NASA marks Mars quake
NASA has reported the first ‘Marsquake’ ever recorded.
NASA's robotic probe InSight has marked what appears to be the first time a seismological tremor has been recorded on another planet.
It comes five months after InSight - a spacecraft designed specifically to study the deep interior of Mars - touched down on the surface to begin its two-year seismological mission.
Scientists are still poring over the data to determine conclusively what happened, but early analysis suggests trembling originated from inside the planet, the Jet Propulsion Laboratory in California said.
“We've been collecting background noise up until now, but this first event officially kicks off a new field: Martian seismology,” InSight principal investigator Bruce Banerdt said in a statement.
No estimated Earth-magnitude equivalent was immediately given for the apparent marsquake.
