NASA records sound of space rock crashing into Mars


For the primary time, NASA has captured the bizarre sound of a meteoroid crusing by means of one other planet’s ambiance and crashing to the bottom.

The recording, posted Sept. 19 on YouTube, combines “seismic and acoustic waves” detected when an area rock hit Mars on Sept. 5, 2021, the NASA Jet Propulsion Laboratory says in a news release.

Lasting only about 3 seconds, the sound begins with a hiss — the rock flying by means of the sky — and ends with “bloops.”

“It was the primary time the sound of a meteoroid influence was captured occurring on one other planet, and it might not be what you expect,” the lab reviews.

“You hear three ‘bloops’ representing distinct moments of the influence: the meteoroid getting into Mars’ ambiance, exploding into items, and hanging the bottom. The peculiar sound is attributable to an atmospheric impact that’s additionally been noticed in deserts on Earth, the place lower-pitched sounds arrive earlier than high-pitched sounds.”

The meteoroid — “the time period for incoming house rocks earlier than they hit the bottom” — exploded into at the least three items, leaving three distinct craters, scientists say.

NASA says its InSight lander picked up the seismic waves and NASA’s Mars Reconnaissance Orbiter flew over the influence web site and photographed “three darkened spots on the floor.”

A paper revealed Sept. 19 within the peer-reviewed journal Nature Geoscience reviews NASA has recorded 4 meteoroid impacts on Mars since August 2021, “between 53 and 180 miles (85 and 290 kilometers) from InSight’s location.”

All 4 produced marsquakes (like earthquakes) within the 2.0 magnitude vary, officers say.

“Researchers have puzzled over why they haven’t detected extra meteoroid impacts on Mars,” NASA says.

“The Red Planet is subsequent to the photo voltaic system’s most important asteroid belt, which offers an ample provide of house rocks to scar the planet’s floor. Because Mars’ ambiance is simply 1% as thick as Earth’s, extra meteoroids go by means of it with out disintegrating,” NASA says.

It’s potential extra impacts have occurred since InSight landed in 2018, however they had been “obscured by noise from wind or by seasonal modifications within the ambiance,” the InSight staff says.

The paper’s lead writer, Raphael Garcia of France’s Institut Supérieur de l’Aéronautique et de l’Espace in Toulouse, says such influence websites “are the clocks of the photo voltaic system.”

“Scientists can approximate the age of a planet’s floor by counting its influence craters: The extra they see, the older the floor,” he says within the information launch.
