Rank 28 documents InSight — the 694 kg JPL Discovery lander that placed the first seismometer on another planet and measured Mars's core size before dust choked its solar arrays in December 2022. Bruce Banerdt's team landed in Elysium Planitia on 26 November 2018 aboard Atlas V 401, deploying SEIS beneath a wind and thermal shield to detect hundreds of marsquakes and meteor impacts. Twin MarCO cubesats relayed entry telemetry on the first interplanetary CubeSat demonstration. The HP³ heat-flow mole stalled in unexpected soil, but seismic data still delivered a direct core-radius measurement and interior structure map no orbiter could provide. Heritage Collector renders the SEIS dome lander, Mars interior cutaway, and INSIGHT vertical spine exactly as the master PNG dictates.
