NASA records sound of ‘Marsquake’ for first time as tremors detected on Red Planet

THIS is the incredible sound of a ‘Marsquake’, which has been detected on the Red Planet for very first time – proving there is at least geological life on Mars.

The quake was recorded by the NASA InSight lander and detected by a set of silicon sensors developed in the UK.

The distinct signal was detected on April 6, the 128th Martian day, or sol, of the mission, which is supported by the UK Space Agency.

Details of the tremors were revealed today at the Seismological Society of America conference in Seattle, USA.

Audio of the Mars tremor, accompanied with footage of the probe has been released by French space agency CNES.

Sue Horne, Head of Space Exploration at the UK Space Agency, said: “Thanks to the Apollo missions of the 1960s we know that moonquakes exist. So, it’s exciting to see the Mars results coming in, now indicating the existence of marsquakes which will lead to a better understanding of what’s below the surface of the red planet.”

LIFE ON MARS

The French-made SEIS module which captured the tremors includes three Short Period sensors (SEIS SP) developed in partnership by Imperial College London, Oxford University and STFC RAL Space, with £4million in funding from the UK Space Agency.

These sensors, carved out of silicon, can detect motion at sub-atomic scales.

Prof Tom Pike of Imperial College London, leading the UK contribution, said: “This is what we what we were all waiting for, the first quivering of the planet picked up by our sensors.

“We worked hard to develop the most sensitive silicon sensors on Earth to send to Mars as part of SEIS. Up to now we didn’t know if even that was going to be good enough.

MARSQUAKE

“But it looks like Mars, although very much quieter than Earth, is giving us seismic signals we are able to clearly detect. Our first investigation of the interior of another planet is now underway.”

In December, the British-developed silicon sensors of SEIS captured the first sounds ever recorded directly from Mars – a haunting, low rumble caused by vibrations from the wind.

Recording this wind allows scientists to separate “noise” from actual marsquakes.

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.

Dr Neil Bowles, from the University of Oxford’s Department of Physics, said: “Seeing the first likely ‘marsquake’ is really exciting and it shows the fantastic performance of the SEIS instrument.

“We can now start to characterise the types of signals we see on Mars to try and understand how this relates to the structure of planet.”

Science minister Chris Skidmore said: “Detecting these quakes on a planet 140 million miles from Earth is a spectacular feat of science and engineering – a testament to the UK’s world leading science and engineering space sector.”
