Re: New 2020 Mars Rover based on MSL

The scientists are apparently intrigued by those rocks close to the rover wheels. Full of holes like a Swiss cheese. Could be indicative of life.

It's weird how this mission is so "life-friendly" unlike all previous missions. NASA have had 50 years to put life-finder tech on Mars and have signally failed to do so.

Excuse my paranoia but it would make sense for NASA to now provide "findings of life" evidence to the UN planetary protection mob who can then use it to lobby against human missions to Mars.

The Radar Imager for Mars’ Subsurface Experiment (RIMFAX) is a Ground Penetrating Radar on the Mars 2020 mission’s Perseverance rover, which is planned to land near a deltaic landform in Jezero crater. RIMFAX will add a new dimension to rover investigations of Mars by providing the capability to image the shallow subsurface beneath the rover.

In the meantime, new pictures from the rover's dramatic descent and possibly video are expected by Monday when NASA plans another news briefing.

you can see the dust kicked up by the crane engines firing

Re: New 2020 Mars Rover based on MSL

Mars rover travels 6.5 metres in ‘flawless’ first driveBB1ei6jI.img?h=599&w=799&m=6&q=60&o=f&l=f

Does not seem like much but its a start...

Taking directions from mission managers at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles, the rover rolled four metres (13.1 feet) forward, turned about 150 degrees to its left and then drove backwards another 2.5 meters (8.2 feet) for a total of 6.5 metres (21.3 feet) during its half-hour test within Jezero Crater, site of an ancient, long-vanished lake bed and river delta on Mars.

We finally know how NASA is going to get its Mars samples back

Northrop Grumman’s selection for new projects have been costly in the past....

Re: New 2020 Mars Rover based on MSL

This is a follow up
NASA Awards Mars Ascent Propulsion System Contract for Sample Return

The cost-plus, fixed-fee contract has a potential mission services value of $60.2 million and a maximum potential value of $84.5 million. Work on MAPS begins immediately with a 14-month base period, followed by two option periods that may be exercised at NASA's discretion.

https://www.jpl.nasa.gov/missions/mars- … return-msr

Coupled with the successful touchdown of the Mars Perseverance rover, this award moves NASA and ESA (European Space Agency) one step closer to realizing Mars Sample Return (MSR), a highly ambitious planetary exploration program that will build upon decades of science, knowledge, and experience of Mars exploration.

This seems more in Northrup Grumman's wheel house to achieve at cost...

Re: New 2020 Mars Rover based on MSL

Locally named features being chosen to honor the Navajo Nation first by NASA names new features on Mars in Navajo language

BB1ewqTP.img?h=450&w=799&m=6&q=60&o=f&l=f

Scientists on the team say that they welcome the chance to learn Navajo words and their meaning.
The Perseverance team has a list of 50 names to start with for future uncovered terrain. The team will continue to work with the Navajo Nation on more names as the rover further explores the red planet.

"Tséwózí bee hazhmeezh," which means "Rolling rows of pebbles, like waves"
"Bidziil," which means "strength"
"Hoł nilį́," which means "respect"
"Ha'ahóni," meaning "perseverance"

Listed in the article are these others
"Máaz," the Navajo word for "Mars."

The spot where the rover landed has been named "Tséyi," for Arizona's Canyon de Chelly National Monument, located in the heart of Navajo Nation.

Re: New 2020 Mars Rover based on MSL

one experiment down and another is now ready to go NASA's Perseverance rover just turned CO2 into oxygen. The technology could help future astronauts breathe on Mars.

5.4 grams, enough to keep an astronaut healthy for 10 minutes

Re: New 2020 Mars Rover based on MSL

Perseverance Rover will peer beneath Mars' surface12-perseverance.jpg
RIMFAX will be the first ground-penetrating radar set on the surface of Mars.

Short for Radar Imager for Mars' Subsurface Experiment, RIMFAX can provide a highly detailed view of subsurface structures down to at least 30 feet (10 meters) underground. In doing so, the instrument will reveal hidden layers of geology and help find clues to past environments on Mars, especially those that may have provided the conditions necessary for supporting life.

Perseverance rover travels at a top speed of less than 0.1 miles per hour.

Wow I think the tortoise just pasted the rover... nah never mind...

Re: New 2020 Mars Rover based on MSL

I greatly enjoyed the many images in the article Mars_B4_Moon...

Nasa is caught between the old contractors and the upstarts that are not following all the same rules of test, production that the old guard are using.

The failures would not be tolerated if it was not for the low cost to begin with....

JPL built a copy of the Perseverance; a twin rover used for testing and problem solving, OPTIMISM (Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars), a vehicle system test bed (VSTB). It is housed at the JPL Mars Yard and is used to test operational procedures and to aid in problem solving should any issues arise with Perseverance




Perseverance heavier, weighing 1,025 kg (2,260 lb) compared to Curiosity at 899 kg (1,982 lb)—a 14% increase.

Sky crane
fueled cruise stage (539 kg)

8 × MR-80B (skycrane)
The descent stage is a platform above the rover with eight variable thrust monopropellant hydrazine rocket thrusters on arms extending around this platform to slow the descent. Each rocket thruster, called a Mars Lander Engine (MLE), produces 400 to 3,100 N

The spacecraft has a launch weight 3839 kg consisting of the 899 kg rover, the 2401 kg EDL System (Aeroshell and fueled descent stage), including 390 kg of landing propellant and the 539 kg fueled cruise stage.
