DESCRIPTION:"NASA’s InSight lander has been recording on Mars since Nove
 mber 2018. InSight is the first dedicated geophysical lander to be sent to
  another planet and it’s mission objective was to determine the internal
  structure of Mars. To do this the lander is equipped with a seismic stati
 on\, a heat flow probe\, meteorological sensors and an X-band radio transp
 onder and transmitter designed to measure the planet’s rotation. The pri
 me mission (two Earth years – one Mars year) was a huge success and InSi
 ght is now well into its extended mission. Mars is seismically active and 
 the MarsQuake Service has catalogued over 1200 marsquakes so far. These qu
 akes are mostly small in magnitude but\, due to the low noise floor on Mar
 s\, they have been used\, as on Earth\, to determine the internal structur
 e of the planet from the core to the crust. In this talk I will introduce 
 my work with the MarsQuake Service\; discuss the Martian seismic catalogue
 \; demonstrate the differences between marsquakes and earthquakes\; and re
 port on the latest results for the interior structure of Mars."
