"We're trying to design a noise-cancellation headphone system for our seismometer", InSight principal investigator Bruce Banerdt said. The seismometer will be moved to the Martian surface in the coming weeks.
InSight sensors captured the low rumble caused by vibrations from the wind on December 1, NASA said.
InSight, which landed on 26 November 2018, will study the inside of Mars to learn how planets, moons and meteorites with rocky surfaces, including the Earth and its Moon, formed. The low-frequency rumblings were collected by the InSight lander during its first week of operations at Mars.
It's the sounds of Mars.
But for InSight's first mixtape, none of the lander's instruments have been deployed.
The noise is of the wind blowing against InSight's solar panels and the resulting vibration of the entire spacecraft. The air pressure sensor, part of the Auxiliary Payload Sensor Subsystem (APSS), which will collect meteorological data, recorded these air vibrations directly.
"Humans are multisensor people, and now we have two of our sensors turned on with this mission", with both audio and visual data streaming back to Earth, Don Banfield, the science lead for the air pressure sensor, said during the news conference. The wind was estimated to be blowing 10 to 15 miles per hour from northwest to southeast, which matched the direction of dust devil streaks observed from another NASA spacecraft in orbit.
The InSight team hadn't planned on capturing the wind sounds, calling it an "unplanned treat". That lander is scheduled to arrive on Mars in two years and will have microphones on board to record direct sounds, including the sound of the landing.
Once the deployment is complete, InSight's measuring instruments and probes will hopefully give us more data about Mars's interiors, including the planet's seismic tremors and how heat flows through its structure. "We are really going to have an opportunity to understand the processes that control the early planetary formation".
