NASA has released audio recorded by one of Perseverance’s microphones as the rover completed one of its earliest drives.
NASA released two versions of the audio — one 90-second file edited and processed to filter out background noise, and another 16-minute clip with raw, unfiltered sound.
…Perseverance recorded the sounds during a 90-foot (27.3-meter) drive March 7, according to NASA. The rover’s top speed is a little less than 0.1 mph, or about 152 meters per hour.
The longer, raw audio clip includes a high-pitched scratching noise. The origin of the sound remains a mystery. “Perseverance’s engineering team continues to evaluate the source of the scratching noise, which may either be electromagnetic interference from one of the rover’s electronics boxes or interactions between the mobility system and the Martian surface,” NASA said in a statement. “The EDL microphone was not intended for surface operations and had limited testing in this configuration before launch.”

In addition, the science team has picked the location where Perseverance will deploy the Ingenuity helicopter. A briefing will be held next week on March 23rd to outline the schedule for its test flight, now set for sometime in early April.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
