Audio recordings of local whirlwinds provide data on Mars weather, wear and tear of space hardware
Audio data recorded by a NASA rover has, for the first time, allowed earthbound humans to hear the sound of a dust devil passing on the Martian surface.
Dust devils, whirlwinds which draw up dust from the surface, were first recorded on Mars in the 1970s by Viking orbiters. The 1990s Mars Pathfinder lander detected a dust devil passing over it, and animation of dust devils were recorded by NASA's Spirit, Curiosity and Perseverance rovers.However, the sound of a Martian dust devil was inaccessible until Perseverance rover's SuperCam microphone recordings were published.
Analysis of multi-sensor data and modelling by a group led by Naomi Murdoch, faculty researcher at France's École nationale supérieure de l'aéronautique et de l'espace, suggests the dust devil stood at over 118 meters tall. The researchers said the findings could improve understanding of surface changes, dust storms and climate variability on Mars, which may have implications for space exploration.
But the recording, which readers can hear in the embedded video, resulted from the unexpected encounter with the meteorological features passing directly over NASA's space hardware.

Boston Requires Captions on TVs in Restaurants, Banks, GymsRestaurants, bars, banks, gyms, and other public venues in Boston with televisions are now required to turn on the closed-captioning function to increase access for people with disabilities. Mayor Michelle Wu signed a City-Council passed ordinance on Friday. She said improving communications access in public spaces across Boston is critical to Boston truly being for everyone. The advisory board to the city’s disabilities commission raised the issue of requiring that live transcripts of a program’s audio content be shown scrolling across the bottom of the screen. During the height of the COVID-19 pandemic, TV stations broadcasted municipal press conferences, and other information that wasn’t available to the deaf community and people with hearing disabilities.
