Perseverance Mars rover wind sensor damaged by pebbles, but still operational

Higher-than-anticipated breeze speeds struck components on the Red Planet meanderer's weather conditions station.

Mars can be a terribly blustery spot, it ends up.

The Perseverance wanderer landed on the Red Planet in February 2021 conveying, among different instruments, a weather conditions station named Mars Environmental Dynamics Analyzer (MEDA). That instrument incorporates two breeze sensors that action speed and bearing, among a few different sensors that give climate measurements like dampness, radiation and air temperature.

Rocks conveyed overhead areas of strength for by Planet blasts as of late harmed one of the breeze sensors, yet MEDA can in any case monitor wind at its arrival region in Jezero Crater, though with diminished awareness, José Antonio Rodriguez Manfredi, head agent of MEDA, told Space.com.

"This moment, the sensor is decreased in its capacities, yet it actually gives speed and course sizes," Rodriguez Manfredi, a researcher at the Spanish Astrobiology Center in Madrid, wrote in an email. "The entire group is presently re-tuning the recovery system to get additional exactness from the unharmed identifier readings."

The two roughly ruler-sized breeze sensors on Perseverance are encompassed by six individual locators that mean to provide precise readings from any guidance, as per materials(opens in new tab) from NASA's Jet Propulsion Laboratory in California, which deals with the wanderer.

Every one of the two principal wind sensors is connected to a blast that can unfurl to move the sensors from the wanderer as it drives, on the grounds that the vehicle estimated Perseverance influences wind flows by its own developments through the dainty Martian environment, JPL authorities expressed.

Like all instruments on Perseverance, the wind sensor was designed with redundancy and protection in mind, Rodriguez Manfredi noted. "But of course, there is a limit to everything."

And for an instrument like MEDA, the limit is more challenging, since the sensors must be exposed to environmental conditions in order to record wind parameters. But when stronger-than-anticipated winds lifted larger pebbles than expected, the combination resulted in damage to some of the detector elements.

"Neither the predictions nor the experience we had from previous missions foresaw such strong winds, nor so much loose material of that nature," Rodriguez Manfredi said. (He is also principal investigator of another temperature and wind sensor on the NASA InSight lander, on the Red Planet since November 2018 and expected to end its mission this year.)

He added it was was ironic that the sensors were damaged by wind, or "precisely by what we went looking for."

Perseverance landed on Mars on Feb. 18, 2021, and, along with a helicopter called Ingenuity, is exploring an ancient river delta that may have been rich in microbes billions of years ago.

Besides measuring wind, weather and rock composition, the rover is picking up the most promising material to cache for a future sample return-mission aiming to send samples to Earth in the 2030s.
