Explanation:
What's the sound of
one laser zapping?
There's no need to consult a Zen master to find out,
just listen to the first
acoustic recording of laser shots on Mars.
On
Mars Rover Perseverance
mission sol 12 (March 2, 2021) the SuperCam instrument atop
the rover's mast zapped a rock dubbed Ma'az 30 times from a range of
about 3.1 meters.
Its microphone
recorded the soft staccato popping sounds of the
rapid series of SuperCam laser zaps.
Shockwaves created in the thin Martian atmosphere as bits
of rock are vaporized by the laser shots make the popping sounds,
sounds that offer clues to the physical structure of the target.
This SuperCam close-up
of the Ma'az target region is 6 centimeters (2.3 inches) across.
Ma'az means Mars in
the Navajo language.
