NASA Recruits Mars Perseverance Rover to Monitor Solar’s Exercise
Mars is passing behind the solar, giving NASA’s Perseverance rover a view of the star’s far facet
NASA has drafted its Mars rover Perseverance to assist monitor the solar’s exercise. Day-after-day for the following two months, the rover will picture the solar with its Mastcam-Z cameras, capturing essential details about sunspots and different giant options that can provide clues to photo voltaic exercise.
Mars is at present passing behind the solar, giving the rover a view of the star’s far facet—a perspective we are able to’t see from Earth. Perseverance’s Mastcam-Z, which consists of zoomable cameras hooked up to its mast, isn’t designed for photo voltaic monitoring; the rover factors the system on the solar as soon as a day to measure the mud within the Martian air, vital info for climate forecasting on the Pink Planet. However it’s delicate sufficient to see giant sunspots.

This isn’t the primary time NASA has recruited Perseverance as a photo voltaic observatory—the company additionally used the rover to picture sunspots in 2024.
Sunspots are non permanent darkish areas on the solar that happen when intense magnetic fields block out warmth from the inside of the solar. Concentrated in energetic areas, they’ll final days or months and usually coincide with different phenomena corresponding to photo voltaic flares and coronal mass ejections. If these energetic explosions are pointed towards Earth, they’ll trigger auroras and even disruptions to satellite tv for pc and radio techniques.
It’s Time to Stand Up for Science
In case you loved this text, I’d prefer to ask to your help. Scientific American has served as an advocate for science and trade for 180 years, and proper now could be the most important second in that two-century historical past.
I’ve been a Scientific American subscriber since I used to be 12 years previous, and it helped form the way in which I have a look at the world. SciAm at all times educates and delights me, and conjures up a way of awe for our huge, stunning universe. I hope it does that for you, too.
In case you subscribe to Scientific American, you assist be certain that our protection is centered on significant analysis and discovery; that now we have the assets to report on the selections that threaten labs throughout the U.S.; and that we help each budding and dealing scientists at a time when the worth of science itself too typically goes unrecognized.
In return, you get important information, charming podcasts, sensible infographics, can’t-miss newsletters, must-watch movies, difficult video games, and the science world’s finest writing and reporting. You possibly can even present somebody a subscription.
There has by no means been a extra essential time for us to face up and present why science issues. I hope you’ll help us in that mission.
