NASA lander detects first sign of ‘marsquake’
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.
