NASA’s Perseverance rover set to begin third year at Jezero Crater

After finishing the primary pattern depot on one other world, the rover continues its hunt for Mars rocks worthy of examine on Earth.

NASA’s Perseverance rover will have fun its second anniversary on the floor of Mars Saturday, Feb. 18. Since arriving at Jezero Crater in 2021, the six-wheeled, nuclear-powered rover has been inspecting geologic options and accumulating samples of the Pink Planet which are central to step one of the NASA-ESA (European House Company) Mars Pattern Return marketing campaign.

Scientists wish to examine Martian samples with highly effective lab gear on Earth to seek for indicators of historical microbial life and to raised perceive the processes which have formed the floor of Mars.

“Anniversaries are a time of reflection and celebration, and the Perseverance workforce is doing lots of each,” mentioned Perseverance challenge scientist Ken Farley of Caltech in Pasadena.

“Perseverance has inspected and carried out data collection on tons of of intriguing geologic features, collected 15 rock cores, and created the primary pattern depot on one other world. With the beginning of the subsequent science marketing campaign, generally known as ‘Higher Fan,’ on Feb. 15, we count on to be including to that tally very quickly.”

Along with the rock cores, Perseverance has collected two regolith samples and one atmospheric pattern, and it has sealed three “witness” tubes. (Study extra about all 18 samples taken thus far.)

Numbers play an enormous position within the lifetime of a Mars rover mission, not simply because the workforce contains a powerful amount of scientists (who do not normally thoughts numbers) and engineers (who love them), however as a result of statistics present the perfect and most effective glimpse of car tendencies and efficiency.

For example, the mission can let you know not solely that the rover has pushed 9.3 miles (14.97 kilometers), but additionally that as of Feb. 14, its left entrance wheel has carried out 9,423 revolutions. They will let you know not solely that the MOXIE (quick for Mars Oxygen In-Situ Useful resource Utilization Experiment) know-how demonstration has produced 3.25 ounces (92.11 grams) of oxygen, but additionally that the Fuel Mud Removing Instrument (gDRT)—the little gas-puffing gadget on the robotic arm—has puffed 62 instances to clear residual dust and particles from rock-abrading actions.

“We cope with lots of numbers,” mentioned Perseverance deputy challenge supervisor Steve Lee from NASA’s Jet Propulsion Laboratory in Southern California. “We gather them, consider them, examine them, and extra instances than we wish to admit, bore our family members with them throughout a household dinner.”

With that, listed below are some essentially the most up-to-date statistics relating to Perseverance’s first two Earth years of Jezero floor operations. Some will appear obscure, whereas others are extra instant, however all of them underscore how productive the mission has been.

Perseverance science statistics

The rover carries seven science instruments, they usually’ve been busy.

• Laser photographs fired by the SuperCam science instrument: 230,554
• Soundings carried out by the RIMFAX (Radar Imager for Mars’ Subsurface Experiment) ground-penetrating radar to review underground rock layers: 676,828
• Mars audio recordings taken by SuperCam’s microphone: 662
• Hours of Mars climate knowledge recorded by MEDA (Mars Environmental Dynamics Analyzer): 15,769.1
• Hours the X-ray filament on the PIXL (Planetary Instrument for X-ray Lithochemistry) instrument has operated: 298.2
• Laser photographs by the SHERLOC (Scanning Liveable Environments with Raman & Luminescence for Organics & Chemical substances) instrument: 4,337,010
• SHERLOC spectroscopy observations: 33

Perseverance mobility and operational statistics

Together with the large drill-toting robotic arm, the rover has a small pattern dealing with arm inside its stomach.

• Instances the rover’s major robotic arm has been unstowed and stowed: 64
• Instances the drill on that arm has touched Mars: 39
• Instances drill bits have been exchanged: 48
• Abrasions carried out by the drill: 17
• Distance the rover’s pattern dealing with arm’s z-stage has traveled up and down: 676.1 ft (206.1 meters)

Perseverance digicam statistics

Perseverance packs seven science cameras together with 9 engineering cameras. Collectively, these cameras have taken greater than 166,000 photographs. Listed here are the picture tallies for a number of of them.

• Mastcam-Z: 86,660
• Navigation Cameras: 21,571
• Entrance Hazard-Avoidance Cameras: 3,909
• Rear Hazard-Avoidance Cameras: 474
• Sampling and Caching System Digicam:1,321
• SuperCam Distant Micro-Imager: 2,825
• SHERLOC WATSON: 5,754
• SHERLOC Context Imager: 2,260
• MEDA SkyCam: 1,831
• PIXL Micro-Context Digicam: 1,012
• Entry, Descent, and Touchdown Cameras: 33,279

“Behind every quantity is lots of thought and energy from a really gifted group of ladies and men on the Perseverance workforce,” mentioned Artwork Thompson, Perseverance challenge supervisor at JPL. “We now have come a good distance collectively, and I can not consider a greater group to work with as we go even farther.”

In reality, when Perseverance marks its second touchdown anniversary, Mars can be 97 million miles (156 million kilometers) from Earth. The climate at Jezero Crater is anticipated to be sunny with a excessive of about 7 levels Fahrenheit (minus 14 levels Celsius).

The rover has directions to carry out distant science and take photographs of a spot in Jezero Crater referred to as “Jenkins Hole.” And folks on the mission workforce are anticipated to take at the very least one second to recall the place they had been and the way they felt two years in the past, when Perseverance landed on Mars.
