NASA lan­der de­tects first sign of ‘marsquake’

The Tribune (SLO) - - Insight -

It sounds like a sub­way train rush­ing by. Or a plane flying low over­head. But it’s some­thing much more ex­otic: In all like­li­hood, the first “marsquake” ever recorded by hu­mans.

NASA’s In­Sight mis­sion de­tected the quake on April 6, four months after the lan­der’s seis­mome­ter was in­stalled on the Mar­tian sur­face.

“It’s so ex­cit­ing to fi­nally have proof that Mars is still seis­mi­cally ac­tive,” Philippe Lognonne, a geo­physi­cist at the In­sti­tut de Physique du Globe de Paris, said in a state­ment.

Re­searchers don’t yet know what caused the quakes.
