenuity Mars Helicopter. Ingenuity may weigh only about 4 pounds (1.8 kilograms), but it has some outsize ambitions.

    "The Wright Brothers showed that powered flight in Earth's atmosphere was possible, using an experimental aircraft," said Håvard Grip, Ingenuity's chief pilot at NASA's Jet Propulsion Laboratory in Southern California. "With Ingenuity, we're trying to do the same for Mars."

    "Mars and the year of Perseverance"

    https://thehill.com/opinion/technolo...f-perseverance

    Later this month, the Perseverance rover begins a seven-month voyage to Mars in what will be a vital precursor to human missions in the 2030s. When the name “Perseverance” was chosen for the 2020 Mars rover earlier this year, few would have predicted how apt that name would become in these difficult times. Since then, the nation and the world have been enduring unprecedented challenges from an ongoing worldwide pandemic to massive economic disruptions and a seismic realignment of perceptions of racism.

    "Perseverance Microphones Fulfill Long Planetary Society Campaign to Hear Sounds from Mars"

    https://www.planetary.org/blogs/pers...-tps-mics.html

    If you could stand on the surface of Mars, what would you hear? While 8 missions have returned stunning views from the surface of the Red Planet, none have returned any sound.

    That’s about to change. NASA’s Perseverance rover, which is days away from blasting off on a mission to search for signs of past life and collect samples for future return to Earth, will have not one, but two microphones aboard. One will listen as the rover plummets through the Martian atmosphere for landing, and another will record sounds as the rover does its scientific work in Jezero Crater—an ancient river delta where life may have flourished.

    If all goes well, Perseverance’s microphones will fulfill the wishes of Planetary Society co-founder Carl Sagan, who wrote a letter to NASA in 1996 urging the space agency to send a microphone to Mars.

    "Even if only a few minutes of Martian sounds are recorded from this first experiment, the public interest will be high and the opportunity for scientific exploration real," Sagan wrote.

    Successful launch so far and awaiting the second burn of the Centaur upper stage. Right now it’s just drifting in a parking orbit.

    Pretty Cool! What's the life expectancy of the little 4 lb chopper? Does it have solar cells for recharging in flight? Can it land and then take off again, or once in flight it's up until it runs out of power? Thx for any insights.

    Here’s the press kit which includes a section on Ingenuity. The drone is designed to last at least a month but it seems that the designers have fairly low expectations since it’s considered to be a technology experiment, like Sojourner . First job though is to survive the cold Martian nights before it’s ready to deploy.

    Thanks for that link/info schlaugh, you & it gave me answers...

    - Surviving launch from Cape Canaveral, the cruise to Mars and landing on the Red Planet
    - Safely deploying to the surface from the belly pan of the Perseverance rover
    - Autonomously keeping warm through the intensely cold Martian nights
    - Autonomously charging itself with its solar panel
    And then, if Ingenuity succeeds in its first flight, the helicopter team will attempt up to four other test flights
    within a 30-Martian-day (31-Earth-day) window

    "Mars 2020 spacecraft resumes normal operations after post-launch safe mode"

    https://spaceflightnow.com/2020/07/3...nch-safe-mode/

    NASA’s Mars 2020 Perseverance mission resumed normal operations Friday after cold temperatures forced the spacecraft into safe mode soon after a successful launch from Cape Canaveral.

    “With safe mode exit, the team is getting down to the business of interplanetary cruise,” said Matt Wallace, the Mars 2020 mission’s deputy project manager at NASA’s Jet Propulsion Laboratory.

    “Next stop, Jezero Crater,” he added, referring to the Perseverance rover’s landing site on Mars.

    "Ingenuity Mars Helicopter recharges"

    https://www.marsdaily.com/reports/In...light_999.html

    NASA's Ingenuity Mars Helicopter received a checkout and recharge of its power system on Friday, Aug. 7, one week into its near seven-month journey to Mars with the Perseverance rover. This marks the first time the helicopter has been powered up and its batteries have been charged in the space environment.

    During the eight-hour operation, the performance of the rotorcraft's six lithium-ion batteries was analyzed as the team brought their charge level up to 35%. The project has determined a low charge state is optimal for battery health during the cruise to Mars.
