DESCRIPTION:NASA’s InSight (Interior Exploration using Seismic Investiga
 tions\, Geodesy and Heat Transport) mission landed in Elysium Planitia\, M
 ars\, in November 2018\, aiming to answer key questions on the interior of
  Mars and\, by inference\, the formation of rocky planets in general. In o
 rder to do so\, InSight deployed a seismometer (SEIS – the Seismic Exper
 iment for Interior Structure) on the surface – the first fully robotic d
 eployment on another planet. After less than three years of collecting dat
 a\, we can now provide constraints not only on the present-day tectonic ac
 tivity of Mars\, but also on the radial extent and properties of the crust
 \, mantle and core of the planet\, based on the analysis of seismograms of
  about 10 teleseismic marsquakes. These results provide the present-day gr
 ound truth for any thermodynamical and planetary formation models and poin
 t to differences between the Earth and Mars. In the meantime\, InSight con
 tinues to record and provide new data that help to tighten the constraints
  and understand the Martian interior in increasing detail.
