NASA第一次捕捉到火星表面的聲頻
NASA Captures Audio of Mars Surface for the First Time (Listen)
What does Martian wind sound like? Now we know as for the first time in history sound has been recorded on another planet’s surface.
On Friday NASA released audio from its InSight Mars lander, which touched down on the planet’s surface last week and transmitted audio of wind and vibration sounds deflecting off the lander’s 7-foot solar panels.
Scientists did not initially expect to capture such clear sound and were surprised upon listening to the transmission. NASA’s Jet Propulsion Laboratory stated in a press release, “Capturing this audio was an unplanned treat”… “But one of the things [the InSight mission] is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves.”
NASA scientists described the sound as from a northwest wind blowing 10-15 mph and atmospheric vibrations picked up by sensors on Dec. 1, according to the official media release:
InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 15 mph (5 to 7 meters a second) on Dec. 1, from northwest to southeast. The winds were consistent with the direction of dust devil streaks in the landing area, which were observed from orbit.
NASA posted the audio to YouTube on Friday, which can be listened to here (begins :35 mark):
