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 Perseverance mission sol 12 (March 2) 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.
<<The word Navajo is an exonym: it comes from the Tewa word Navahu, which combines the roots nava ('field') and hu ('valley') to mean 'large field'. It was borrowed into Spanish to refer to an area of present-day northwestern New Mexico, and later into English for the Navajo tribe and their language. The Navajo refer to themselves as the Diné ('People'), with their language known as Diné bizaad ('People's language') or Naabeehó bizaad.
Navajo is a Southern Athabaskan language of the Na-Dené family, through which it is related to languages spoken across the western areas of North America. Navajo is spoken primarily in the Southwestern United States, especially on the Navajo Nation. It is one of the most widely spoken Native American languages and is the most widely spoken north of the Mexico–United States border, with almost 170,000 Americans speaking Navajo at home as of 2011. The language has struggled to keep a healthy speaker base, although this problem has been alleviated to some extent by extensive education programs in the Navajo Nation.
The language has a fairly large phoneme inventory; it includes several uncommon consonants that are not found in English. Its four basic vowels are distinguished for nasality, length, and tone. It has both agglutinative and fusional elements: it relies on affixes to modify verbs, and nouns are typically created from multiple morphemes, but in both cases these morphemes are fused irregularly and beyond easy recognition. Basic word order is subject–object–verb, though it is highly flexible to pragmatic factors. Verbs are conjugated for aspect and mood, and given affixes for the person and number of both subjects and objects, as well as a host of other variables.
In 1943 the men collaborated on The Navajo Language, a dictionary organized by the roots of the language. In World War II, the United States military used speakers of Navajo as code talkers – to transmit top-secret military messages over telephone and radio in a code based on Navajo. The language was considered ideal because of its grammar, which differs strongly from that of German and Japanese, and because no published Navajo dictionaries existed at the time.>>
Sounds a lot like an ophthalmologist's YAG posterior capsulotomy laser, the laser treatment used to remove scar tissue from around a cataract lens implant. Click-click-click-click!
It's amazing but if I am not mistaken that sounds just like my old wind up Tim ex watch circa 1970s when I forgot to take it off and slept with it beside my ear. It's the watch that takes a licking but keeps on ticking. You could say there is no new sound discovered in the world, just replayed sound from the past.
