InSight Mission – UPSC Prelims

  • InSight is NASA’s Discovery Program mission dedicated to exploring the deep interior of Mars.
  • InSight stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport.
  • This Mission aims at studying the deep interiors of Mars. It is the first program to analyze the interior of the Red Planet, beneath its surface i.e. its crust, mantle, and core.
  • InSight mission is part of NASA’s Discovery Program (1992). Discovery Program is a series of Solar System exploration missions. NASA funds these missions through its Planetary Missions Program Office.
  • It has a stationary lander equipped with seismometer and heat transfer probe on surface of Mars to study red planet’s early geological evolution.
  • The robotic lander performs a radio science experiment to study internal structure of Mars by deploying seismometer and a burrowing heat probe.
  • It measures Mar’s vital signs such as pulse (seismology), temperature (heat flow probe) and reflexes (precision tracking).
  • It lets scientists understand how different its crust, mantle and core are from Earth.
  • It helps in understanding processes that shaped rocky planets of inner solar system (including Earth) more than four billion years ago.
