J'aime beaucoup la description du laser utilisé pour analyser le rocher.
The Perseverance rover currently exploring Mars has found something strange: A weird green rock that has scientists puzzled.
The laser used for this analysis is super powerful, able to heat its targets to 18,000 degrees Fahrenheit. And the instrument also includes a microphone, which records audio samples that are used to hear how far the laser is penetrating into a sample and can even give clues to the hardness of the rock.
