NASA's InSight lander may have recorded a marsquake

It might not have taken long for NASA's InSight lander to capture a marsquake . The machine's seismometer recorded trembling on April 6th that seems to have come from within Mars, rather than an above-ground source like the wind or InSight itself. Although the event was too quiet to say much about Mars' insides (it would have been difficult to detect on Earth), it suggested that Mars is, in fact seismically active. There were other events on March 14th, April 10th and April 11th, although they were faint enough as to have been ambiguous.
