A Marsquake detector designed in part by Imperial engineers is set to help reveal Mars’ inner structure.

, the NASA probe which contains the detector, was launched on 5 May 2018 from the in California, and touched down on the Red Planet at 19:53 GMT on 26 November. 

The first mission to study the deep interior of will generate unprecedented data about its inner structure. Evidence of a liquid core could hint at the likelihood of previous life on the Red Planet billions of years ago.

Mission to Mars! – Imperial's role

Professor Tom Pike, from Imperial’s , is part of the Mars Insight team. The Imperial team designed and fabricated silicon sensors as part of the Seismic Experiment for Interior Structure (SEIS), which will detect tremors below the Martian surface.

From the tremors, the mission will build a picture of Mars’ interior and help researchers detect a solid or liquid core. The remains of a liquid core could suggest that Mars once had a . Like on Earth, the field would have protected it from harmful  billions of years ago. Back then, Mars then was much warmer and wetter, and might have been capable of harbouring early life.

Professor Pike said: “Studying Mars lets us travel to the solar system’s ancient past. While Earth and ' tectonic systems have destroyed most of the evidence of their early history, much of the Red Planet has remained static for more than three billion years.”
