NASA lander detects 'first Marsquake' after touching down on Mars

The American space agency's InSight lander appears to have detected its first seismic event on Mars after it touched down on the Red Planet in November last year. It is the first seismic signal detected on the surface of a planetary body other than the Earth and its Moon, the BBC reported. InSight's scientists say the character of the rumble reminds them very much of the type of data the Apollo sensors gathered on the lunar surface. Researchers can then compare this with Earth's internal rock layering, to learn something new about the different ways in which these two worlds have evolved.
